Wiring
Danger
◆
Wiring must be performed by authorized and qualified
personnel. Risk of danger.
◆
Circuit-breaker should be installed between inverter and the
mains. Risk of fire.
◆
Make sure the input power supply has been completely
disconnected before wiring. Failure to comply may result in
personnel injury and/or equipment damage.
◆
Since overall leakage current of this equipment may be bigger
than 3.5mA, for safety's sake, this equipment and its associated
motor must be well grounded so as to avoid risk of electric
shock.
◆
Never connect the power cables to the output terminals (U/T1,
V/T2, W/T3) of the AC drive. Pay attention to the marks of the
wiring terminals and ensure correct wiring. Failure to comply will
result in damage to the AC drive.
◆
Install braking resistors at terminals (+)and PB only. Failure to
comply may result in equipment damage.
◆
AC 220V signal is prohibited from connecting to other
terminals than control terminals R1A, R1B, R1C andR2A, R2B,
R2C. Failure to comply may result in equipment damage.
Caution
◆
Since all adjustable frequency AC drives from CG have been
subjected to hi-pot test before delivery, users are prohibited from
implementing such a test on this equipment. Failure to comply
may result in equipment damage.
◆
Signal wires should to the best of the possibility be away from
main power lines. If this cannot be ensured, vertical
cross-arrangement shall be implemented, otherwise interference
noise to control signal may occur.
◆
If motor cables are longer than 100m, it is recommended
output AC reactor be used. Failure to comply may result in faults.
Before
Power-on
Danger
◆
Inverter shall be power-on only after the front cover is
assembled. Risk of electrical hazard.
Caution
◆
Verify that the input voltage is identical to the rated voltage of
product, correct wiring of input terminals R/L1, S/L2, and T/L3
and output terminals U/T1, V/T2, and W/T3, wiring of inverter
and its peripheral circuits, and all wires should be in good
connection. Risk of inverter damage.
After Power-on
Danger
◆
Do not open the cover after power. Risk of electrical hazard.
◆
Do not touches any input/output terminals of inverter with bare
hands. Risk of electrical hazard.
Caution
◆
If auto tuning is required, be careful of personal injury when
motor is running. Risk of accident.
◆
Do not change the defaults of parameters. Risk of devices
damage.
During
Operation
Danger
◆
Non-professionals shall not detect signals during operation.
Risk of personal injury or device damage.
◆
Do not touch the fan or the discharging resistor to check the
temperature. Failure to comply will result in personal burnt.
Caution
◆
Prevent any foreign items from being left in the devices during
operation. Risk of device damage.
◆
Do not control start/stop of inverter by ON/OFF of contactor.
Risk of device damage.
