Task: Rectifier Checks
To determine if a rectier has been damaged use a multimeter
to check resistance. Refer to internal wiring diagram, Figure 2
on page 3. Check the following lead combinations by placing
the positive clip on one lead and the negative clip on the other.
See Table 1.
Table 1
(+) (-) Resistance
B1 B4 Low
B4 B1 High
B1 B3 High
B3 B1 Low
B2 B4 Low
B4 B2 High
B2 B3 High
B3 B2 Low
If any resistance is measured low where it should be high or
vice versa, the rectier has been damaged and replacement
rectier kit (p/n 024018) should be purchased.

ELECTRICAL CONNECTIONS:
Warning:
The user is responsible for conforming with the National
Electrical Code and all other application local codes.
Wiring practices, grounding, disconnects and overcurrent
protection are of particular importance. Failure to observe
these precautions could result in severe bodily injury or
loss of life.
Caution:
Since the brake is internally wired to the motor, be sure
that the lead wires are not frayed. Failure to observe this
precaution could result in damage to or destruction of the
equipment.
Caution:
If electrical soft-start or inverter is used in the system care
must be taken to ensure that the brake is supplied with full
voltage. Brake must have the full input voltage to ensure
proper release and operation.
Caution:
Replacement/Retrofit Applications: To ensure proper
wiring connections when placing this brake in place of
another, be sure to trace motor leads back to the motor
conduit box. Brake lead markings may differ among brake
manufacturers. If in doubt, voltages should be measured.
Refer to Table 3 for standard brake connections for separately
connected Short Series brakes.
