Preface
WARNING
ohm. Neutral line is absolutely not allowed to replace earth wire. Otherwise, it may result in
malfunction of the device due to the interference;
Wiring should be firm and steady, or misoperation may occur;
Voltage values and positive & negative polarity of any connection plug should be in accordance
with specifications set forth in the manual, or it may result in breakdowns such as short circuit
and permanent damage to the device;
To guard against electric shock or CNC device damage, fingers should keep dry before
plugging or touching switch;
The connecting wire should not be damaged and squeezed, or the leakage or short circuit may
occur;
It is prohibited to plug or open the chassis of CNC device when power on.
4) Precautions Related to Running & Debugging
Parameters setting should be checked before running, since wrong setting may lead to
accidental movements;
Modification to parameters should be within the allowable range, or such breakdowns as
unsteady running and machine damage will occur.
5) Precautions in Use
Before power-on, please make sure that the switch is on blackout to avoid occasional start-up;
Please check the electromagnetic compatibility during electrical design in order to avoid or
reduce electromagnetic interference to the CNC device. A low pass filter should be employed
to reduce electromagnetic interference if there are other electrical devices nearby;
It is not allowed to frequently power on and power off. It is recommended to power up the
machine again at least one (1) minute later after power failure or blackout.
