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.

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.
