Circuit Board Jumper Connections
There are several jumpers located on different boards in the 1395 that are
used to configure the drive for a specific application.
1. Verify that the motor field current jumper, is in the proper location per
Table 4.F. Obtain the motor full field current data from the motor
nameplate. The position of the jumper is determined by both the drive
current rating and DC shunt field current rating. Use the drive current
rating to select the column in Table 4.F and the field current to select
the field current jumper position.

2. Verify that the voltage selection for the Reset and Motor Thermostat
inputs is correct. Jumpers J11 and J12 on the Power Stage Interface
Board determine whether the voltage used for the Reset and Motor
Thermostat inputs is 24VDC or 115VAC. Both switches should be in
the same position (See Table 4.G).
