Installation
Figure 11: Typical Three-Phase 230VAC (FX-490 through FX-6120)
Failure to follow safe installation guidelines can cause death or serious injury. To insure
proper operation after a power down you should wait a minimum of ten seconds before
reapplication of power. If logic and bridge AC power are wired separately, the AC power
must always be applied to the logic terminals BEFORE the bridge terminals.
FX-6200 through FX-8400
The FX-6200 through FX-8400 Amplifiers are designed to operate on a 50/60 Hz, three phase
AC power line. The AC voltage of this power line must be within 196 to 264VAC and be free
of voltage transients which exceed this range. If you find that your AC power does not meet
these specifications, AC line conditioning is required. Wire sizing and transformer selection
should be done carefully.
The AC input lines are connected to the amplifier by means of terminal blocks located on the
bottom plate of the drive.
An external AC voltage of 196 to 264VAC single phase for separate logic power can be
connected to the AUX AC power input terminals (L1, L2 and GND). For these applications
the main/auxiliary switch must be switched to the AUX position before applying power.
If separate logic power is connected, then the logic AC power is separated from the high
power circuits that create the motor +BUS voltage. The AC power supply voltage can now be
removed from the three phase L1/L2/L3 and GND terminals, without removing logic power.
