Explanation of procedures
The procedures in this manual provide instruction for electricians on how to connect utility conductors to
the PDU Main Input switch and an Emergency Power Off (EPO) switch to the user connection plate.
Review the information provided in the InfraStruXure Configure-To-Order (CTO) report and
accompanying documentation for instructions specific to your installation, and always follow the NEC
and local codes. Before an electrician begins connecting the system, an APC Field Service Engineer
must:
• Position and level the Symmetra PX UPS, InfraStruXure PDU, and, if applicable, the XR Battery
Enclosure.
• Exchange side panels and attach the Symmetra PX UPS, InfraStruXure PDU, and XR Battery
Enclosure.

Access the PDU Main Input switch
1. Open the back doors of the PDU, unlock the top, smaller door, using the provided red key.
2. Loosen the two screws holding the larger, hinged door in place.
Attach conduit to the PDU for the input conductors
1. Remove the rectangular gland plate by loosening the captive screws, using a Phillips or standard
screwdriver:
For wiring under a raised floor: Remove the plate in the floor of the PDU.
InfraStruXure Power Distribution Unit 40kW Instructions for Electricians
5
For overhead wiring: Remove the user connection plate from the top of the PDU.
2. Cut an appropriately-sized hole in the gland plate for the conduit.
3. Re-attach the gland plate.
4. Install a lock-nut and bushing to the conduit.
5. Thread the conduit through the hole.

InfraStruXure Power Distribution Unit 40kW Instructions for Electricians
Install a circuit breaker
Warning: When you connect the InfraStruXure PDU to utility power, you must install a
circuit breaker to protect the PDU against over-current.
Determine the amperage of the circuit breaker that you need to install:
Input Voltage
Circuit Breaker Amperage
208V
175A
480V
80A
600V
60A
Route the input conductors to the Main Input switch
For overhead wiring, run the input conductors directly to the Main Input switch.
For wiring under a raised floor, run the input conductors through the wireway (
within the PDU to the Main Input switch.
)

Connect input conductors
Electrical Hazard: A licensed electrician must connect input conductors to the PDU!
At the Main Input switch, connect the input wiring according to the labels on the switch and the illustrations
below. See the table “Torque specs and tools required” on page 3 for specific information about connecting to
each terminal.
Warning: Connect the conductors to the terminals according to the labels on the terminals.
Use copper conductors only.
