Plan the Kinetix 5700 Drive System Installation Chapter 2
Observe these guidelines when mounting your external active shunt inside the
drive system enclosure:
• Mount the shunt resistors anywhere in the dirty zone, but as close to the
Kinetix 5700 power supply as possible.
• Route the shunt power wires with other very dirty wires.
• 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.
• Separate shunt power cables from other sensitive low-voltage signal
cables.
