WARNING
Do not touch circuit components until main input power has been
turned off and "CHARGE" lamp is extinguished. The capacitors
are still charged for up to 5 minutes and can be quite dangerous.
Do not connect or disconnect wires and connectors while power is
applied to the circuit.
CAUTION
The GPD 333 leaves the factory with constants initialized for
external 2-Wire control and constant
no–00 set to 01 . Before
using either initialization function of this constant, know your con-
trol wiring configuration :
08 = Factory 2-Wire control initialization ( maintained Run contact )
09 = Factory 3-Wire control initialization ( momentary Start /Stop input )
Entering either initialization code returns all constants to factory
settings, and automatically returns constant
no-00 setting to 01 .
If the GPD 333 is connected for 3-Wire control and this constant is
set to 08 ( 2-Wire control initialization ), the motor may run in
reverse direction WITHOUT A RUN COMMAND APPLIED.
Equipment damage or personal injury may result.
Constant
no-03 must be set for the proper motor voltage. Drive
leaves factory with this constant set for 230.0 or 460.0 volts.
CAUTION
Always ground the GPD 333 using ground terminal G ( E ). See
paragraph 1.4.2 "Grounding".
Never connect main circuit output terminals T1 ( U ), T2 ( V ) &
T3 ( W ) to AC main circuit power supply.
CAUTION
Do not perform a withstanding voltage test on any part of the
GPD 333. Equipment uses semi-conductors and is vulnerable to
high voltage.
The Control PC board employs CMOS ICs which are easily dam-
aged by static electricity. Use proper electrostatic discharge
(ESD) procedures when handling the Control PC board.
