Warning!
Switch-off power supply before opening
the housing.
The unit should be located internally. It is not suitable for
installation in hazardous locations and should not be sited
near to any electromagnetic field.Please ensure sensor cables
and ac power supply are separated.
1. Choose a location, drill two holes of Ø 6 mm side by
side with a distance of 113 mm and fit in the enclosed
dowels.
2. Fix the controller by means of the enclosed screws (4 x
40 mm)(pos. 1).
3. The electrical connection must be effected now. Power
supply of the controller (210 ... 250 V ) must be effected
by external power switch.
Connection of the sensors at the clamps:
1 / 2 = sensor 1 (e. g. collector sensor)
3 / 4 = sensor 2 (e. g. store sensor)
Connection of the consumer to the clamps:
7 = normally open contact relay (RO)
8 = break contact relay (RC)
9 = neutral contact relay (N)
ground clamp (collective terminal strip)
ac power supply to the clamps:
10 = neutral conductor N
11 = conductor L

ground clamp
The guides of the required insertion channels must be broken
away at the bottom side of the cover.
The cables are to be fixed to the housing by enclosed strain
relief supports and screws (pos.2).
If necessary, activate anti-freeze function by jumper. If
protection against dripping water is required insert the
silicone sealing ring into the groove on the base plate taking
care not to stretch it.
Put on the cover and screw it (pos. 3). If necessary, adjust
temperature difference ∆T.
Put on housing cover and screw it (pos. 4).
