1. Why Compliance Pressure Is Mounting
For the first three years after the Haryana Lifts and Escalators (Amendment) Act came into force in October 2020, enforcement was patchy. Lift inspectors had limited bandwidth, and many residential societies quietly did nothing. That is changing. District-level lift inspection drives in Gurugram, Faridabad, and Panchkula have begun issuing notices to buildings that cannot demonstrate a functioning Emergency Rescue Device (ERD). The penalty exposure under the principal 2008 Act — which the amendment does not repeal — includes fines and, in repeat-offence cases, suspension of the lift operating certificate.
Beyond the legal risk, there is a practical one. Haryana experiences frequent grid outages, particularly in summer months when air conditioning load is high. A lift that drops to a halt with passengers inside is both a liability claim and a reputational problem for any housing society. ERD technology exists specifically to prevent that outcome. The compliance checklist below is designed to help building managers, RWA presidents, and facility teams verify that their lifts meet both the letter and the spirit of the 2020 mandate.

2. The Core ERD Requirement
The amendment inserts a new Section 2A into the 2008 Act. In substance, it requires that:
- Every lift in a building that falls within the Act's scope must be fitted with an Emergency Rescue Device (ERD).
- The ERD must provide a minimum backup duration of 15 minutes under full rated load.
- Switchover from mains to ERD must be seamless — no passenger must experience a drop, jerk, or reversal on power failure.
An older Automatic Rescue Device (ARD) — the 30-second-delay technology that was standard in buildings from the 1990s onward — does not satisfy this requirement. ARDs drop the lift to the nearest floor and open the doors; they do not provide continuous operation. The amendment specifically anticipates ERD-grade, zero-break technology. See our technology overview for a full technical comparison of ARD versus ERD.
2a. What "15 minutes" actually means
The 15-minute figure is a load-rated minimum. It means the ERD battery bank must sustain the lift motor at full rated load (typically 100% of the rated passenger capacity) for 15 continuous minutes. A battery bank sized for a lightly loaded lift or for an older, more efficient motor may fail the test when the lift is full. Battery ageing compounds this: a bank that delivered 20 minutes of backup when new may deliver only 12 minutes after three years of float charging and partial cycling.
The practical implication is that you should specify more than 15 minutes of nameplate backup — 20 to 30 minutes is the field standard — to account for battery ageing over the service interval. Use the ERD Sizing Calculator to compute the exact battery Ah rating for your lift motor and desired backup duration.
2b. What "zero-break switchover" means for your building
True zero-break (also described as "online double-conversion" in UPS terminology) means the inverter output is permanently live on the load side. The mains supply feeds the DC bus through a rectifier; the DC bus feeds the inverter; the inverter feeds the lift. When mains fails, the DC bus transitions from mains-rectified power to battery power in under 3 milliseconds — far below the motor controller's sensitivity threshold. From a passenger perspective, nothing happens. The lift does not slow, does not jolt, does not level.
This matters for compliance because a device that causes even a brief motor interruption — however short — does not meet the seamless operation standard in the amendment. Ask your ERD vendor to provide the switchover time specification in milliseconds.
3. The 7-Point Compliance Checklist
Work through these checks in sequence. Each item maps to either the statutory requirement, a best-practice derived from field installations, or a documentation requirement that lift inspectors commonly request.
| # | Check | Pass Criterion | Evidence Required |
|---|---|---|---|
| 1 | ERD installed (not ARD) | Device is labelled ERD or Emergency Rescue Device; switchover ≤3ms; output is pure sine wave | Vendor datasheet; site label; installation certificate |
| 2 | KVA rating matches motor | ERD KVA ≥ (Motor KW ÷ 0.8) × 1.25; confirmed by load calculation | Motor nameplate photo; sizing calculation; vendor confirmation |
| 3 | Battery bank provides ≥15 min at full load | Nameplate Ah rating ≥ required Ah at 0.45 de-rating factor (15 min); bank is within its rated service life | Battery datasheet; Ah calculation; installation date record |
| 4 | Battery type is adequate | SMF (lead acid) or better; Lithium LiFePO4 preferred for longer life and deeper DoD; no automotive batteries | Battery specification sheet; battery model and date code |
| 5 | Monitoring active (IoT/GSM) | ERD has active remote monitoring; alerts route to facility manager or third-party monitoring service | Monitoring system login; alert log from last 30 days |
| 6 | Annual service completed | ERD and battery bank serviced within last 12 months by authorised service engineer; backup duration verified by test | Service report; engineer credentials; backup test result |
| 7 | HAREDA solar compliance (if applicable) | Buildings with rooftop solar under HAREDA scheme: ERD is solar-capable; solar input is wired and active | HAREDA installation certificate; solar input wiring diagram |
4. ERD Sizing for Your Building
The most common compliance failure is an under-rated ERD. Building managers specify a device based on an approximate motor size rather than a calculated load. The Haryana Lift Act requires backup at full rated load, which means the calculation must use the worst-case duty cycle — fully loaded car, travelling upward, at rated speed.
