Shunt Module Mounting Orientation

Because the shunt module dissipates excess regenerative power in the
form of heat, you need to consider the following guidelines. Refer to
Figure 2.11 and Figure 2.12 for shunt module spacing requirements.
Figure 2.11
Shunt Module Spacing Requirements Within an Enclosure
254 mm (10.0 in.) clearance
for airflow and installation
155 mm (6.1 in.) clearance
for airflow and installation
for signal, power and motor connections
155 mm (6.1 in.) clearance
for airflow and installation
