Electrical Installation
Step 1 – Receptacle evaluation
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.
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.
Troubleshooting

circuit/main with fuse or circuit breaker protection. Connection to any
other type of wall receptacle may result in a shock hazard.
Possible Cause
1. Open breaker
2. Loose power cord
1. Overload
2. Amperage meter is
damaged
1. Sustained overload
2. Excessive ambient or
internal temperatures.
3. Faulty breaker
Solution
Reset Breaker check if
plug is completely
