Power supply for integral fan:
The power supply for the fan must be connected separately to the BC 110 (Id.-Nr. 254 740 01).
The connection to the +24 V machine control voltage must be according to VDE 0550.
Permissible voltage range +18 to +28 V; power consumption 5 W at +24 V DC.
The power supply for the fan is taken internally from the main supply voltage.
BE 212
The BE 212 visual display unit is powered through the LE 306 (connector X9).
Danger of electrical shock!
The BE 212 and BC 110 generate high voltages.
Unplug the power cord before opening the housing.
