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.

Example of Single System with Third-Party Switchgear

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

Install the temperature sensor provided with the UPS in the battery solution. In battery cabinets, 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.

Route the battery temperature sensor cables from the battery solution to the UPS and connect on board 640-4864 in the top of the UPS as shown.

NOTE: One temperature sensor is provided with the UPS. Contact Schneider Electric if you want to buy an additional temperature sensor.

NOTE: The battery temperature sensor cables are considered Class 2/SELV. Class 2/SELV circuits must be isolated from the primary circuitry.
Connect signal cables from the breaker 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 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.

Connect the signal cables from battery breaker 1 in your battery solution for shunt trip or undervoltage (UV) trip connection to board 640-4843 terminal J6603. Follow the illustration for connection with internal or external 24 VDC supply.

24	30	60	20 °C (68 °F)	4 mm² copper	11 AWG copper

The cable supplying the shunt trip shall be a jacket cable and rated for 600 VAC. The specifications and recommendations of the shunt trip manufacturer must always be considered when selecting the cable.

Connect the signal cables from battery breaker 2 (if present) in your battery solution for shunt trip or undervoltage (UV) trip connection to board 640-4843 terminal J6604. The connection principle is the same as for battery breaker 1.

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