. Safety Precautions
1. Before the Power-up
Caution
l
Check to be sure that the voltage of the main circuit AC power supply matches the input
voltage of the inverter.
l
The symbol, E , represents ground terminals. Be sure to make correct ground connection
of the earth terminals of the motor and the inverter for safety.
l
No contactor should be installed between the power supply and the inverter to be used for
starting or stopping of the inverter. Otherwise it will affect the service life of the inverter.
Danger
l
L1 L2 L3 terminals are power input terminals, never mixed with U.V.W terminals. Be sure that
the wiring of the main circuit is correct. Otherwise it will cause damages of the inverter when
the power is applied to it.
l
The terminal of E must be grounded separately and never connected to line zero.
Otherwise it will easily cause the protection or errors of the inverter.
Caution
l
Do not carry the front cover of the inverter directly when handling. It should be handled with
the base to prevent the fall-off of the front cover and avoid the dropping of the inverter, which
may possibly cause the injuries to people and the damages to the inverter.
l
Mount the inverter on a metal or other noncombustible material to avoid the risk of fire.
l
Install the inverter in a safe location, avoiding high temperature, direct sunlight, humid air or
water.
l
Keep the inverter from the reach of children or persons not concerned.
l
The inverter can only be used at the places accredited by our company. Any unauthorized
working environment may have the risks of fire, gas explosion, electric shock and other
incidents.
l
Install a heat sink or other cooling device when installing more than one inverter in the same
enclosure so that the temperature inside the enclosure be kept below 40
℃
to avoid overheat
or the risk of fire.
l
Be sure to turn off the power supply before dissembling or assembling the operation keypanel
and fixing the front cover to avoid bad contact causing faults or non-display of the operator.
l
Do not install the inverter in a space with explosive gas to avoid the risk of explosion.
l
If the inverter is used at or above 1000m above seal level, the cooling efficiency will be worse,
so please run it by de-rating.
l
Do not install any contactor and other components of capacitor or varistor on the output side
of the inverter. Otherwise it will cause malfunctions and damages of components of the
inverter.
l
Do not install any switch component like air circuit breaker or contactor at the output of the
inverter. If any of such components must be installed because of the requirements of process
and others, it must be ensured that the inverter has no output when the switch acts. In addition,
