Safety and Precautions

Chapter 1 Safety and Precautions
1.1 Safety Precautions
1.1.1 At Wiring
● Wiring must be performed only by qualified personnel under instructions described in this
manual. Failure to comply may result in unexpected accidents.
● A circuit breaker must be used to isolate the power supply and inverter. Failure to comply may
result in a fire.
● Ensure that the power supply is cut off before wiring. Failure to comply may result in electric
shock.
● Connect inverter to ground properly by standard. Failure to comply may result in electric shock.
● Do not connect the input power with output terminals U, V, W, confirm the mark on terminal
before connection to avoid wrong wiring. Failure to comply can damage the inverter!
● Never connect the braking resistor between the DC bus terminals P+ and P-. Failure to comply
may result in a fire.
● The wire size of main circuit should conformed to standard, the wiring should comply with EMC
and local safety standard. Failure to comply may result in accidents.
● Use shielded cable for input output control circuit of analog and rapid speed pulse signal, and
ensure the shielding layer is reliably grounded.
1.1.2 Before Power-on:
● Check that the following requirements are met:
● The voltage class of the power supply is consistent with the rated voltage class of the AC drive.
● The input terminals (R, S, T) and output terminals (U, V, W) are properly connected.
● No short-circuit exists in the peripheral circuit.
● The wiring is secured.
● The external units of inverter and wires are configured under the manual instructed, all matched
circuit and wiring are correctly connected.
● Failure to comply will result in damage to inverter!
1.1.3 After Power-on
● Do not open the cover after inverter power-on to prevent electric shock.
● Do not touch or operate the inverter with wet hands. Failure to comply will result in electric shock.
● Do not touch any terminal of inverter after power-on, or drag connection cable. Failure to comply
will result in equipment damage or electric shock.
● Do not try to check or change the manufacturer parameter. Failure to comply may result in
malfunction or damage to inverter!
● Make sure the mechanical equipment is ready to start before inverter run with loading, make sure
related staff is in safety zone. Failure to comply will result in damage or personal hurt!
● Please pay attention to hiding accident which may result in personal hurt or property damage
while motor is run, if it is necessary to identify the motor parameter.

1.1.4 During Operation
● Do not touch the cooling fan or braking resistor etc, otherwise may cause personal injury!
● Do not do inspection while inverter run, except for professional technician, otherwise may cause
inverter damaged or personal injury.
● Do not move inverter or the installed cabinet while it is run, keep external objects falling into the
device. Failure to comply will result in damage.
● Start/Stop inverter via terminal function or other control method, try not to start inverter via directly
power-on control method. Do not use contactor on inverter output terminal to control motor starting
or stop.
1.1.5 During Maintenance
● Do not repair and maintain the equipment if power is connected. Otherwise there will be danger
of electric shock!
● If the LED is still on light on control panel, it is Disabled to disassemble the body in order to avoid
electric shock.
● The inverter shall be repaired and maintained only by the qualified person who has received
professional training. Otherwise, it may cause personal injury or equipment damage.
● For all the standard equipped or optional accessories, must be dismounted or mounted while the
inverter power is disconnected.
