4. Installation and Wiring

Explosion hazard! Do not mount the DGS Modbus in
an area that may contain flammable liquids, vapors,
or aerosols. Operation of any electrical equipment
in such an environment constitutes a safety hazard.
WARNING
The DGS contains sensitive electronic components
that can be easily damaged. Do not touch nor dis-
turb any of these components.
CAUTION
NOTE The mounting location of the monitor should allow
it to be easily accessible for visual monitoring and
servicing.
NOTE The monitor must be connected by a marked, suit-
ably located and easily reached switch or circuit-
breaker as means of disconnection
NOTE Connect monitor power and signaling terminals us-
ing wiring that complies with local electrical codes
or regulations for the intended application.
NOTE This instrument can be equipped with a semicon-
ductor sensor for the detection of refrigerant, com-
bustible or VOC gases. Semiconductor sensors are
not gas specific and respond to a variety of other
gases including propane exhaust, cleaners, and sol-
vents. Changes in temperature and humidity may
also affect the sensor's performance.

4.1 Electrical connection and diagram

NOTE: The wiring is the same for the semi-conductor and infrared
models. The controller wiring is the same for all controllers.
There is a 5-minute power-up delay to allow the sensor to stabi-
lise. Also see section 5.
Refer to Figure 1 for internal components and wiring.
