Three-Phase Rack PDU — Installation and Operation Manual 3
How to Install the Rack PDUs
Installation guidelines
• If the PDU is installed in an enclosed communications rack, the
recommended maximum ambient temperature should be no greater
than 45°C.
• Install the PDU so that the amount of air flow required for safe
operation of the equipment is not compromised.
• Install the PDU so that there is not an uneven mechanical load.
• Follow the nameplate ratings when connecting equipment to the
supply circuit. Take into consideration the effect that overloading
the circuits might have on over-circuit protection and supply
wiring.
• Maintain reliable earthing of the PDU. Give particular
consideration to supply connects that do not directly connect to the
branch circuit.
• Install the PDU so that the power plug may be disconnected for
service.
Mounting options
You can install Rack PDUs in one of two ways: using toolless mounting
pegs or the mounting brackets. The Rack PDU mounts in the rear of the
enclosure, in the channel directly behind the rear vertical mounting rails.
Before you begin to install the Rack PDUs, choose a location in the
enclosure and decide on the mounting method.
