How to Install the PF and PFQ Series Plugs and Receptacles
This guide provides step-by-step instructions for the installation and wiring of PF and PFQ series plugs and receptacles, ensuring safe and reliable operation.
Estimated time: 1h
Tools needed:
7/8" wrench or socket, 5/16" allen wrench, 10 mm wrench (for PFQ only), Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Heat shrink tubing
- Verify Power is Off
Before starting the installation, ensure that all sources of power to the circuit are disconnected to eliminate the risk of electrical shock.
- Mount the Device
Secure the PF or PFQ device to the designated location using the mounting screws provided. Ensure that the locking cam on the receptacle is easily accessible.
- Connect the Conductors
Strip the conductors to 0.5 inches (12 mm) and connect them to the respective terminals as per the wiring instructions. Use the appropriate lugs and ensure that the neutral and ground wires are positioned above the phase wires.
- Apply Heat Shrink Tubing
After connecting the conductors, apply heat shrink tubing over the lugs and terminals to prevent short circuits.
- Tighten Terminal Screws
Tighten the terminal screws until hand tight using a 4 mm flat screwdriver. Ensure that the recommended torque of 13 in-lb (1.5 N-m) is applied.
- Assemble the Handle
Attach the handle cover using the 8 mm allen tool and the six screws provided. Ensure that the handle is securely fastened.
- Calibrate the Mechanical Locking
Rotate the locking cam to the desired position to engage or disengage the auxiliary and pilot contacts as needed.
