Safety and grounding information
• 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.
