NSTALLATION OF WATERPROOF HOUSING
The housing for waterproof models can be fixed to a wall or, for outdoor installations, to a
40 mm
diameter mast by means of
HD2003.77/40 clamping
(for housing H=120 mm x L=80 mm)
.
Fig. 9.2.1: installation of waterproof housing
F
or outdoor installations
, use the optional protection shield against solar radiations (
for hous-
ing H=120 mm x L=80 mm
).
Data loggers supplied with clamping already mounted on the back of the housing are equipped
with protection devices against over-voltages connected to the clamping. For a correct opera-
tion of the protecting devices, the yellow/green wire with fast-on connector connected to the
clamping should be connected to ground.
The outdoor installation of the combined temperature and relative humidity probe requires
HD9007A-1 or HD9007A-2 protection against solar radiations.

dure. If the device belongs to a wireless network and the base unit is reachable, after connection
the buzzer emits a second beep and the green RF LED blinks during data transmission. If the de-
vice doesn’t belong to a wireless network and the base unit is not reachable, the second beep of
the buzzer is not emitted and the red RF LED will blink.
