HD30/HD3N/HD50 Series
Simple Manual
A Danger Information which is Critical for Avoiding Safety Hazard
• Electrical installation must be performed by a qualified electrical
engineer and maintained by a professionally trained and authorized
professional.
• The inverter should be installed on a flame-retardant object such as
metal, away from flammable and explosive objects.
• After the inverter is powered o for 10 minutes, confirm that the
internal charge indicator is o and the voltage between the power
terminals (+) and (-) is lower than 36V, only then can operate.
• After the external power emergency stop terminal is turned on, be
sure to confirm that its action is eective and reliable.
• The inverter has a leakage current greater than 3mA to the ground.
The specific value is determined by the use conditions. The inverter
and the motor must use two independent grounding wires to ensure
safety. It is also recommended that users install Type B leakage
protection devices (ELCB/RCD).
• Before starting the motor and mechanical equipment, please make
sure that the motor and mechanical equipment are working within
the allowable range.
• Please note that do not touch the inverter terminals when the inverter
is powered. Do not connect the power terminals of the inverter to the
product housing, and do not short-circuit the power terminals.
• When the operating environment exceeds 40℃ , the inverter needs to
be derated. For every 1℃ increase, it needs to be derated by 2%. The
Max. working environment temperature is 50℃ .
• When the altitude exceeds 1000 meters, derating is required.
Danger
Warning
A Warning Information which is Critical for Avoiding Damage to the
Product and other Device
• Do not drop wires, screws, or drilling residue into the inverter during
installation work.
• The inverter has passed the withstand voltage test before leaving the
factory, so it can not be tested again.
• For products stored for more than 2 years, the power supply shall be
boosted slowly through the voltage regulator when power on.
• Please tighten the terminal reliably.
• Do not connect the input power line to the output U/V/W terminal.
• Do not connect the phase shift capacitor to the output loop.
• Switch the motor or perform variable frequency/power frequency
switching when the inverter stops outputting.
• Do not short-circuit the inverter DC bus terminals.
