| Deenergizing safety:
The UPS contains internal batteries and may present a shock hazard even when disconnected from the branch circuit (mains). Before installing or servicing the equipment check that the:
- An input circuit breaker is in the OFF position.
- Internal UPS batteries are removed.
- XLBP battery modules are disconnected.
|
Electrical safety:
- Use tools with insulated handles.
- Do not handle any metallic connector before the power has been disconnected.
- For models with a hardwired input, the connection to the branch circuit (mains) must be performed by a qualified electrician.
- The protective earth conductor for the UPS carries the leakage current from the load devices (computer equipment). An insulated ground conductor is to be installed as part of the branch circuit that supplies the UPS. The conductor must have the same size and insulation material as the grounded and ungrounded branch circuit supply conductors. The conductor will typically be green, with or without a yellow stripe.
- Leakage current for a pluggable, Type A UPS may exceed 3.5 mA when a separate ground terminal is used.
- The UPS input ground conductor must be properly bonded to the protective earth at the service panel.
- If the UPS input power is supplied by a separately derived system, the ground conductor must be properly bonded at the supply transformer or motor generator set.

Battery safety :
- Batteries typically last for two to five years. Environmental factors impact battery life. Elevated ambient temperatures, poor-quality utility power, and frequent short-duration discharges will shorten battery life. Batteries should be replaced before the end of life.
- Replace batteries immediately when the unit indicates battery replacement is necessary.
- When replacing batteries, replace them with the same number and type of batteries as originally installed in the equipment.
- Schneider Electric uses Maintenance-Free Sealed Lead Acid batteries. Under normal use and handling, there is no contact with the internal components of the battery. Overcharging, overheating or other misuse of batteries can result in a discharge of battery electrolyte. Released electrolytes are toxic and may be harmful to the skin and eyes.
- CAUTION: Before installing or replacing the batteries, remove jewellery such as chains, wristwatches and rings. Use tools with insulated handles. High short circuit current through conductive materials could cause severe burns.
- CAUTION: Do not dispose of batteries in a fire. The batteries may explode
- CAUTION: Do not open or mutilate batteries. Released material is harmful to the skin and eyes and may be toxic.
