Danger of electric shock
Danger to life! Risk of injury or a risk to life from electric shock!
The use of rigid lines (e.g. NYM) is not allowed because of the risk
of cable damages! There are only to use flexible cables, e.g
H05VV-F for high voltage power cables, and e.g. LIYY for sensor
cables.
6.6.2
Cable lengths
Bus/sensor lines do not have mains voltage, but safety extra-low voltage.
They must not be routed in parallel to the mains cables (interference
signals). Otherwise shielded cables must be installed.
Pipe length permitted:
Cu-cable up to 20 m: 0.8 mm
2
Cu-cable up to 80 m: 1 mm
2
Cu-cable up to 120m: 1.5 mm
2
Cable types : e.g. LIYY or LiYCY 2 x 0.8
6.6.3
Strain reliefs
All the cables should be fixed in the strain relief clamp of the control panel
and connected according to the connection diagram.
6.6.4
Circulating pumps
The permissible current load per pump output is I
N max
= 1A.
6.6.5
Appliance fuses
Appliance fuse in the control unit ISR:
Mains fuses: T 6.3A H 250V
6.6.6
Connecting sensors/components
Danger
Risk of electric shock! Danger to life through incorrect work!
The wiring diagram must be followed! Optional accessories must
be fitted and connected according to the instructions provided.
Connect to the mains. Check earthing.
Outdoor temperature sensor (included in delivery)
The outdoor temperature sensor is located in the accessory bag. It should
be connected according to the wiring diagram.
