Before plugging or unplugging any cables, shut down the device and disconnect the power
supply. While plugging or unplugging any cable, ensure that your hands are dry.
Do not step on, pull, or overly bend any cable. Otherwise, the cable may become damaged,
leading to the malfunctioning of the device.
Do not use old or damaged cables.
In lightning weather, disconnect the device from the power supply and unplug all the cables
connected to the device.
Keep the power plug clean and dry, to prevent electric shock or other dangers.
If the device is not used for a long time, disconnect the power supply and unplug the power
plug.
If smoke, sound, or smell is emitted from the device, stop using the device immediately,
disconnect the power supply, unplug the power plug and other cables, and remove the
batteries. Then, contact the appointed maintenance center for repair.
Ensure that no object (such as metal shavings) enters the device through the heat dissipation
vent.
Before connecting any other cable, connect the ground cable of the device. Do not
disconnect the ground cable until you have disconnected all the other cables.
Ensure that the three-phase power socket is grounded properly. The neutral line and the

Use only the recommended battery. Pay attention to the polarity of the batteries while
installing them.
If a battery does not fit in the device, do not apply force. Otherwise, the battery may leak
or explode.

Zn battery cannot be used together. You are recommended to use batteries of the same
model manufactured by the same manufacturer.
Do not use a new battery with an old battery. When you replace batteries, replace all of
them at the same time.
If you are not going to use the device for a long time, remove all the batteries.
If any battery leaks, emits smoke, or emits abnormal smell, stop using it immediately.
