SAFETY INSTRUCTIONS FOR THE
ELECTRICAL INSTALLATION
• Electrical connections must be carried
out by a qualified technician, in
accordance with regulations applicable
to electrical systems.
• Make sure that the boiler is connected
to the earth.
• As far as the power input to the boiler is
concerned, the installation must comply
with standard EN 60364-1 that define the
applicable levels of insulation, and with
all provisions applicable to installation
conditions.
• For protection against electrical hazard,
it is always recommended to install a
differential cut-out device (Ground Fault
Isolator) on the power supply circuit,
upstream of the boiler.
• The control circuit is protected by a 3A
magnetic circuit breaker.
• The default electrical safeties integrated
in the boiler protect the internal parts of
the boiler.
• Any additional electrical safety device
must be installed outside the boiler.
• For protection against overheating, it is
advisable to place an external positive
safety power cut-out, controlled by the
boiler safety thermostat.
