Operating Voltage and Environmental Cautions
WARNING }
This instrument is designed for operation from a
power source with its neutral at or near earth
(ground) potential with a separate safety-earth con-
ductor. It is not intended for operation from two
phases of a multi-phase system, or across the legs of a
single-phase, three-wire system.
®
this instrument from one operating voltage to the other.
See Instruction Manual for futher information on DC
operation.
CAUTION
This instrument may be damaged if operated with the
Line Voltage Selector switch set to incorrect
positions for the line voltage applied.
115 V 90-136 V
230 V 180-272 V
The 485 is designed to be used with a three-wire AC
power system. If the three- to two-wire adapter is used to
connect this instrument to a two-wire AC power system, be
sure to connect the ground lead of the adapter to earth
(ground). Failure to complete the ground system may allow
the chassis of this instrument to be elevated above ground
potential and pose a shock hazard.
