Electrical Shock Hazard.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of
fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
