Control Wires BS1 and BS2
1. A means is required to prevent the TAPS unit from delivering power to the elevator con-
troller when AC power is deliberately shut off at the main disconnect. This is accom-
plished by disabling 24 VDC power to the TAPS-VF board by placing a switch or contact
across terminals BS1 and BS2 on the front of the TAPS connector plate as shown below:
2. Wire the auxiliary contact of the main disconnect between BS1 and BS2 so that, when
the main disconnect is opened, the connection between the two is likewise opened.
Transformer Configuration: 3 kVA Units ONLY
If you have a 6 kVA unit, skip this section. ONLY 3 kVA units require transformer configuration.
Please refer to “Transformer Jumper Schedule, 3 kVA TAPS Units” on page 13

vates.
