Connect the Signal Cables from Switchgear and Third-Party Auxiliary Products

NOTE: Route the signal cables separately from the power cables and route the Class 2/SELV cables separately from the non-Class 2/non-SELV cables.

NOTE: IMB* cannot be used in a system with an external MBB and IMB* must be padlocked in the open position.

Connect signal cables from the disconnect device indicator lights in your switchgear to board 640-4864 terminal J6618 in the top of the UPS. If an external supply is used, remove jumper from J6618 pin 8 and 9.

NOTE: The disconnect device indicator light circuit is considered Class 2/SELV. Class 2/SELV circuits must be isolated from the primary circuitry. Do not connect any circuit to the disconnect device indicator light terminals unless it can be confirmed that the circuit is Class 2/SELV.

Connect signal cables from AUX switches in your switchgear to board 640-4843 in the top of the UPS.
