Units (PDUs)
User Manual

Circuit Breakers
• Branch Rated
• Required with any receptacle with a
lower current rating than the Input
• Under lid or cover on some models
Feed Thru
• Female or Output Connector
• Same Type as Inlet
• No Overcurrent Protection
Step 1: Locating PDUs
-The PowerHOUSE™PDUs are designed to be used in indoor or outdoor locations
-Review labels attach to enclosure for rating
-‘TYPE 1’ indicates Indoor use only, ‘TYPE 3R’ indicates either Indoor or Outdoor use
-Each PowerHOUSE™ PDU should rest on its own base on a level surface with suitable ventilation
-DO NOT locate any PowerHOUSE™ PDU in any area prone to standing water
Step 2: Making and Breaking Connections on PDUs
WARNING:
– Before making or breaking connections to any PowerHOUSE™ PDU make certain the power source feeding
the system is OFF
– DO NOT exceed the voltage rating of the device as identied on the label attached to the enclosure
NOTE: If using the feed thru feature, connect the feed thru BEFORE the input connection is made
-Single-pole Cam Connectors
• When MAKING the connection, begin with the GREEN ground connection, then the WHITE neutral connection
and nish with the remaining HOT connections
• Firmly insert cam device into connector and rotate clockwise until fully engaged and locked
• When BREAKING the connection, begin with the HOT connections, then the WHITE neutral connection and
nish with the GREEN ground connection
-NEMA Locking Connector
• Fully insert the female connector into the male inlet
• Turn connector clockwise until it is fully locked
-LSC 19 Multi-pin Connector
• Align female connector with male inlet and insert, ensuring connection is fully seated
• Spin the locking collar of male inlet until snug
-NEMA Straight Blade Connections
• Fully insert the male plug into the female receptacle
Step 3: Powering Up PDUs
-Best practices dictate that loads are applied gradually the rst time the system is set up
NOTE: PowerHOUSE™PDUs are shipped with breakers in the ‘O/OFF’ position
1. Turn on the power source
2. Beginning with the PDU closest to the power source, move the rst individual circuit breaker to the ‘I/ON’
position
3. Ensure the devices fed by that circuit are ON, tracing the electrical path to the nal device fed by that circuit
4. Repeat steps 2 and 3 for the remaining circuit breakers
NOTE: If the circuit breaker cannot be energized or trips, check the system for continuity, short circuits and
overload, and make the necessary corrections before proceeding
The PowerHOUSE™ line of Power Distribution Units (PDUs) meet stringent requirements for either indoor or
outdoor site applications. This user manual reviews the proper use of the wide range of locking and non-locking
inlet, feed-thru and receptacle versions available. Please take time to review all precautions and warnings in the
manual prior to making the proper connections for use. Store this manual in a safe location for future reference.

b. Check for short circuits in the cabling or load device and correct as needed
5. For those receptacles that include a GFCIs:
a. Ensure the GFCIs are set by pressing the ‘RESET’ button
6. If a GFCI trips, identify source of current leakage and correct before resetting the GFCI
a. Check to see if the circuit is overloaded and reduce loads as needed
b. Check for short circuits in the cabling or load device and correct as needed
