Installation Guidelines
This chapter describes how to install the Power Module and connect it to the UDC, the
rail I/O, the drive I/O, and the resolver.
For connection instructions specific to your system, refer to the detailed prints
included in the instruction book shipped with each engineered drive system.
4.1 Wiring and Grounding
To reduce the possibility of electrical noise interfering with the proper operation of the
drive system, exercise care when installing the wiring between the system and
external devices. For detailed recommendations, refer to IEEE 518.
The grounding stud (GND) on the Power Module must be connected to the grounding
stud on the DC Bus Supply, as shown in figure 4.2. The DC Bus Supply must be
connected to earth ground (PE) and checked with an ohmmeter before power is
applied.
4.2 Power Module Installation
The following procedure is intended to be only a guide to assist you in installing the
Power Module. Refer to the wiring diagrams supplied with your system for more
specific information. Note that there are no user-adjustable potentiometers or jumpers
on the Power Module.
Before installation, ensure that ambient air around the Power Module is clean, dry, and
free of flammable or combustible vapors, chemical fumes, oil vapor, steam, and
excessive moisture and dirt.

ATTENTION: Only qualified personnel familiar with the construction and
operation of this equipment and the hazards involved should install,
adjust, operate, or service this equipment. Read and understand this
manual and other applicable manuals in their entirety before proceeding.
Failure to observe this precaution could result in severe bodily injury or
loss of life.
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power from the
DC bus supply, wait five (5) minutes and then measure the voltage at the
POS and NEG terminals of the DC bus supply and each Power Module
to ensure the DC bus capacitors are discharged before touching any
internal components. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming with all applicable
local, national, and international codes. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
