FR500A&FR510A Series Vector Control Inverter
- 5 -
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 FRECON 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. Rick of electrical hazard.
◆
Do not touches any input/output terminals of inverter with bare
hands. Rick 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.
Maintenance
Danger
◆
Maintenance and inspection can only be performed by
professionals . Risk of personal injury.
◆
Maintain and inspect devices after power is off. Risk of
electric hazard.
◆
Repair or maintain the AC drive only ten minutes after
the AC drive is powered off. This allows for the residual
voltage in the capacitor to discharge to a safe value.
Failure to comply will result in personal injury.
◆
All pluggable components can be inserted or pulled out
only when power has been turned off.
◆
Set and check the parameters again after the AC drive
is replaced.
