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

CAUTION
Risk of equipment damage
All Class 2/SELV signal cables shall be double insulated cables and minimum rated for 30 VDC. All non-Class 2/non-SELV signal cables shall be double insulated cables and minimum rated for 600 VAC.
Failure to follow these instructions can result in injury or equipment damage.

Recommended Signal Cable Size

Distance from UPS to equipment Recommended signal cable size
0-50 m 0.5 mm2
50-100 m 0.75 mm2
100-200 m 1 mm2

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 the temperature sensor(s) 0M-1160 provided with the UPS in the battery solution. Follow the instructions provided with your battery solution to place the temperature sensor in the battery solution. If nothing is specified, install the temperature sensor in the top corner of the battery cabinet.
    WARNING
    Hazard of fire
    Position the temperature sensor as described to ensure correct temperature measurements.
    Failure to follow these instructions can result in death, serious injury, or equipment damage.
  2. Route the battery temperature sensor cables from the battery solution to the UPS and connect as shown.
    NOTE: Two temperature sensors 0M-1160 are provided with the UPS.
    NOTE: The battery temperature sensor cables are considered Class 2/SELV. Class 2/SELV circuits must be isolated from the primary circuitry.
  3. Connect signal cables from the disconnect device indicator lights in your switchgear to terminal J6605 in the UPS.
    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.
  4. Connect the non-Class 2/non-SELV signal cables from the battery disconnect device(s) in your battery solution for shunt trip or undervoltage (UV) trip connection to the UPS. Follow the illustration for connection with internal 24 VDC supply. The UPS can connect to and monitor up to four battery disconnect devices.
    1. Connect the signal cables from battery disconnect device 1 to terminal J6614, 1-5 in the UPS.
    2. Connect the signal cables from battery disconnect device 2 to terminal J6614, 6-10 in the UPS.
    3. Connect the signal cables from battery disconnect device 3 to terminal J6615, 1-5 in the UPS.
    4. Connect the signal cables from battery disconnect device 4 to terminal J6615, 6-10 in the UPS.

    J6611, 4 and 8 UOB (unit output disconnect device) Connect to normally open (NO) AUX switch in unit output disconnect device UOB.
    J6611, 2 and 6 SSIB (static switch input disconnect device) Connect to normally open (NO) AUX switch in static switch input disconnect device SSIB. SSIB must contain an AUX switch for each connected UPS.
    J6611, 1 and 5 UIB (unit input disconnect device) Connect to normally open (NO) AUX switch in unit input disconnect device UIB. UIB must contain an AUX switch for each connected UPS.
    J6611, 3 and 7 MBB (maintenance bypass disconnect device) Connect to normally closed (NC) AUX switch in maintenance bypass disconnect device MBB. MBB must contain an AUX switch for each connected UPS.
    J6610, 1-8 EXT BF (external backfeed disconnect device) See Backfeed Protection.
  6. Only for solenoid key release unit (SKRU): Connect signal cables from the solenoid key release unit in your switchgear to the UPS.
    1. Connect the signal cables between the solenoid key release unit and the UPS terminal J6601, as shown.
    2. Add a jumper between pin 3 and 5 in J6601.
    NOTE: SKRU presence must be configured by Schneider Electric Services Representatives at start-up.
