For safe connections, ensure that uninsulated tips of the wires do not

extend beyond the terminal block screws to which they are attached.

Voltage Selector Switch: Set the Voltage Selector switch to the source

voltage (115 or 230 V ac) that will be used to power the Analysis Unit
internal heater. Make sure the switch is set to the correct voltage BEFORE
making or energizing the power connections.

Power Connections: 115/230 V ac, 50/ 60 Hz power is required for

the heater that keeps the enclosure at a constant temperature. Connect per
standard power wiring codes. The connections are—

N Neutral, G Ground, H Hot.

Fuse Installation: Fuses are not installed at the factory. Be sure to

install the proper fuse (5

× 20 mm, 1.6 A) as part of installation. (See Fuse

Replacement in chapter 5, Maintenance.)

Solenoid and Sensor Signal Connections: The Remote Probe con-

nector on the Control Unit (Part I, paragraph 3.3) connects to the Analysis
Unit's Solenoid Valves and Sensor Signal terminals. See Figure 3-4. It
provides signals to control the solenoid valves which regulate the zero, span
and sample gas flow, and accepts the sensor and thermistor signals for
processing.
