4.1.2.2 Sample Gas Outlet Connection
The sample gas outlet connection is a ¼ inch compression fitting labeled Moisture
Sensor Outlet as shown in Figure 3. If a connection must be made to the exhaust,
it must provide minimal backpressure.
NOTE: If the Hydrogen Service Safety System is included, the sample outlet line
must be made of steel. See page 83 for additional information.

4.1.3 Electrical Connections
Open the door and locate the power switch in the center of the upper rail. Be sure
it is in the OFF position. Plug the line cord (supplied with 110VAC units only)
into the receptacle at the back of the analyzer. Verify the operating voltage is
proper according to the label on the rear and connect the line cord to the power
source. See
Figure 5 and Figure 6.
4.1.4 Hydrogen Service Safety System
This optional system is designed to safeguard the DF-745SGSG from explosion
hazards when operating on hydrogen sample gas under normal pressure and flow
conditions as detailed in the Operating Instruction Manual. The instrument
chassis is protected by maintaining a safe condition within the enclosure. If
