Securing the Passive Shunt Module
The following procedure assumes you have prepared your mounting
panel. To mount your passive shunt module:
1. Install the top two mounting fasteners on the sub panel for the
shunt module. Refer to Product Specifications on page 7 for
mounting hardware specifications.
2. Mount the shunt module on the two fasteners.
3. Install the lower fastener.
4. Tighten all mounting fasteners.
Wiring the Passive Shunt Module to a Drive
90° C (194° F), 600V, 2.5 mm2 (14 AWG) copper wire is supplied with
the shunt. The maximum length of the wire should be 914.4 mm (36.0
in.).
Two recommended methods for wiring to reduce EMI noise can be
used to connect the passive shunt module with your drive:
• Twisted conductors (2 twists per foot minimum) with ferrite filters,
• Shield the shunt-to-drive wiring by enclosing in grounded metal
conduit.
Always keep unshielded wiring as short as possible. When shielding is
used, the shield must be grounded to the shunt and drive chassis
ground as is the motor power cable.
ATTENTION
!
DC bus capacitors may retain hazardous voltages
after input power has been removed, but will
normally discharge in several seconds.
Before working on the drive, measure the DC bus
voltage to verify it has reached a safe level or wait a
full 5 minutes to ensure that all voltages on the
system bus have discharged.
Failure to observe this precaution could result in
severe bodily injury or loss of life.
