Installing Power Wiring

6-7

6.3.2 Installing Branch Circuit Protection

Install the required branch circuit protection according to the
applicable local, national, and international codes (such as
NEC/CEC). The fuses or approved circuit breaker must be installed
in the line before the drive input terminals. Fuse and circuit breaker
values are provided in tables 4.5 through 4.7.

6.3.3 Installing the Required External/Separate Input

Disconnect

An input disconnect must be installed in the line before the drive
input terminals in accordance with local, national, and international
codes, such as NEC/CEC. The disconnect should be sized
according to the in-rush current as well as any additional loads the
disconnect might supply. The trip rating for the in-rush current (10 to
12 times full load current) should be coordinated with that of the
input isolation transformer, if used.

6.3.4 Installing Power Wiring from the AC Input Line

to the Drive’s Power Terminals

To connect AC input power to the drive:

Step 1.

Wire the AC input power leads by routing them according
to drive type. Refer to figure 5.1. Maximum power wiring
sizes are listed in table 4.2.

Step 2.

Connect the three-phase AC input power leads to the
appropriate terminals. Connect the AC input power leads
to terminals R/L1, S/L2, T/L3 on the power terminal block.

Step 3.

Tighten the AC input power terminals to the proper torque
as shown in table 6.1

!

ATTENTION: Most codes require that upstream branch
protection be provided to protect input power wiring. Failure
to observe this precaution could result in severe bodily injury
or loss of life.

!

ATTENTION: Protect the contents of the cabinet from metal
chips and other debris while drilling the conduit openings.
Failure to observe this precaution could result in damage to,
or destruction of, the equipment.

ATTENTION: 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.
