Connection delay after power cut
The electric cartridge has connection-delayed power stages after
a power cut according to the standard. This means that, after a
power cut that has lasted for more than three minutes, only power
stage one is connected, 6 kW. The remaining power is connected
approximately two hours after the power has returned.
For testing and inspection, the delay may be switched off
temporarily by short-circuiting the pins marked with arrows until
the LED goes out.

Load guard
A load guard VBB 12 TX is available as an accessory. It senses the
total load on the main fuses and reduces the power in the electric
cartridge in the event of overload. When the load on the main fuses
falls, the load guard reconnects the power disconnected in stages.
Further information is available in the instructions for the VBB 12TX.
