1. Installation
Using the two pre-drilled holes (1), fasten the con-
nection socket to an even and firm surface. In order
to guarantee a high degree of protection, remove the
locking caps (2) from the base of the casing and place
them into the pre-drilled holes. If the connection so-
cket is to be used outdoors, drill open the condensa-
tion water hole located at the bottom corner of the
base of the socket. After having realized the electrical
connections (see below), close the cover with the two
screws (3).
2. Electrical connection
Perforate the chosen cable inlets with a sharp object
and insert the cables. Always insert the cables from
below in order to protect against penetrating humi-
dity. Use your fingers or a screwdriver to activate the
terminal clamps by pushing back the tongue lever.
Connect the sensor cable to clamps E1 and E2 and the
outgoing cable for the controller to clamps A1 and A2.
If polarity is an issue, keep in mind that E1 and A1 and
E2 and A2 are the respective current paths.
