BCU Mounting and Power Wiring for European Community Installations
BMTW-SVN01F-EN 25
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 22 mm
230 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 blue 230 Vac wire to the top terminal block position (see
Figure 7 on page 26).
5. Connect the brown 230 Vac wire to the bottom terminal block posi-
tion.
6. Connect the green ground wire to the ground lug. 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.
