Installing Your 8720MC Drive 1-21
When mounting your active shunt module inside the enclosure,
follow these additional guidelines (refer to Figure 1.10 for an
example).
• Metal-clad modules can be mounted anywhere in the dirty zone,
but as close to the 8720MC as possible
• Shunt power wires can be run with motor power cables.
• Separate shunt power cables from other sensitive, low voltage
signal cables.
