AF-300C GEK-85716
WARNING BURN AND SHOCK HAZARD:
Shut off the AC power supply before making the
output connections. Voltage may be present be-
tween the output terminals even though the
verter Is stopped. Make sure that the “CHARGE
LED indicator has gone out before making any
output connections.
WARNING BURN AND SHOCK HAZARD:
Do not conduct any inspections until after discon-
necting the power supply and after the “CHARGE”
LED indicator on the inverter has gone out.
W A R N I N G MECHANICAL MOTION
HAZARD: When the frequency reference is zero,
Function Code 01 displays zero. If Function Code
13 or 15 contains a non-zero number, the motor will
run when a RUN comand Is glven even If the
frequency reference is zero.
W A R N I N G MECHANICAL MOTION
HAZARD: When running from the Keypad Panel
with the ‘Local/Remote” switch the “Local” posi-
tion, pressing the FWD or REV key will cause the
motor to rotate. Any RUN permissives that may be
wired to the FWD or REV terminals are ignored.
WARNING PERSONAL INJURY HAZARD:
To prevent personal or equipment damage
caused by equipment malfunction, only adequately
trained persons should modify any programmable
inverter.
WARNING FIRE HAZARD: Use
namic braking resistors that are provided by GE
Drive Systems. These are special resistors that
have a thermal fuse built in that opens if the
resistor gets too hot. This fuse should only open
If the DB transistor In the lnverter or DB unit fails
short circuited. The resistor will need to be re-
placed if this happens.
CAUTION: When removinn or wires,
handle them the connector onlv and not bv the
wire itself. Be careful not to mix wires when
them.
CAUTION: Do not connect power to the
output terminals V, Connect power supply
onlv to the power terminal; , L2,
CAUTION: Do not connect power to the
brakina resistor connection terminals Never
short-circuit between P-N or P-DB terminals, and do
not connect
resistance with a resistance value
less than the standard application brakina resistor.
CAUTION: Do not connect power to the
control circuit terminals (except B,
CAUTION: For RUN and STOP, use the FWD-CM
and REV-CM (reverse) terminals. Do not
use a contactor (for on the line
side of the inverter for RUN and STOP.
CAUTION: Do not use a contactor on the output
side of the inverter for ON/OFF operation.
CAUTION: The AC Power Transformer
KVA ratina should be than 1.5 times the
Horsepower ratina of the invetter, but not areater
than 500
If an AC Power Transformer
greater than 500 is to be used, install a line
reactor (optional; must be pruchased on
the line side of the inverter. A Line Reactor is also
required if an SCR Tvpe controller and/or Power
Factor Correction Capacitors are used on the same
power lines.
CAUTION: Do not connect filter capacitors on the
output side of the invetter.
CAUTION: Do not operate the inverter without the
ground wire connected.
CAUTION: If the inverter’s fault alarm is activated,
consult the TROUBLESHOOTING section of this
instruction book, and after the problem,
resume operation. Do not reset the fault alarm
bv external etc.
CAUTION: Do not perform a meaaer test between
the inverter terminals or on the control circuit terminals.
CAUTION: Do not connect power voltage
that exceeds the standard specification
fluctuation permissible. excessive voltaae is applied
to the invetter,
to the internal components
will result.
