- Connect the Class 2/SELV signal cables from the auxiliary products to board 640-4864 in the UPS. Follow the instructions in the auxiliary product manuals.
- Connect the Class 2/SELV signal cables to the input contacts and output relays on board 640-4864 in the UPS.
Do not connect any circuit to the input contacts unless it can be confirmed that the circuit is Class 2/SELV.
Four input contacts are available. Three input contacts can be configured to indicate a given event via the display. The input contacts support 24 VDC 10 mA. All circuits connected must have the same 0 V reference.
