Use the following instructions to wire the brake directly to the building.
The brake must connect to a two pole disconnect switch to allow the removal of all
power to the brake for servicing. This box may contain fusing, circuit breakers, or the
circuit protection may be upstream in the building power system. The circuit must be
protected to 30A with slow blow fuses or time delayed circuit breakers.
The power cord that attaches to the brake has three conductors internally and their
colors are white, black, and green.

Remove the brake power plug and connect 240VAC single-phase between the
black and the white wires through the disconnect switch.
2 Connect the green wire to the ground connection.

• white wire as location #2
• black wire as location #4
