External Shunt Resistor
Observe these guidelines when mounting your external shunt resistor outside of
the enclosure:
• Mount shunt resistor and wiring in the very dirty zone or in an external
shielded enclosure.
• Mount resistors in a shielded and ventilated enclosure outside of the
cabinet.
• Keep unshielded wiring as short as possible. Keep shunt wiring as flat to
the cabinet as possible.
