Chapter 2 - Installation

Pre-Installation

· For standard temperature models, the ambient temperature of the installation location, such as
an IT rack, should be no greater than 45°C if the PDU is loaded to its full nameplate current
rating. The ambient temperature of the installation location should be not greater than 60°C if
the PDU normal current load is a maximum 50% of the nameplate and individual receptacle
ratings. (Note: load up to full nameplate rating are permitted during short term abnormal
operating conditions).
· 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 overcurrent protection
and supplied wiring.
· The PDU relies on the building installation for protection from overcurrent. 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
code.
· 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.
· PDU is intended for restricted-access locations. Only qualified service personnel should
install and access the PDU.
· For pluggable equipment, install the PDU so the input plug or appliance coupler may be
disconnected for service.
· The PDU is intended for indoor use only. Do not install the unit in wet or outdoor
environments, and do not install it next to water tanks or plumbing.
· The PDU is intended for use with TN, TT, or IT power supply systems.
