2. Electrical safety and installation specifications
Grounding requirements
The equipment must be installed with a protective ground wire first, and it should be disconnected last when dismantled10.
Ungrounded operation is prohibited, and the cable flame retardant level must meet UL1581 VW-1 or IEC 60332-3-22 standards10.
Anti-static measures
Anti-static wrist straps must be worn before operation, and only touch the edge of the board without components when holding the board10.
Heat dissipation and wiring
Wiring is prohibited at the air inlet and outlet, and the distance between the cable and the heat source is ≥30mm10.
Recommended installation space: front ≥500mm, rear ≥200mm, side ≥200mm (ensure ventilation)4.
3. Key points of battery maintenance
Charge and discharge management
Fully charge within 24 hours after discharge to avoid capacity decay26.
Regular activation: charge once every 3 months (≥4 hours); fully charge and discharge every 4-6 months (every 2 months in high temperature areas)2.
Life protection
Standard operating temperature is 25ºC. Long-term high temperature (>25ºC) will shorten the life, and low temperature (<25ºC) will reduce the capacity2.
Avoid deep discharge and set the upper limit of discharge time (default 16 hours, maximum 24 hours)6.
Annual maintenance
Capacity test: discharge to the undervoltage alarm point and refresh the battery capacity6.
Connection check: Use a torque wrench to check the torque of the battery screws and mark to prevent loosening6.
IV. Installation and intelligent management
Installation process
Support tower installation, built-in battery plug and play14.
Power module supports hot swapping, easy maintenance and expansion49.
Intelligent monitoring
Communication interface: SNMP/MODBUS/dry contact/USB, support remote management17.
Alarm function: real-time alarm by email/SMS, real-time status display on LCD interface37.
Delayed shutdown: safely shut down the operating system and applications14.
V. Troubleshooting and safety warnings
Prohibited operations: Removing power cables without powering off, altering equipment identification, and using leakage protection circuit breakers 10.
Overload response: Switch to bypass within 0.1 seconds when the load is ≥150% to protect the device 35.
Battery abnormality: If the connection point is loose or the capacity is insufficient, please contact technical support immediately 6.
