WARNING Electrocution
Only components that operate with safety extra low
voltage (SELV) and that ensure secure separation from
the mains voltage supply may be connected to the low
voltage terminals of the appliance.
Connecting other components can make parts of the ap-
pliance and connected components live.
f Only use components which have been approved by
us.
