Circuit Breaker Orientation Limitation
Usually a PDU can be mounted in any orientation. However, when mounting a PDU with circuit breakers, you
must obey these rules:
 Circuit breakers CANNOT face down. For example, do not horizontally mount a Zero U PDU with circuit
breakers on the ceiling.
 If a rack is subject to shock in environments such as boats or airplanes, the PDU CANNOT be mounted
upside down. If installed upside down, shock stress reduces the trip point by 10%.
Note: If normally the line cord is down, upside down means the line cord is up.
Rack-Mounting the PDU
This chapter describes how to rack mount a Legrand PDU.
Rackmount Safety Guidelines
In Legrand products which require rack mounting, follow these precautions:
 Operation temperature in a closed rack environment may be greater than room temperature. Do not
exceed the rated maximum ambient temperature of the Power Distribution Units. See
Specifications (on page 397) in the User Guide.

Ensure suffici
ent airflow through the rack environment.
 Mount equipment in the rack carefully to avoid uneven mechanical loading.
 Connect equipment to the supply circuit carefully to avoid overloading circuits.
 Ground all equipment properly, especially supply connections, to the branch circuit.
