R EPLACING THE P OWER P LUG
Use the following instructions to replace the four wire plug and socket.
The plug and socket configuration must be rated for at least 240VAC 30A and have a
minimum of four conductors.
The power cord that attaches to the brake has four conductors internally and their
colors are brown, blue, black, and green/yellow.
1
Connect 240VAC single phase power between the brown and the blue wire
connection points.
2 Connect the green/yellow wire to the ground connection point.
3 Wrap the black wire with the white tape to denote that it is a neutral connection
and connect it to the neutral connection point.
4 Refer to the previous table for testing and probe the new connections as follows:
• blue wire as location #2
• brown wire as location #4
• black wire as location #1
• green/yellow wire as location #3.
H ARD W IRING TO THE B UILDING
Use the following instructions to wire the dyno directly to the building.
The brake must connect to a two pole disconnect switch to allow the removal of all
power to the dyno 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 dyno has four conductors internally and their
colors are brown, blue, black, and green/yellow.
1
Remove the brake power plug and connect 240VAC single phase between the
brown and the blue wires through the disconnect switch.
2 Connect the green/yellow wire to the ground connection.
3 Wrap the black wire with white tape to denote that it is a neutral connection and
connect it to the neutral connection.
4 Refer to the previous table for testing and probe the new connections as follows:
• blue wire as location #2
• brown wire as location #4
• black wire as location #1
• green/yellow wire as location #3
