Installing Input Power Wiring

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. Tables 3.3 and 3.4 contain the recommended

power wiring sizes.

ATTENTION: Do not route signal and control wiring in the same
conduit with power wiring. 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 three-phase AC input power leads (three-wire 200-230 VAC)

to terminals R/L1, S/L2, T/L3. Refer to figure 4.1 for the locations of the
terminal.

Step 3. Tighten the AC input power terminals to 9.8-11.7 Newton-meters (87-104

lb-in) for 30-100 HP drives.

5.5 Installing Power Wiring from an External DC Bus to the

Drive's Internal DC Bus Terminals

Use the following steps to connect DC input power to the drive:

Step 1. Wire the DC input power leads. Tables 3.3 and 3.4 contain the recommended

power wiring sizes.

ATTENTION: Do not route signal and control wiring in the same
conduit with power wiring. This can cause interference with drive
operation. Failure to observe this precaution could result in damage
to, or destruction of, the equipment.

ATTENTION: If the GV3000/SE drive is connected to an external DC
bus, the user is responsible for DC bus short-circuit protection. Failure
to observe this precaution could result in damage to, or destruction of,
the equipment.

Step 2. Connect the DC input power leads (two-wire 310 VDC nominal) to

terminals + and –. See figure 4.1 for the locations of the terminals.

Note that the maximum discharge rate of the DC bus supply should be 200
V/second.

Step 3. Tighten the DC input power terminals to 9.8-11.7 Newton-meters (87-104

lb-in) for 30-100 HP drives.
