Danger!
Risk of death from live connections!
When working in the control cabinet of the
boiler there is a risk of death from electric
shock. Continuous voltage is present on the
mains connection terminals, even if the main
switch is turned off!
> Switch the main switch off before working
on the control cabinet of the boiler.
> Disconnect the boiler from the power
mains by disconnecting the mains plug or
by de-energising the boiler via an isolating
device with a contact opening of at least
3mm (e. g. fuses or power switches).
> Secure the power supply against being
switched on again.
> Open the control cabinet only when the
appliance is disconnected from the power
source.
