Installation & Maintenance Guide

Turn off power before connecting or disconnecting the 1794-CE3 cable. Align the connector with the port on the terminal base. Push the connector firmly until it clicks into place. Do not force the connection if resistance is felt.

Route the cable away from high-voltage lines and noise sources. Use cable ties to secure the cable and prevent strain. Avoid sharp bends that could damage the internal wires. The minimum bend radius should be followed as per standard practice.

Periodically inspect the cable for cuts or abrasions. Replace the cable if any damage is found. Keep the connectors clean and free from debris. Do not expose the cable to chemicals or solvents. Store the cable in a dry, static-free environment when not in use.
