Installing and removing a power module
Safety precautions
To avoid possible bodily injury and power module and device damage,
follow these safety precautions:
•
When installing and removing a power module, always wear an
ESD-preventive wrist strap and make sure it makes good skin
contact.
•
Before installing the power module, to avoid power module and
device damage, make sure that the voltage of the power supply
system is the same as the rated voltage of the power module, and
the output voltage of the power module is the same as the voltage
required by the device.
•
To avoid bodily injury, do not touch any cables or terminals 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.
