Warnings and Notes
Danger:
• Installation and servicing must be done only by trained service personnel familiar with
potential electrical, mechanical, and laser radiation hazards.
• The 7705 SAR-A needs a disconnect device on each power feed, such as an external
5 A (minimum) and 10 A (maximum) circuit breaker or fuse that meets the requirements
for branch circuit protection.
• The 7705 SAR-A chassis and equipment rack must be properly grounded. Chassis
ground cables are not included. Lack of proper grounding (earthing) of the equipment
may result in a safety hazard and excessive electromagnetic emissions.
• The power source should be a safety extra-low voltage (SELV) source. Ensure that all
power is OFF from the DC circuit or AC power source before installing or servicing the
unit, before making the ground connection, and before installing or removing power
cables or cords. To switch the DC power OFF, locate the circuit breaker on the panel
board that services the DC circuit and switch the circuit breaker to the OFF position. For
extra safety, tape the handle of the circuit breaker in the OFF position. To switch the AC
power off, unplug the AC cord from the AC outlet.
• Be aware of all operating equipment in the area of the 7705 SAR-A installation. Make
safe any exposed power equipment, such as breaker panel bus bars or power
connectors on any nearby equipment. Either shut off the power, if possible, or install
safety guards or mats over exposed power points and cables. Tools used for power
connections should be insulated in an appropriate manner for the task.
• 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.
• The 7705 SAR-A uses a fiber-optic communications method and is a Class 1 laser
product. Only trained service personnel familiar with laser radiation hazards should
install or remove fiber-optic cables in this system.
