the display with your fingers and pull it up.
z
Turn bezel over and pull off the 3-pin connector.
Connect the three wires for power and signal to the appropriate
terminal as indicated in the following wiring table and figure.
Fasten terminal screws with the correct torque according to the
table Tightening torque and wire size for field wiring terminal
see Section 8.6 on Page 24.
z
If operated as a stand-alone instrument, wire pin 1 to pin 3.
z
Plug connector back into socket.
z
The cable shielding should only be connected at the con-

1 Connector for DrägerSensor DD, LC, and DSIR
3.2.3 Remote sensor
The remote junction box (part number 4544098 for stainless
steel or 4544099 for aluminum) allows sensor installation at a
location away from the instrument electronics. This remote in-
stallation permits easy setup when the sensor must be located
in a difficult to reach or awkward position, see Polytron 5000
Junction Box Instructions for Use 4544286 for more details.
CAUTION
Ensure wiring for relays and connections for sensor
are made before applying power.
