Power Wiring Procedure
The following procedure provides the steps needed to properly perform the
power wiring connections to the 1395 drive.
Using Table 4.D, verify that the motor field is compatible with the DC field
voltage output of the drive.

1. Connect the motor armature and field leads to produce proper direction
of motor rotation. Table 4.E lists the connections required to produce
counterclockwise rotation of the motor when viewed from the
commutator end with a positive speed reference input to the drive.

2. The 1395 is supplied with semi-conductor fuses for bridge protection.
A line reactor must be used between the main distribution system and
the drive. An isolation transformer can also be used. Refer to
Figure 4.4 for AC input wiring at the main fuses.
Connect incoming three-phase AC line power to the AC Input Circuit
Breaker.
