Figure 40 - External Shunt Resistor Mounted Inside the Drive System Enclosure
External Active Shunt Modules
Observe these guidelines when mounting external active shunt outside the
drive system enclosure:
• Mount the shunt module so that wiring routes in the very dirty zone
inside the drive system enclosure.
• Keep unshielded wiring as short as possible, not to exceed 3 m (9.8 ft).
Keep shunt wiring as flat to the cabinet as possible.
