For maintenance teams, facility managers, and elevator service providers, mastering the correct installation, testing, and replacement timelines of this emergency power supply is critical to ensuring passenger safety during crises and compliance with safety audits. Nanjing Zhuye Elevator Parts, a trusted supplier of authentic Otis components, delivers the XCA25302AF1 that meets Otis’ original manufacturing specifications—guaranteeing seamless compatibility, reliable backup power, and long-term durability.
Proper Usage Methods of Otis XCA25302AF1 Emergency Power Supply
1. Pre-Installation & Preparation
Before installation, prioritize safety by shutting off the elevator’s main power supply, isolating the car top circuit, and securing the car top work area with lockout tags. Inspect the new XCA25302AF1 for physical damage—such as dented housing, damaged charging ports, loose battery connections, or electrolyte leakage—defects that can compromise backup power functionality or pose safety hazards. Nanjing Zhuye’s strict quality control process ensures each unit arrives in optimal condition: fully charged battery pack, functional charging module, clear wiring labels, and pre-tested compatibility with Otis’ emergency control systems.
Verify compatibility with your Otis elevator model by cross-referencing the technical manual or consulting Nanjing Zhuye’s technical support team. Ensure three key details align: (1) the power supply’s output voltage (typically 24V DC) matches the elevator’s emergency system requirements, (2) the mounting dimensions fit the car top’s designated space, and (3) the charging voltage range (110–240V AC) is compatible with the building’s electrical system. Using an incompatible emergency power supply can result in failed backup activation, incomplete car descent, or damage to critical safety components.
2. Installation & Configuration Steps
- Mounting the Unit:
- Locate the designated mounting bracket on the elevator car top (typically near the control panel) and secure the XCA25302AF1 using the provided high-torque screws (torque to 3.0–4.0 Nm). Ensure the unit is positioned upright to prevent battery leakage and maintain proper ventilation—minimum 10cm clearance around the housing for heat dissipation.
- Disconnect the old emergency power supply (if replacing) by labeling and removing power cables (charging input, emergency output to control panel) and communication wires (status feedback to main controller). Take detailed photos of the wiring configuration to ensure accurate reinstallation.
- Wiring & Connection:
- Connect the charging input cable to the building’s mains power (via a dedicated circuit) and the emergency output cable to the elevator’s emergency control panel, ensuring correct polarity (+V to positive terminals, -V to negative terminals). Use 4mm² copper wire for connections to handle the power supply’s output current (typically 10–15A).
- Connect the communication wire to the main controller to enable real-time status monitoring (battery charge level, fault alerts). Tighten all terminal screws to Otis’ specified torque (2.0–2.5 Nm) to avoid loose connections and voltage drops.
- Post-Installation Testing:
- Restore power to the elevator (performed by certified Otis technicians only) and conduct two critical tests:
- Charging Test: Verify the power supply’s charging module activates, with the “Charging” indicator light illuminating (typically green). Use a multimeter to confirm the battery voltage gradually rises to the fully charged level (27.6V DC for 24V systems).
- Emergency Activation Test: Simulate a mains power outage by switching off the elevator’s main power. Confirm the XCA25302AF1 automatically activates (red “Emergency” indicator lights up), powers the car lights and intercom, and initiates the elevator’s controlled descent to the nearest safe floor.
- Document installation details, test results, and battery charge levels in maintenance records to demonstrate compliance with Otis’ safety requirements.
- Restore power to the elevator (performed by certified Otis technicians only) and conduct two critical tests:
3. Routine Usage & Maintenance
To preserve the XCA25302AF1’s reliability and extend its lifespan, implement these proactive maintenance practices:
- Monthly Visual Inspections: Check the unit for physical damage, loose connections, or leakage. Verify the “Normal” indicator light is illuminated (confirms battery is fully charged and system is operational).
- Quarterly Battery Testing: Use Otis’ diagnostic software or a multimeter to measure the battery’s open-circuit voltage (should be ≥26.4V DC for 24V systems). Record readings to identify capacity degradation trends.
- Semi-Annual Functional Test: Repeat the emergency activation test to ensure the power supply triggers correctly, delivers stable power, and supports a full descent cycle. Clean the unit’s housing and vents with compressed air to remove dust.
- Annual Comprehensive Inspection: Remove the unit’s cover (by authorized technicians) to inspect internal components: battery terminals for corrosion, charging module for damage, and wiring for fraying. Retighten terminals or replace damaged parts with genuine Otis components from Nanjing Zhuye.
- Battery Calibration: Every 6 months, discharge the battery to 50% capacity and fully recharge it to maintain cell health—this prevents battery memory effect and extends cycle life.
Recommended Replacement Cycle
The service life of the Otis XCA25302AF1 Emergency Power Supply depends on battery chemistry (typically lead-acid or lithium-ion), usage frequency of emergency activation, and environmental conditions. Based on Otis’ engineering standards and Nanjing Zhuye’s technical expertise:
1. Standard Replacement Cycle
- Lead-Acid Battery Variant: Replace every 3–5 years under normal operating conditions (annual emergency activation tests, stable temperature).
- Lithium-Ion Battery Variant: Replace every 5–7 years (benefits from longer cycle life and lower self-discharge rate).
This timeframe accounts for gradual battery capacity degradation—proactive replacement ensures the power supply can deliver sufficient energy for a full emergency descent when needed.
2. Signs That Require Immediate Replacement
Replace the emergency power supply immediately if:
- Battery Failure: Battery voltage drops below 24V DC (fully charged) or fails to hold a charge for more than 30 minutes during testing.
- Emergency Activation Failure: The unit does not activate during power outages, fails to power critical functions, or does not initiate controlled descent.
- Physical Damage: Dented housing, battery leakage, or damaged charging module—compromises electrical safety and functionality.
- Persistent Faults: Repeated error codes (e.g., “Battery Fault,” “Charging Failure”) that cannot be resolved with troubleshooting.
- Safety Compromise: Inability to power the emergency intercom or door opening mechanism—violates passenger rescue requirements and safety regulations.
3. Maintenance to Extend Service Life
- Environmental Control: Ensure the car top is well-ventilated and protected from extreme temperatures (avoid exposure to >50°C or < -10°C). Install a heat shield if the unit is near heat sources (e.g., traction motor).
- Power Stabilization: Install surge protectors in the charging circuit to shield the power supply from voltage spikes—prevents damage to the charging module.
- Minimize Unnecessary Discharges: Avoid frequent simulated emergency activations (limit to quarterly tests) to reduce battery cycle wear.
- Genuine Replacements: When replacement is needed, choose authentic Otis XCA25302AF1 units from Nanjing Zhuye. Counterfeit power supplies use inferior batteries, lack safety certifications, and risk failure during emergencies.
