Connect the Signal Cables for Simplified 1+1 Parallel System

NOTE: The breaker indicator lights are supplied by UPS 1 and will only work while UPS 1 is powered.
NOTE: The AUX switches are in optional parallel installation kit GVSOPT006 provided with the UPS.
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.
  1. Install an AUX switch in the unit input breaker UIB/static switch input breaker SSIB and the maintenance bypass breaker MBB.
    1. Remove the AUX switch cover on the UIB/SSIB and MBB breaker.
    2. Install the AUX switch from kit GVSOPT006 in the UIB/SSIB and MBB breaker.
    3. Connect the non-Class 2/non-SELV signal cables to the AUX switch in the UIB/SSIB and MBB breaker.
    4. Reinstall the AUX switch cover on the UIB/SSIB and MBB breaker.
    5. Only for GVSBPSU80K120H: Fasten the signal cables to the plastic tabs to ensure correct separation from the busbars.

  2. Connect the Class 2/SELV signal cables for the breaker indicator lights from the control terminal block in the maintenance bypass panel to the UPSs as per your configuration.
    NOTE: The breaker 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 breaker indicator light terminals unless it can be confirmed that the circuit is Class 2/SELV.

    NOTICE
    Risk of incorrect equipment behavior
    Cut the preinstalled jumper between pins 8 and 9 on terminal J6618 on board 640-4864 on UPS 2. The 24 V_SELV_OUT cannot be supplied from both UPSs.
    Failure to follow these instructions can result in equipment damage.
  4. Connect the non-Class 2/non-SELV signal cables from the control terminal block in the maintenance bypass panel to the UPSs as per your configuration.
