Installation Guide

1. Power Down: Completely de-energize the UR relay chassis. Never install or remove modules while energized.
2. ESD Protection: Wear a grounded electrostatic discharge (ESD) wrist strap before handling the module.
3. Slot Verification: Confirm the target slot is empty and matches the module's physical orientation.
4. Module Insertion: Slide the UR-7JV into the chassis guide rails, aligning the rear terminal block with the backplane connector. Push firmly until the faceplate sits flush.
5. Secure Mounting: Tighten the faceplate retention screws to the specified torque.
6. Wiring: Connect field wiring per the UR series wiring diagram. Observe correct polarity for all connections.
7. Configuration: Power on the relay and configure protection settings via EnerVista UR Setup software or the front panel keypad/LCD.
