Installation
Guidelines
If the POU is installed in a cabinet the ambient temperature should be no greater than 40°C.
Install the POU such that the amount of airflow required for safe operation of equipment is not
compromised.
Mount the POU 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 POU relies on the building installation for protection from over-current conditions. A Listed
circuit breaker is required within the building installation. The circuit breaker should be sized
according to the POU’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 POU must
be connected to an earthed socket-outlet.
The POU is intended for Restricted Access Locations only and only service personnel should
install and access the POU.
For pluggable equipment, install the POU so that the input plug or appliance coupler may be
disconnected for service.
Sequential power-up of devices powered by the POU is recommended to avoid high inrush
current.
Caution: Disconnect all power cords before servicing.
