★
Dangerous high voltage exists during operation of the driver. Inappropriate operation may
result in serious personal injury. Dangerous high voltage still exists for a period of time after the
power is turned off.
★
Only trained and authorized qualified professionals can conduct driver maintenance.
★
Watch, ring and other metal objects of maintenance personnel must be removed before
operation. Clothing and tools that meet insulation requirements must be applied during
operation. Fail to observe the above requirements may lead to electric shock.
Caution

in the driver directly or through metal tools before confirm the following four items completely;
otherwise there is a risk of electric shock.
Shut off the drive power supply reliably, and wait at least 5 minutes;
●
Open cover plate of the driver after all LED indicators on the operating panel are off;
●
Charging indicator (CHARGE light) at the right lower of internal of the driver is off;
●
Measure voltage between main circuit terminal P ( + ), n ( - ) and confirm that the voltage is
lower than 36VDC
Prompt
Hidden fault of the driver may be caused by effect of temperature, humidity, pH, dust, vibration and other factors of the service
environment, as well as aging, wear of internal components of the driver and many other reasons. Therefore, routine inspection
must be conducted to the driver and driving system during storage and application, and make maintenance regularly.
