How to replace fuses

The fuses are placed on a PCB inside the electric unit. See figures below for how to open the box.

Remember to disconnect the mains cable first! 

Unscrew all screws

To release the power supply, place a 

screw driver here and pull the latch 

downwards

To get more room to inspect and replace the fuses, it is best to move the power supply a little out of 

the way. This can be done without disconnection the wires. See figure below:
