Installing a Required External/Separate Input Disconnect

An input disconnect must be installed in the line before the drive input terminals in accordance with
NEC/CEC guidelines. The disconnect should be sized according to the in rush current as well as any
additional loads the disconnect might supply. Note that the trip rating for the inrush current (10 12
times full load current) should be coordinated with that of the input isolation transformer, if used.
Refer to section 5.1 for additional information.
5.4 Installing Power Wiring from the A C Input Line to the Drive's Power
Terminals
Use the following steps to connect A C input power to the drive:
Step 1. Wire the A C input power leads by routing them according to drive type. Refer to figures 4.1
through 4.6. Tables 3.3 through 3.7 contain the recommended power wiring sizes.
On 1 5 HP drives, route the power leads through the bottom right opening of the drive base.
On 7.5 25 HP drives, route the power leads through the bottom middle right opening of the
drive base. If the snubber resistor braking option is used, route the power leads through the
bottom right opening.
On 25 60 HP drives, route the power leads through top right or bottom right openings of the
drive base.
On 60 100 HP drives, route the power leads through the bottom left opening of the cover.
On 100 150 HP drives, route the power leads through the top left opening of the cover.
CAUTION: Do not route signal and control wiring with power wiring in the same conduit. This can cause
interference with drive operation. Failure to observe this precaution could result in damage to or destruction
of the equipment.
Step 2. Connect the three phase A C input power leads (three wire 380 460 VAC) to the proper
terminals according to drive type.
On 1 60 HP drives, connect the A C input power leads to terminals R/L1, S/L2, T/L3 on the
power terminal strip.
On 60 150 HP drives, connect the A C input power leads to terminals 1L1, 1L2, and 1L3.
Step 3. Tighten the A C input power terminals to the proper torque as shown in table 5.1.
