Equipotential bonding
The boiler system must be connected to the equipotential bonding busbar as prescribed, via the connected pipeline
system as well as the pellet blow-in nozzle and suction nozzle.
The earthing strand of the conveyor hose must be connected to the fuel extractor and it
must be further connected to the earthing connection in the motor terminal box, so that it
is electrically conductive. This measure prevents static charges of the conveyor hose!
2.1.11.11 Sensor check
Please see the temperature/resistance characteristics below to function check the installed sensor:
