How to Install the Haz Loc DS/DSN/DR/DSDC Connectors
This guide provides step-by-step instructions for safely installing and wiring the Haz Loc DS/DSN/DR/DSDC connectors in hazardous locations.
Estimated time: 45m
Tools needed:
Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Color-coded gaskets
- 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 connector
Secure the connector to the mounting surface using the provided screws. Ensure that the connector is mounted with the latch at the top and at a downward angle whenever possible.
- Prepare the wiring
Strip the cable sheath and individual wires to the lengths specified in Table 4 of the documentation. Ensure that the stripped wire lengths meet the requirements for the specific model being installed.
- Connect the wires
Back out the terminal screws on the connector enough to insert the stripped wires. Insert each wire into the appropriate terminal and tighten the screws to the torque specified in Table 5.
- Assemble the connector
Assemble the connector with the color-coded gasket and secure it using the provided screws. Ensure that the cable is not under tension and that the cable jacket extends into the handle for proper strain relief.
- Test the installation
Once the installation is complete, restore power to the circuit and use a multimeter to verify that the connections are secure and functioning correctly.
