Using the Relay Terminal Block Appendix C
11. Turn ON the power supply to the new Unit. (The power supply to other nodes should still be ON.)
Note 1. Signal will still be flowing through the communications cables during the replacement procedure if the
network is still operating. Use an insulated screwdriver and be very sure that the metal portions
of the Relay Terminal Block or the communications cable crimp terminals do not come into con-
tact with any conductive material.
2. Replace the Unit only after confirming that doing so will not affect the system, including the affects of
separated nodes or communications errors.
3. Always turn OFF the power supply to all nodes when connecting communications cables to or remov-
ing them from the Relay Terminal Unit.
