or eye injury.

Fuse

To ensure that the system runs safely, when a fuse blows, replace it with a fuse of the same type

and specifications.

Electrostatic Discharge

The static electricity generated by the human body may damage the electrostatic sensitive

components on the circuit board, such as the large-scale integrated circuit (LSI).

CAUTION

Before installing or removing the power cable, turn off the power switch.

Before connecting the power cable, ensure that the power cable and label comply with the

requirements of the actual installation.

CAUTION

The human body generates a static electromagnetic field in the following situations:

movement of body parts, clothes friction, friction between shoes and the ground, and

holding plastic in hand. The static electromagnetic field will remain within the human body

for a long time.

Before contacting the device, plug boards, circuit boards, and application specific

integrated circuits (ASICs), wear a grounded ESD wrist strap. It can prevent the sensitive

components from being damaged by the static electricity in the human body.
