Before switching on the power, check that the operating voltage listed on
the equipment agrees with the available line voltage.
Any interruption of the grounding conductor inside or outside the equip-
ment or loose connection of the grounding conductor can result in a dan-
gerous unit. Intentional interruption of the grounding conductor is not
permitted.
If it is determined that the equipment cannot be operated safely, it should
be taken out of operation and secured against unintentional usage.
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.
DO NOT open the equipment to perform any adjustments, measure-
ments, maintenance, parts replacement or repairs until all power sup-
plies 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.