The standard sizing formula is:
Motor KW = (Load kg × Speed m/s × 9.81) ÷ (1000 × efficiency)
ERD KVA = (Motor KW ÷ 0.8) × 1.25
The table below gives indicative ERD ratings for common residential and commercial lift configurations. Use the ERD Sizing Calculator for a precise result; the table is a planning guide only.
| Lift Capacity | Speed (m/s) | Motor (KW) | ERD Rating (KVA) | SMF Bank (30 min) | Lithium Bank (30 min) |
|---|---|---|---|---|---|
| 6-person (480 kg) | 1.0 | 7.5 | 12 KVA | 24 × 100Ah SMF | 15 × 50Ah LiFePO4 |
| 8-person (630 kg) | 1.0 | 10 | 16 KVA | 24 × 120Ah SMF | 15 × 60Ah LiFePO4 |
| 10-person (800 kg) | 1.5 | 15 | 20 KVA | 30 × 100Ah SMF | 15 × 60Ah LiFePO4 |
| 13-person (1000 kg) | 1.5 | 20 | 25 KVA | 30 × 120Ah SMF | 15 × 80Ah LiFePO4 |
| Commercial (1600 kg) | 2.0 | 37 | 50 KVA | 30 × 200Ah SMF | 15 × 100Ah LiFePO4 |
For high-rise buildings with multiple lifts, a centralised ERD system — where a single large inverter plant serves all lifts — can reduce capital cost and simplify compliance documentation. The Chintel Pardiso installation in Gurugram is an example: a 100 KVA + 200 KVA centralised ERD system serves 18 lifts from a single battery room, with one set of service records covering the entire building. See the ERD specifications page for a comparison of individual versus centralised topologies.
5. Common Compliance Failures
(1) ARD mistaken for ERD — the device drops passengers to the nearest floor rather than maintaining continuous operation. (2) Under-sized battery bank — specified for 15 minutes new but delivering only 8–10 minutes after two years of ageing. (3) Missing service records — the ERD has never been formally tested since installation; no backup duration test on file. (4) Mismatch between ERD KVA rating and motor KW — typically an ERD bought "off the shelf" at a round number without a site-specific load calculation.
Each of these failures is straightforward to remediate. For (1), replace the ARD with a certified ERD. For (2), replace the battery bank and re-test. For (3), commission an annual service with a written backup duration test. For (4), have an engineer perform a site load calculation and confirm the ERD KVA rating is sufficient; in most cases the motor controller manufacturer can provide the nameplate motor KW directly.
A note on battery de-rating: the 15-minute backup figure in the Act is computed at a de-rating factor of 0.45. This means your battery bank's rated Ah capacity is multiplied by 0.45 to account for discharge efficiency, temperature effects, and end-of-life capacity loss. A bank that delivers 15 minutes at 0.45 de-rating when new will deliver less as it ages. The field standard is to specify for 20–30 minutes of backup to preserve compliance margin throughout the battery service life (typically 3–5 years for SMF, 7–10 years for LiFePO4).
6. Documentation You Must Keep
Lift inspectors in Haryana typically request the following documents when conducting a compliance visit. Keep these in a dedicated lift file at site, accessible to the facility manager:
- Installation certificate from the ERD vendor, specifying the device model, KVA rating, and date of installation.
- Battery datasheet including Ah rating, chemistry (SMF / tubular / lithium), voltage, and rated service life.
- Load calculation signed by a qualified electrical engineer, showing the motor KW, ERD KVA sizing, and battery Ah calculation for the specified backup duration.
- Annual service report from an authorised service engineer, including the result of a timed backup duration test (ERD on battery, lift at rated load, time to low-battery shutdown).
- Battery replacement log with dates of any battery replacements and the Ah rating of replacement cells.
- Monitoring log showing that the IoT or GSM monitoring system has been active and has not recorded unresolved alarms in the past six months.
If the building falls under the HAREDA solar mandate, also retain the HAREDA installation certificate and the solar input wiring diagram. For buildings under RERA jurisdiction, the lift compliance file should be available for disclosure to apartment buyers on request.
7. Next Steps — How to Verify Your ERD
If you are unsure whether your building's existing device is an ERD or an ARD, the fastest verification is a controlled mains-failure test: with a trained technician present, switch off the mains supply to the lift machine room while the lift is running between floors. An ERD will show no change in lift behaviour. An ARD will cause the lift to slow, level, and open its doors.
If you are specifying a new ERD — for a new installation, a lift modernisation, or a replacement of a non-compliant ARD — use the ERD Sizing Calculator to establish the correct KVA and Ah ratings for your motor and backup duration target, then compare vendor quotations against the ERD Buying Guide for a structured evaluation framework.
For buildings with multiple lifts or unusual motor configurations (gearless machines, variable-frequency drives, high-speed installations), a site survey by a qualified power electronics engineer is recommended before specification. Centralised ERD topologies, in particular, require careful bus architecture and protection coordination that is beyond the scope of a standard procurement checklist.
