standards. The using wire size refers to the preferred recommendation. Otherwise, an
accident may occur!
2. Never connect the braking resistor directly between the DC bus and the terminals.
Otherwise cause a fire!
3. Tighten the terminal with the specified torque screwdriver, otherwise there is the danger
of fire.
4. Do not connect the phase-shift capacitor LC / RC noise filter to the output circuit
5. Do not connect the electromagnetic switch or electromagnetic contactor to the output
circuit. Otherwise, the inverter over-current protection circuit is activated when severe, can
cause damage to the inverter.
6. Do not disassemble the connecting cable inside the inverter. Otherwise, the inverter may
be damaged.
Before Power-on:
Danger
1
、
Verify that input voltage is identical to the rated voltage of inverter, input terminals R,
S and T and output terminals U, V or W are correctly connected, there are no short circuit
phenomena for the wiring of inverter and its peripheral circuits, and all wires are in good
connection. Otherwise, this may result in inverter damage.
2、 Never perform voltage withstanding test on inverter, because it has been done at the
factory. Otherwise, this may result in accident.
Caution
1
、
The front cover of inverter must be closed before inverter is powered on. Otherwise, it
may result in an electric shock.
2
、
The wiring of all peripherals must be conducted in accordance with the guidance of
this manual. Otherwise, it may result in an electric hazard.
After Power-on:
Danger
1. Do not touch inverter or its peripheral circuits with wet hands to avoid the electric
shock.
2. If the indicator is off or the keypad does not display any information after power-on,
