Installing Power Wiring 5-5
5.4.2 Installing Branch Circuit Protection
Install the required branch circuit protection fuses 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 values are
provided in tables 4.4 through 4.7.
5.4.3 Installing the Required 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
.
5.4.4 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.
Connect the AC input power leads to terminals R/L1, S/L2, T/L3 on the power
terminal block (see figure 5.2).
Step 2. Tighten the AC input power terminals to the proper torque as shown in table
5.2.
!
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.
