Make the ground connections first.
Only qualified personnel should install or replace this equipment.
Confirm that the DC power source is OFF during installation. The power source should be
a safety extra-low voltage (SELV) source.
Turn off power at the power source before you install or remove power cables or cords.
The unit should be connected to a DC branch circuit with a maximum 10A circuit breaker
or fuse that meets the requirements for branch circuit protection. A suitable disconnect
device must be provided in the DC branch, either a circuit breaker or switch that can be
employed to disconnect power to the system during servicing.
Before working on equipment that is connected to power, remove jewelry, such as rings,
necklaces, and watches. When metal objects are in contact with power and ground,
serious burns can occur or the objects can be welded to the terminals.
You must use cables that meet local electrical code requirements.
Do not install equipment that appears to be damaged.
The router and equipment rack must be properly grounded. Electrostatic discharge (ESD)
damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to
a nearby ground point that is connected to the site grounding point (typically, the
grounding stud on the 7705 SAR-8, or a properly grounded rack or work bench).
The 0V RTN terminal must always be connected to the building ground at the source.
If the disconnect device for the 7705 SAR-8 is not permanently incorporated, a readily
accessible disconnect device to shut off power during servicing must be incorporated in
your building's branch circuit.
