Rockwell Automation GV3000/SE AC Bookshelf Drive Hardware Ref, Installation, and Troubleshooting - Manual (Page 46)

5-2 GV3000/SE AC Bookshelf Drive Hardware Reference, Version 6.06
For drives not equipped with an AC Mains Filter, the maximum line distribution system
capacity is 315 KVA, three-phase with 10,000 amps symmetrical fault current capacity
with a line impedance of less than 5%.
5.2 Installing Fuses for Branch Circuit Protection
Install the required, user-supplied branch circuit protection fuses according to the
applicable local, national, and international codes (e.g., NEC/CEC). The fuses must
be installed in the line before the drive input terminals. See figure 5.1. Fuse value
selections are provided in table 3.10.
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 local, national, and international codes (e.g., 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 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 AC Input Line to the
Drive’s Power Terminals
Use the following steps 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 figures 4.1, 4.2, or 4.3. Tables 3.5 and 3.6 contain the recommended
power wiring sizes.
Step 2. Connect the three-phase AC input power leads (three-wire 380-460 VAC) to
terminals L1, L2, L3.
Step 3. Tighten the AC input power terminals to 1.4 Nm (12 in-lb).
!
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: 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.
