3. Connect sensor lines F I and F II or
FTS II according to circuit diagram 7 to termi-
nal 3 on the right-hand side.
• Insert supplied screwdriver A into the rectangular
recess of terminal strip B slightly push down, and
slightly tilt up:
• The terminal C underneath opens;
• Insert line D, tilt screwdriver down and remove.
• Check lines for secure fit.
Connecting the light cables
4. Run the light cables through opening H (connec-
tion range for 230 V / 400 V I) into the base of
the housing 1 and connect according to circuit
diagram 7 to terminal K (as described under
subitems of item 3.).
CAUTION - Damage to the unit
On installation an all-pin shut-off fixture needs to be
provided with a 3 mm contact gap (usually ensured
by the fuse).
Make sure all terminals/pins are assigned correctly.
Connecting supply and heat system lines
5. Run the supply and heat system lines through
openings E, F (connection range for 230 V / 400
V I) into the base of the housing 1 and connect
according to circuit diagram 7 to terminal J
with a max. tightening torque of 1.2 Nm.
NOTE - Further line inputs
Open further line inputs 7, G in the base of the
