sEnsOr InsTallaTIOn

Ground sensor - ETOG, figs 1+3:
For installation in outdoor surfaces where ice
and snow are a regular problem. The sensor
must be embedded horizontally with its top flush
with the surrounding surface.
The sensor cable must be installed in
accordance with current regulations.
NOTE: We strongly recommend the use of
cable pipes in order to protect the sensor cable.
Detailed installation instructions are supplied
with the sensor.
With ETOG-55, use the accompanying installation
plate.
With ETOG-56, use the ETOK-1 mounting kit.
