Wiring/electrical connections
NOTE
Cable cross-section too small.
Excessive voltage drop and/or bonding not guaranteed!
►
A cable cross-section of at least 0.75 mm² must be used for the fan bus.
NOTE
Incorrect wire ferrules connecting the stranded wires in the controller connector.
Short circuit in fan bus!
►
Use wire ferrules with collar to connect stranded wires.
TIP
Exclusively lay the cable while it is not live.
Disconnect the power supply to the controller before sealing/connecting the cable.
Seal/connect the cable only while it is not live.
TIP
Use stranded wires to connect the fan bus to the ventilation unit. The fan bus terminal can take
wires with a cross-section of up to 1.5 mm². This makes it possible to arrange the ventilation
systems in a bus structure. We recommend using a LiYY3x0.75 round cable.
