Control Circuit Wiring; Main Circuit Wiring - GE Fuji Electric AF-300 MICRO-SAVER II Instructions Manual

Control Circuit Wiring

Drive is wired at shipment for operation and frequency
setting through the keypad panel (frequency is set at 60
Hz.)
– See Figure 4-2, and 4-4 for wiring connections.
– See TABLE 5 for description of all terminals.
Make wire connections as shown in Figure 4-4 through 4-6
for desired mode of external operation through Control
Circuit Terminals.
CAUTION
: The Control Circuit Terminal wiring should be
kept as far away as possible from the main power wiring to
prevent operational error due to noise interference. Never
install both types of wiring in the same duct or conduit. (A
separation distance of 4 inches [10 centimeters] or more is
recommended.) If the control circuit wiring must cross the
main power wiring, it should cross at a right angle.
CAUTION
: Use shielded or twisted wire for the control
circuit wiring (wiring should be as short as possible, i.e. 65
feet or less [20 meters.]) Connect outer covering of the
shielded wires to the Drive ground terminal and leave the
other end open, but taped with electrical insulating tape.

CAUTION
: Install a suppressor in parallel with any relay or
solenoid type coil as shown above, that may be close to the
Drive to prevent noise from causing erratic Drive operation.

Main Circuit Wiring

CAUTION:
Be sure that the power supply is never
connected to the U, V, W terminals or the P (1), P (+),
DB terminals.
1. Connect the ground terminal as shown in the appro-
priate view of Figure 4-3. (Do not operate without
the unit being grounded.)
— The ground wire must be minimum 14 AWG
and short as possible
2. Connect the power supply wires to the L1, L2, and
L3 terminals of the Main Circuit Terminal Block as
shown in the appropriate view of Figure 4-3. (See
TABLE 5 for description of all terminals and TABLE
4 for recommended wire sizes.) Note that L1 and L2
terminals only, are available on single phase input
models.
NOTE: Motor will rotate counterclockwise when viewed from
the shaft end when connected normally. If the motor rotates in
reverse direction, interchange any two of the U, V, or W terminal
connections.

3. Connect the 3-phase motor wires to the U, V, and
W terminals of the Main Circuit Terminal Block as
shown in the appropriate view of Figure 4-3. (See
TABLE 5 for description of all terminals and TABLE
4 for recommended wire sizes.)
4. Suitable for use on a circuit capable of delivering not
more than 1000A (1 HP or less) or 5000A (2 HP or
more) RMS symmetrical.
5. AC input fuses are to be customer supplied and may
be branch circuit protection fuses. The maximum
allowance fuse rating per TABLE 4.
