Sensor cable:
Attention
The following precautions must always be adhered to in order to not damage the sensors inside the
cable. Failing to comply with these precautions voids warranty.
Humidity
The sensor cable must always be protected from humidity, i.e. the cable ends
must
be sealed while sto-
ring or mounting the cable.
Bending
The minimum bending radius of the sensor cable is
25 cm
. This limit must be adhered to at all times in
order to not damage the sensors inside the cable!
Installation temperature
The sensor cable may
not
be installed below
+10 °C
of its own temperature (
+ 50 °F
)! The sensor cable
must have an own temperature between
+10 °C ... +40 °C
during the entire installation process (
+ 50 °F
… 104 °F
)! This limit must be adhered to at all times in order to not damage the sensors inside the cable!
