Maintenance And Cleaning - HomeMatic RS485 Installationsanleitung

If an overvoltage causes excessively high restricted
currents to occur, the fuse integrated in the device
trips and the "Power" indicator light goes out.
If this happens, switch the mains connection to the
power supply unit off and replace the fuse with one
of the same tripping current and the same type:
- Glass tube fuse 5 x 20 mm, 6.3 A/250 V TH –
The fuse holder is removed by pushing it down and
turning it anticlockwise and inserted by pushing it in
and turning it clockwise.
Only use a fuse with a high breaking capacity
(1500 A, designation H), otherwise lightning
protection cannot be ensured.
