5.3 Preparing the installation location
Please note:
The depth of the concrete foundation should be determined by the
local conditions: The foundation must reach into the frost-free zone in the ground.
The dimensions given for the foundation depth are typical values for conditions in
Central Europe.
We recommend that an empty conduit pipe (with a wire for pulling in) for the
connection and grounding cables is incorporated into the concrete foundation.
䡵
Attach the pedestal with bottom plate to a concrete foundation measuring
approx. 45 x 45 x 80 cm using the “Mounting kit for 2" pedestal“ (refer to
accessories); refer to Fig. 7 and appendix B.
Please note:
The pedestal must be as vertical as possible!
䡵
Pull the connection cable for the data collection device/power supply into the
empty conduit pipe.
䡵
OTT Pluvio
2
S with orifice rim heater: As applicable, pull additional connection
cable for the orifice rim heater power supply into the empty conduit pipe.
䡵
In case the ground for the OTT Pluvio
2
S is implemented centrally in the area
of the data collection device: Also pull the grounding cable into the empty con-
duit pipe (alternatively, the ground is established directly at the OTT Pluvio
2
S
using a concrete footing ground or ground rod).

For an OTT Pluvio

rim heater, an additional connection
cable may be used for supplying
power to the orifice rim heater.
The cables may alternatively be routed
outside of the pedestal. To protect the
cables (e.g. against animal bites), routing
the cables inside the pedestal is recom-
