Safety Instructions

SDC / DHC 43

EN2H-0220 GE51 R1005

2.3 Do not separate the controller from the mains

If this happens, the back-up battery will be unnecessarily
stressed. In addition, the frost protection functions of the
controller will be out of order.

2.4 Electric

installation

Qualified personnel must carry out all electrical
connections.

2.5 Cable

dimensions

1.5 mm² for all 230 V cable (power supply, burner,
pumps, actuators).
0.5 mm² for sensors, selectors, bus and analogue in- and
outputs.

2.6 Maximum

cable

length

Sensors selectors and analogue inputs

A maximum cable length of 200 meters is recommended.
Longer distances are possible but increase the risk of
interferences.

Relay outputs

Unlimited cable length.

Bus connections

A maximum cable length of 100 meters is strongly
recommended.

2.7 Cable

installation

Cables for 230 V must be installed separate from low
voltage (sensor selector bus) cables.
