module
Safety precautions
To avoid possible bodily injury and power module and device
damage, follow these safety precautions:
•
When you install and remove a power module, always wear an
ESD wrist strap and make sure it makes good skin contact and
is well grounded.
•
Before you install the power module, make sure the voltage of
the power source is the same as the rated voltage of the power
module, and the output voltage of the power module is the same
as the required voltage.
•
Do not touch any naked cable or terminal of the power module.
•
Do not place the power module in a wet area, and prevent liquid
from flowing into the power module.
•
To avoid power module damage, do not open the power module.
When the internal circuits or components of the power module
fail, contact the maintainer for examining and repairing.
Tools
Prepare an ESD wrist strap and a flat-blade screwdriver yourself.
