Controls Installation
Improper grounding or voltage in circuits
connected to the CIM can lead to component
failures. In particular, the interlock and analog
output circuits are sensitive to improperly
connected external circuits.
Prior to connecting the control wiring to the
CIM, check for improper grounding; it can be
identified by measuring the voltage between the
customer’s negative terminals and the ground
(J1 COM or Modbus shield) terminal on the CIM.
If the measured voltage is not zero, determine
the source of the voltage. The most likely cause
of voltage is insufficient insulation of the external
circuit. In case of uncertainty of the grounding,
connect the negative terminals of the external
circuit to a ground and then connect the external
ground to the ground on the CIM.
Figure 44 Illustrates the power and control
interface cables to input and output of the
drive module. The cables must be installed so
that a minimum distance of 20 mm (7/8") exists
between each cable harness to the other, see
Figure 46.
