2.4 Input Power Precautions
This instrument operates from a single-phase, sine
wave, power source. It has a three-wire power cord
and requires a two-pole, three-terminal (live, neu-
tral, and ground) type input source. The voltage to
ground from the live pole of the power source must
be within the following rated operating voltage:
85V to 250V, 47 - 63 Hz, 250VA
The neutral pole must be at ground potential. Before
making connection to the power source, determine
that the instrument rating matches the voltage of
the power source. The power input plug must be
inserted only into a mating receptacle with a ground
contact. Do not bypass the grounding connection.
The ground terminal of the input supply cord (green
or yellow/green lead) must be connected to the
protective ground (earth) terminal of the line power
source. The black or brown cord lead is the live (hot)
lead.
The control circuits of the instrument are fuse pro-
tected. Fuse is located in the ON/OFF switch module
on side panel and is replaceable by the operator. To
avoid electric shock and fire hazard, use only the
fuse specified below switch module on side panel.
Before replacing the fuses, disconnect
the power input plug from the live power
source.
