4.3 - Installation Instructions
The Nimbus IoT is rated IP20, and should be mounted in a protective enclosure to protect the
unit from weather conditions and dust. If using the Nimbus IoT with WiFi, the unit must be lo-
cated within range of a WiFi network. Maximum distance is 1476ft (450m) with Line Of Sight.
A - Plastic Enclosure
(Fig 1)
Prepare the
Plastic Enclosure
(not supplied)
as illustrated by mounting a
DIN 35 rail
, cable
glands, and any other required components.
If you are using the WiFi model, the antenna
may be mounted directly on the Nimbus
IoT (inside the
Plastic Enclosure
). A cellu-
lar modem may also be installed inside the
enclosure.
B - Metal Enclosure
(Fig 2)
Prepare the
Metal Enclosure
(not supplied)
as illustrated by mounting a
DIN 35 rail
, cable
glands, and any other required components.
This enclosure type should be earthed.
If you are using the WiFi model or a cellu-
lar modem, a
Metal Enclosure
will impede
your signal strength. In these cases, the an-
tenna should be installed on the outside of
the enclosure using a compatible
Antenna
Extension Cable
. N.B. exterior mounting is
only suitable for indoor/covered outdoor
environments where antenna is protected
from rain or wet conditions.
