Before You Begin

Safety and grounding information

Read the following information before installing or operating your APC Power

Electrical Distribution Unit (PDU).

Hazard

•This PDU is intended for indoor use only.

•Do not install this PDU where excessive moisture or heat is present.

•Never install any wiring, equipment, or PDU during a lightning storm.

•Plug this PDU into a three-wire, grounded power outlet only. The power outlet must be connected to appropriate branch circuit/mains protection (fuse or circuit breaker). Connection to any other type of power outlet may result in a shock hazard.

•Use only the supplied brackets for mounting.

•Do not use an additional extension cord or adapter with the primary power cord.

•Do not work alone under hazardous conditions.

•Check that the power cord, plug, and socket are in good condition.

•To reduce the risk of electric shock when you cannot verify grounding, disconnect the PDU from the power outlet before installing or connecting equipment. Reconnect it to the power outlet only after you have made all connections.

•Pluggable equipment includes a protective earth connector, which carries the leakage current from the load devices (computer equipment). Do not exceed a total leakage current of 3.5 mA.

•Do not handle any kind of metallic connector before the power has been removed.

•Use one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock from touching two surfaces with different grounds.

•This unit does not have any user-serviceable parts. Repairs are to be performed only by factory-trained service personnel.

•Always install the equipment as shown in the Installation Manual.
