1.1.4 Wiring
A control panel must have cooling fans, air vents and room for ventilation when the drive is installed
inside.
The mounting surface in contact with the heat sink should be made of metal, which provides good
thermal conductivity and prevents flammability
Please check the dust-proof and moisture-proof conditions to avoid the external environment
affecting the inverter function.
Allow only qualified electrical engineers to install the drive. Failure to comply could cause electrical
shocks to personnel or damage to the drive.
Ensure the power supply is off when connecting. Failure to comply could cause electrical shocks.
Ensure the ground terminal PE is properly wired. Failure to comply could cause electrical shocks from
the drive cover. Therefore ground the drive and motor for personnel safety.
Do not touch the main circuit terminal. Keep the main circuit off drive cover to avoid electrical
shocks.
The terminal for braking resistor is B1 and B2. Do not connect it to any other terminals. Failure to
comply could cause a fire.
Do not connect three-phase power supply to terminals U, V and W. Failure to comply could damage
the drive.
An output reactor is recommended when the cable connecting between the drive and motor is over
100 meters. Failure to comply could result in drive damage with overcurrent caused by
over-distributed capacitance.
Never connect the output terminals to capacitors or unapproved LC/RC filters. Failure to comply
could damage the drive components.
Separate the drive main circuit cables and control circuit cables. Failure to comply could cause
interference to the control signals
Ensure the phase of power supply and rated voltage match the label on the drive. Failure to comply
could drive damage.
