Rack PDU VP9559, VP7552, and VP7551Instruction Manual
4. CHAPTER 2 - INSTALLATION
4.1. INSTALLATION
1. Using appropriate hardware, mount unit to rack. See next section for examples.
2. Plug PDU into an appropriately-rated and protected branch-circuit receptacle.
3. Plug in the devices to be powered by the PDU.
4. Turn on each device connected to the PDU. Sequential power-up is recommended to avoid high in-
rush current.
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 considera-
tion 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
NOTE
Branch Circuit should be sized based on the PDU's nameplate electrical rat-
ing. A 12 Amp rated PDU is intended for use on a 15 Amp Branch Circuit,
while a 16 Amp rated PDU is intended for use on a 20 Amp Branch Circuit.
For Global Units a 16 Amp rated PDU is intended for use on a 16 Amp
Branch Circuit.
