INSTALLATION AND SETUP
Electrical Installation
Risk of damage to VFD
Follow all wire routing and grounding instructions carefully. Inductive currents caused by parallel
wiring, or close proximity between high voltage and control wiring can cause unexpected behav-
iors.
• Do not run input power and motor wires in the same conduit.
• Do not run motor wires from multiple VFDs in common conduit.
• Do not run control wiring parallel with high voltage wiring.
• Do not install a magnetic contactor or disconnect in the motor circuit.
• Do not run VFD wiring parallel with house or out-building wiring.
• Do not use aluminum wires for VFD connections.
• Do not use with a Ground Fault Circuit Interrupter (GFCI).
• All wiring must comply with the National Electrical Code and local codes.
• Improper splicing or damage to motor cable insulation may expose the conductor(s) to
moisture and can produce motor cable failure.
Branch Circuit Protection
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with the National Electrical Code and any additional
local codes, or the equivalent. Drive shall be protected by fuse or inverse-time circuit breaker only,
rated 300 V, and a maximum 300% of full load motor output current rating as noted in the table
below.

Notes:
• MonoDrive minimum breaker amps may be lower than AIM Manual specifications because of
the soft-starting characteristic of the drive.
• SubDrive minimum breaker amps may exceed AIM Manual specifications because the drive is
supplied from single-phase service rather than three-phase.
