Technician Notes
WARNING: Only authorized technicians trained by HP should attempt to repair this
equipment. All troubleshooting and repair procedures are detailed to allow only
subassembly/module-level repair. Because of the complexity of the individual boards
and subassemblies, no one should attempt to make repairs at the component level or
to make modifications to any printed wiring board. Improper repairs can create a safety
hazard.
WARNING: To prevent personal injury from electric shock and hazardous energy
levels, observe the following precautions:
•
The installation of options and routine maintenance and service of this product
must be performed by HP authorized service technicians who are knowledgeable
about the procedures, precautions, and hazards associated with AC power
products.
•
Remove all watches, rings, and any other metal or loose-fitting jewelry.
•
Avoid the use of conductive tools that could bridge live parts.
CAUTION:
To properly ventilate the system, you must provide at least 30.5 cm (12.0 inches)
of clearance at the front and back of the UPS.
NOTE:
Any indications of component replacement or printed wiring board modifications may void any
warranty.
