ELECTROCUTION HAZARD!
DEATH OR SERIOUS INJURY WILL OCCUR IF NOT AVOIDED!
An electrocution hazard exists because severe electrical shock hazards exist
when working around the high-voltage and/or 115/230 VAC components while
power is applied.
HOW TO PROCEED: Avoid hazard by turning off the unit with the ON/OFF
switch and remove the power connection or power cord from the unit to the
power source. Also, follow any required lock-out/tag-out procedures your
company policy requires.
To prevent electrical shock hazard DO NOT operate this equipment in rain or
wet conditions.
