2.9 ELECTRICAL CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler must
be 230V - 50Hz single-phase through a 3 amp
fused main switch, with at least 3 mm spacing
between contacts.
Respect the L and N polarities and the earth
connection.
NOTE: SIME declines all responsibility for injury
or damage to persons, animals or property,
resulting from the failure to provide for proper
earthing of the appliance, or incorrect connec-
tion of external controls. Any fault or compo-
nent failure due to incorrect connection of
external controls is not covered in the warranty.
2.9.1 External controls (fig. 10)
Including connection of the RF clock kit Sime
part number 7102604 (BCG part 38493).
The heating demand on Format DGT boilers
can be controlled externally by either a volta-
ge free or 240 volt demand. In either case
the boiler MUST have a permanent power
supply.
