3 Installation

3.3.1 Primary Input Power

The power cord receptacle and fuse block are located in the same as-
sembly. Insert the female plug end of the power cord into the power cord
receptacle.
DANGER: PowER Is APPlIED To THE INsTRUMENT's CIR-
CUITRy As loNG As THE INsTRUMENT Is CoN-
NECTED To THE PowER soURCE. THE RED I/o

The Control Unit is universal power 100-240V, 50-60 Hz. The Analy-
sis Unit requires 110 or 220 VAC and is selectable via switch located inside
the explosion-proof enclosure.

3.3.2 fuse Installation

The fuse block, at the right of the power cord receptacle, accepts US
or European size fuses. A jumper replaces the fuse in the neutral line when
the US size fuses are used. If the European size fuses are selected, both
sides at the line will be fused. Be sure to install the proper fuse as part of
installation. (See Fuse Replacement in chapter 5, maintenance.)

3.3.3 Analog outputs

There are four DC output signal connectors with spring terminals on
the panel. There are two wires per output with the polarity noted. See Fig-
ure 3-4. The outputs are:
