Caution
● Do not touch the heat sink, braking resistor, or other heat elements.
These can become very hot.
● Be sure that the motor and machine is within the applicable speed
ranges before starting operation because the inverter is quite easy to
run from lower speed to higher speed.
● Do not check the signals on circuit boards while the inverter is
running to avoid danger.
● Be careful when changing the inverter settings. The inverter has been
adjusted and set before ex-work. Do not adjust it wantonly. Please
make proper adjustments according to the required functions.
● Do consider the vibration, noise and the speed limit of the motor
bearings and the mechanical devices when the inverter is running at
or above the frequency of 50Hz.
2. During the Power-up
Danger
● Do not plug the connectors of the inverter during the power up to
avoid any surge into the main control board due to plugging, which
might cause the damage of the inverter.
● Always have the protective cover in place before the power up to
avoid electrical shock injury.
3. During the Operation
Danger
● Never connect or disconnect the motor set while the inverter is in
running. Otherwise it will cause over-current trip and even burn up
the main circuit of the inverter.
● Never remove the front cover of the inverter while the inverter is
powered up to avoid any injury of electric shock.
● Do not come close to the machine when the fault restart function is
used to avoid anything unexpected. The motor may automatically
restart after its stop.
● The function of STOP Switch is only valid after setting, which is
different with the use of emergent stop switch. Please pay attention to
it when using it.
