Safety Practices and Precautions, Continued
Correct Operating
Voltage Before switching on the power, check that the operating voltage listed on
the equipment nameplate agrees with the available line voltage.
DANGER Arising
from Loss of Ground Any interruption of the grounding conductor inside or outside the
equipment or loose connection of the grounding conductor can result in a
dangerous unit. Intentional interruption of the grounding conductor is not
permitted.
Safe Equipment If it is determined that the equipment cannot be operated safely, it should
be taken out of operation and secured against unintentional usage.
Use the Proper Fuse To avoid fire hazard, use only a fuse of the correct type, voltage rating
and current rating as specified in the parts list for your product. Use of
repaired fuses or short-circuiting of the fuse switch is not permitted.
Safety Guidelines DO NOT open the equipment to perform any adjustments,
measurements, maintenance, parts replacement or repairs until all power
supplies have been disconnected.
Only a properly trained technician should work on any equipment with
power still applied.
When opening covers or removing parts, exercise extreme care since
"live parts or connections can be exposed".
Capacitors in the equipment can retain their charge even after the unit
has been disconnected from all power supplies.
