Greystone Energy Systems GDT Series Installation Instructions Manual

BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the gas sensor. Failure to follow
these instructions may result in product damage. Do not use this device in an explosive or hazardous
environment, with combustible or flammable gases, as a safety or emergency stop device or in any other
application where failure of the product could result in personal injury. Follow electronic discharge
precautions during installation and do not exceed the device ratings.
MOUNTING
For wall mounting, select a suitable mounting
area away from opening windows or doors and
avoid areas subject to high vibrations or excessive
moisture. The recommended mounting height is
1.2 - 1.8 m (4' - 6') above the floor. The enclosure
has a hinged cover with a latch. Open the cover
by pulling slightly on the latch on the right side
of the enclosure as shown in Figure 1. Mount the
device directly to the flat surface using the four
integrated mounting holes that are provided on
each corner of the enclosure using screws (not
provided). Ensure the sensor pods are pointing
downwards as shown in Figure 1.
The enclosure offers two entry points for wiring
one on top and one on bottom, see Figure 2 for
locations. The enclosure includes one rubber
grommet installed in the bottom wiring hole.
Depending on the installation wiring can be routed
through top or bottom hole and the grommet can
be placed in the unused hole. The hole provided
is for conduit or cable gland mounting. The hole
size is 21.38mm (0.86") diameter.
Make wiring connections as per the "Wiring"
illustrations as shown in Figure 6. Once the wiring
and device setup are complete, close and latch
the cover. The enclosure includes a hole to allow
the use of anti-tamper device.
REMOTE NO MOUNTING
2
The recommended mounting height for the
remote NO2 sensor is 0.6 m (2') below the ceiling
and must be mounted within 3m (10') of the
main enclosure as shown in Figure 3. Secure the
enclosure to the selected section of wall above the main enclosure with (2) #10 x 25 mm (1") self-tapping
screws (not provided) and tighten screws until the enclosure is tight against the wall as shown in Figure 4.
Ensure there is no movement of the enclosure.
