For safe connections, ensure that no uninsulated wire extends outside of
the connectors they are attached to. Stripped wire ends must insert com-
pletely into terminal blocks. No uninsulated wiring should be able to come in
contact with fingers, tools or clothing during normal operation. Terminal
block can accept ware guage 20 to 10.
3.3.1 Primary Input Power
The universal power supply requires a 115 or 230 V ac, 50 or 60 Hz,
power source. The actual input voltage used must show in the window of the
VOLTAGE SELECTOR switch
before
the power source is connected. See
Figure 3-4 for detailed connections.
DANGER: Power is applied to the instrument's circuitry as
long as the instrument is connected to the power
source. The Standby function switches power on or
off to the displays and outputs only.
