Branch Circuit Protection; Fuse/Circuit Breaker And Wire Sizing - Franklin Electric SUBDRIVE UTILITY UT3P Manuel Du Propriétaire

Risk of damage to drive
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 behaviors.
• Do not run input power and motor wires in the same conduit.
• Do not run motor wires from multiple drives 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 drive wiring parallel with house or out-building wiring.
• Do not use aluminum wires for drive connections.
• Do not use with a Ground Fault Circuit Interrupter (GFCI) between breaker panel and motor.
• 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 protec-
tion 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 maxi-
mum 300% of full load motor output current rating as noted below.

Note: Drive minimum breaker amps may be lower than AIM Manual specifications because of the soft-start-
ing characteristic of the drive.
Wire Sizing
Note: The drive terminal blocks are rated to accept 6AWG – 20AWG (both input and output wiring).
6AWG is the maximum wire size the drive can physically accept. An external junction box is required if using
larger wire (i.e. you can use 4AWG or bigger cable out to the motor, but you will have to junction and splice
this to 6AWG or smaller before entering the drive enclosure).
