5.3 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 inĆrush current as well as any

additional loads the disconnect might supply. Note that the trip rating for the inrush current (10Ć12

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 AĆC Input Line to the Drive's Power

Terminals

Use the following steps to connect AĆC input power to the drive:
Step 1. Wire the AĆC 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 1Ć5 HP drives, route the power leads through the bottom right opening of the drive base.
On 7.5Ć25 HP drives, route the power leads through the bottom middleĆright opening of the

drive base. If the snubber resistor braking option is used, route the power leads through the

bottom right opening.
On 25Ć60 HP drives, route the power leads through top right or bottom right openings of the

drive base.
On 60Ć100 HP drives, route the power leads through the bottom left opening of the cover.
On 100Ć150 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 threeĆphase AĆC input power leads (threeĆwire 380Ć460 VAC) to the proper

terminals according to drive type.
On 1Ć60 HP drives, connect the AĆC input power leads to terminals R/L1, S/L2, T/L3 on the

power terminal strip.
On 60Ć150 HP drives, connect the AĆC input power leads to terminals 1L1, 1L2, and 1L3.

Step 3. Tighten the AĆC input power terminals to the proper torque as shown in table 5.1.
