4. Connect the power harness to the input/output connectors on the UPS.
5. If desired, wire the 7-position dry relay connector. Recommended wire strip length is 7mm, with a
max torque of 5Lb-in. as shown in Fig 4-2 for reporting to the traffic controller.
Fig. 4-2 7-position connector wiring example
When using the 7-position MAINS/GEN sense relay connector, please note operation as follows:
1. The first 2 positions on the left of the connector labeled “AUX’ are intended for use with UPS systems
that have external control wires to operate that system’s respective transfer switch. These two posi-
tions are to be used to safely secure those wires. The control wires will not be used by the SATS.
2. Positions 3 and 4 are used to report the presence of AC utility line power. When AC utility line volt-
age is present, the dry relay contacts of these 2 positions will close. When AC utility line voltage is
absent, the dry relay contacts will open.
3. Positions 5 and 6 are used to report the presence of AC Generator power. When AC Generator volt-
age is present, the dry relay contacts of these 2 positions will close. When AC Generator voltage is
absent, the dry relay contacts will open.
4. Position 7 is an additional grounding point.
