BC-HM VI.72.M4.02 Danfoss 11/97 5
Electrical connections and
wiring diagram
Connection to 230 VAC -
(terminals 13-24)
The control must be connected using the
terminal strips with screw terminals.
Up to 3 x 1.5 mm² or corresponding
wires can be connected in each
terminal. The terminal strips are coded
to prevent terminal strips with mains
voltage being connected to sensor
terminals.
Terminal Load
Neutral (N) - 230 V~ 13
Phase (L) - 230 V~ 14
16 (close) 8(2)A 250V~
Reversible gear motor 230 V~, AMB, AMV etc.
17 (open) 8(2)A 250V~
Relay output R1 - 230 V~ (NC) 21 - 22 8(2)A 250V~
Relay output R2 - 230 V~ (NC) 23 - 24 8(2)A 250V~
Connections for sensors, etc. -
safety voltage (terminals 1 - 12)
Sensor mounting is described in the
instructions enclosed with the product.
Wire cross-section: min. 0.4 mm²
Total length of all sensor and BUS
wires: max. 150 metres.

Note!
Wire resistance can give measurement
error. A resistance of 4 ohm
corresponds to a temperature increase
of about 1 degree.
