Safety and General Information
• Adhere to all national and local electrical codes.
• All wiring must be performed by a qualified electrician.
• Changes and modifications to this unit not expressly approved by APC could void the warranty.
• This UPS is intended for indoor use only.
• Do not operate this UPS in direct sunlight, in contact with fluids, or where there is excessive dust or humidity.
• Be sure the air vents on the UPS are not blocked. Allow adequate space for proper ventilation.
• For a UPS with a factory installed power cord, connect the UPS power cable directly to a wall outlet. Do not use
surge protectors or extension cords.
• The equipment is heavy. Always practice safe lifting techniques adequate for the weight of the equipment.
• The batteries are heavy. Remove the batteries before installing the UPS and external battery packs (XLBPs), in a
rack.
• Always install XLBPs at the bottom in rack-mount configurations. The UPS must be installed above the XLBPs.
• Always install peripheral equipment above the UPS in rack-mount configurations.
• Additional safety information can be found in the Safety Guide supplied with this unit.
Deenergizing safety
• The UPS contains internal batteries and may present a shock hazard even when disconnected from AC and DC
power.
• The AC and DC output connectors may be energized by remote or automatic control at any time.
• Before installing or servicing the equipment check that the:
– Mains circuit breaker is in the OFF position
– Internal UPS batteries are removed
– XLBP battery modules are disconnected
Electrical safety
• For models with a hardwired input, the connection to the branch circuit (mains) must be performed by a
qualified electrician.
• 230 V models only: In order to maintain compliance with the EMC directive for products sold in Europe, output
cords attached to the UPS must not exceed 10 meters in length.
• 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 input
power to 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 and with or without a
yellow stripe.
• The UPS input ground conductor must be properly bonded to 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.
