6.3.2 Installing Fuses for 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
table 4.3.
6.3.3 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.
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 4.1.
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
(see figure 6.2).
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.
