Electrical Installation
Ensure that the plug type of your PDU unit (e.g. NEMA 5-15P, NEMA 5-
20P, NEMA L5-30P) matches the wall receptacle type that you are using.
Step 1 – Receptacle evaluation
PDU must be plugged into a three-wire, grounded wall receptacle only.
The wall receptacle must also be connected to an appropriate branch
circuit/main with fuse or circuit breaker protection. Connection to any
other type of wall receptacle may result in a shock hazard.
CAUTION!!
Step 2 – Plug the PDU into the wall receptacle
Step 3 – Attach equipment
Before attaching equipment, it is important to calculate the total load that you
will be placing on the PDU. It is extremely important not to exceed the PDU's
maximum current load (as outlined in the Specifications section). In order to
determine your total load, simply add up the amperage of your devices and
ensure that it does not exceed the unit’s capacity.

type only)
1. Overload
2. Amperage meter is
damaged
Reduce the load on the
PDU until the overload
is gone.
