How to Install the SP Series High-Amperage Plug and Receptacle
This guide provides step-by-step instructions for safely installing and configuring the SP Series high-amperage plug and receptacle system.
Estimated time: 1h
Tools needed:
Screwdriver, Wire strippers, Multimeter, Torque wrench
Supplies needed:
Mounting screws, Terminal connectors, Gaskets, Sealer tape
- Disconnect power
Before starting the installation, ensure that all sources of power to the circuit are disconnected to eliminate the risk of electrical shock.
- Mount the receptacle
Secure the receptacle to the mounting surface using the provided screws. Ensure that watertight seals are used under the heads of the screws to maintain IP66/IP67 protection.
- Connect the main conductors
Use flexible cables rated between 2/0 and 777 MCM. Tighten the threaded lugs until the tapered section is in solid contact with the terminal, applying a torque of 30 ft-lbs (40 N.m).
- Wire the pilot contacts
Connect the auxiliary/pilot contact leads in series within the power control circuit according to the provided wiring diagram.
- Attach the handle
Insert the cable through the cable gland and handle before tightening the phase conductor. Assemble the handle with the screws and gasket supplied.
- Verify connections
Use a multimeter to check the continuity of the ground circuit and ensure all connections are secure and properly torqued.
- Test the installation
Reconnect power to the circuit and test the functionality of the plug and receptacle by engaging and disengaging the plug while ensuring the pilot circuit operates correctly.
