5.6 Installing the base plate on the pedestal
䡵
Place the base plate onto the pedestal such that the connection and grounding
cables come out of the slit in the base plate flange (see Fig. 14).
䡵
Lead connection and grounding cables through the opening in the base plate
upwards.
䡵
Rotate the base plate so that terminal block of the orifice ring
heater is facing southwards*!
In extreme climatic conditions, this will
prevent incorrect precipitation value output. These may occur during heavy
rapid temperature variations together with lateral solar irradiation.
* on the southern hemisphere: northwards
䡵
Insert the six hexagon bolts into the base plate flange with open-ended wrench,
size 13 mm (supplied).
Please note:
insert all hexagon bolts approximately to the same depth! Do
not yet fully tighten the hexagon bolts!
