HANDLING PRECAUTIONS
FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect
sensitive components from damage
due to electrostatic discharge (ESD)
during normal operation. When
performing installation procedures,
however, take proper static control
precautions to prevent damage to
equipment. If you are not sure of the
proper static control precautions,
contact your nearest sales or service
representative.
Optional Power Sources

choose one of the following power supply types.
