BASIC RACK PDU
4
Installation
Instructions
1. Using appropriate hardware, mount PDU to rack (see
Mounting
section for additional
instructions.
2. Plug PDU into de-energized 30 Amp branch circuit receptacle.**
3.
Connect devices into PDU’s output receptacles. It is recommended that the devices are
turned off until all devices are connected to PDU
4. Turn on branch circuit to energize PDU.
5. Power on devices. Sequential power up is recommended to avoid high inrush current.
**Branch Circuit should be sized based on the PDU’s nameplate electrical rating. A 24 Amp
rated PDU is intended for use on a 30 Amp Branch Circuit. For Global Units a 32 Amp rated
PDU is intended for use on a 32 Amp Branch Circuit.
Guidelines
•
If the PDU is installed in a cabinet the ambient temperature of the rack should be no greater
than 45
C.
•
Install the PDU such that the amount of airflow required for safe operation of equipment is not
compromised.
•
Mount the PDU so that a hazardous condition is not achieved due to uneven mechanical
loading.
•
Follow nameplate ratings when connecting equipment to the branch circuit. Take into
consideration the effect that overloading of the circuits might have on over-current protection
and supply wiring.
•
The PDU relies on the building installation for protection from over-current conditions. A
certified overcurrent protection device is required in the building installation. The overcurrent
protection device should be sized according to the PDU’s nameplate ratings and local/national
electrical codes.
•
Reliable earthing of rack-mount equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit. The PDU
must be connected to an earthed socket-outlet.***
•
The PDU is intended for Restricted Access Locations only and only qualified service
personnel should install and access the PDU.
•
For pluggable equipment, install the PDU so that the input plug or appliance coupler may be
disconnected for service.
•
Sequential power-up of devices powered by the PDU is recommended to avoid high inrush
current.
•
Caution:
Disconnect all power cords before servicing.
•
The PDU is intended for use with TN, TT, or IT power supply systems
***XP Series PDUs may optionally be configured as Isolated Ground units. All Isolated
Ground units will be shipped with an enclosure grounding cable. This cable must be
connected between the enclosure and a reliable safety ground.
