The
user
should
be
aware
of
these
safety
warnings
at
all
times
while
using
the
XT2640.
THE XT2640 MEASURES VOLTAGES AND CURRENTS WHICH MAY BE LETHAL; UNSAFE
OPERATION MAY RESULT IN SEVERE INJURY OR DEATH.
IF THE XT2640 IS USED IN A MANNER NOT SPECIFIED BY XITRON THE PROTECTION PROVIDED
BY THE EQUIPMENT MAY BE IMPAIRED AND SAFETY MAY BE COMPROMISED.
4.2
POWER
AND
GROUNDING
THE XT2640 IS INTENDED TO BE POWERED FROM A POWER CORD HAVING A PROTECTIVE
GROUND WIRE WHICH MUST BE INSERTED INTO A POWER OUTLET HAVING A PROTECTIVE
GROUND TERMINAL. IF THE XT2640 IS NOT POWERED FROM A SUITABLE POWER SOURCE, OR
IT IS LIKELY THAT THE POWER CORD MAY BE REMOVED FROM THE XT2640 WHEN MAINS
SIGNALS ARE APPLIED TO THE MEASUREMENT TERMINALS, THEN THE CHASSIS GROUND
TERMINAL LOCATED NEAR THE POWER ENTRY CONNECTOR ON THE REAR PANEL MUST BE
PROTECTIVE GROUNDED.
DO NOT REMOVE THE POWER CORD FROM THE XT2640 OR FROM THE SOURCE OF POWER
WHILE IT IS MEASURING HIGH VOLTAGES. THIS WILL REMOVE THE PROTECTIVE GROUND
FROM THE CHASSIS OF THE XT2640 WHICH MAY RESULT IN HAZARDOUS VOLTAGES BEING
ACCESSIBLE TO THE USER.
