Installation

l Preparation:

Ensure that all power sources are disconnected before installation to avoid electrical hazards.

Gather the necessary tools, including a screwdriver, to secure the cable.

l Mounting the Cable:

Identify the locations of the two 1757-SRM modules that will be connected using the cable.

Ensure the cable routing does not interfere with other equipment or create tripping hazards.

l Connecting the Cable:

Insert one end of the 1757-SRC1 cable into the ST-type connector on the first SRM module.

Securely connect the other end of the cable to the second SRM module, ensuring a snug fit to prevent signal loss.

l Final Checks:

Inspect all connections for secure fittings and verify that there is no visible damage to the cable.

Ensure that any cable management practices are followed to maintain organization and safety.

l Power Up:

Restore power to the system and monitor the communication status between the redundancy modules to confirm proper operation.
