Ⅱ. Safety Precautions
1. Before the Power-up
Caution
●
Check to be sure that the voltage of the main circuit AC power supply
matches the input voltage of the inverter.
●
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.
●
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
●
R.S.T 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.
●
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
●
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.
●
Mount the inverter on a metal or other noncombustible material to
avoid the risk of fire.
●
Install the inverter in a safe location, avoiding high temperature,
direct sunlight, humid air or water.
●
Keep the inverter from the reach of children or persons not
concerned.
●
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.
●
Install a heat sink or other cooling device when installing more than
