Connect the AC-Power Wires
To connect the ac-power wires to the BCU:
nWARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before ser-
vicing. Follow proper lockout/tagout procedures to ensure the power
can not be inadvertently energized. Failure to disconnect power before
servicing could result in death or serious injury.
1. Lock open the supply-power disconnect switch.
CAUTION
Avoid Equipment Damage!
Be careful when punching out the conduit knockout. Failure to do so
may cause damage to internal components.
2. At the upper left corner of the BCU, punch out either of the
7
/8 in.
(22 mm) 120 Vac knockouts (see Figure 4 on page 17).
3. Access the power supply wiring by removing the BCU cover and the
block-off that covers the power supply area at the top of the BCU.
4. Connect the black 120 Vac hot (or other color wire that is not white or
green) to the top terminal block position (see Figure 6 on page 21).
5. Connect the white 120 Vac neutral wire to the middle terminal block
position.
6. Connect the green ground wire to the bottom terminal block position.
The ground wire should be continuous back to the circuit breaker
panel.
7. On a label, record the location of the circuit breaker panel and the
electrical circuit. Attach the label to the ac-power cover inside the
BCU.
