grounding conductor is the same as that of the phase conductor (with the same cross
sectional area).
R, S and T are power input terminals, while U, V and W are output motor terminals. Please
connect the input power cables and motor cables correctly; otherwise the damage to the
inverter may occur.
1.4.2 Commissioning and running
Disconnect all power supplies applied to the inverter before the terminal wiring
and wait for at least the time designated on the inverter after disconnecting the
power supply.
High voltage is present inside the inverter during running. Do not carry out any
operation except for the keypad setting.
The inverter may start up by itself when starting at power-off is activated
(P01.21=1). Do not get close to the inverter and motor.
The inverter cannot be used as “Emergency-stop device”.
The inverter cannot be used as the motor brake under emergencies. A
mechanical brake device must be installed.
Note:
Do not switch on or off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check and adjust the capacitance and
perform pilot run before operating on the inverter
Cover the front board before running, otherwise electric shock may occur.
1.4.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform maintenance, inspection, and
component replacement of the inverter.
Disconnect all power supplies to the inverter before the terminal wiring. Wait for
at least the time designated on the inverter after disconnection.
Take measures to prevent screws, cables and other conductive matters from
falling into the inverter during maintenance and component replacement.
Note:
Please select proper torque to tighten the screws.
Keep the inverter, its components and parts away from combustible materials during
maintenance and component replacement.
Do not carry out any insulation and voltage endurance test on the inverter and do not
measure the control circuit of the inverter by megameter.
Proper measures must be taken against static electricity during maintenance and
component replacement.
1.4.3 What to do after disposal
The heavy metals in the inverter should be disposed as industrial waste.
