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.
The DSU/CSU is typically powered by the ac power module. Use the
following procedures only if you want to use an optional SELV (Safety Extra
Low Voltage) dc power source.
Using the optional dc power cable, the DSU/CSU is capable of operating on
either a +24 Vdc power source, – 48 Vdc single source battery, or – 48 Vdc
redundant source batteries (for power backup). To use dc power, choose one of
the following power supply types.
To install the DSU/CSU using a +24 Vdc SELV power supply, refer to
