The IFD is suitable for hard wiring only. Do not reverse
phase and neutral conductor. Different phases of a
three-phase current system must not be installed at
the IFD.
No voltage may be connected to the valve and ignition
outputs.
Do not use unused terminals as support terminals.
The signalling contacts for operating and fault signals
do not meet the requirements for safety extra low volt-
age (SELV/PELV).
The burner should be adequately grounded. Incor-
rect wiring and an insufficient ground connection can
cause damage to the equipment during single-elec-
trode operation.
In the case of single-electrode operation, only ignition
transformers of type TZI or TGI may be used. The use
of pulse-spark or high-frequency ignition devices is not
permitted.

Since EN 298 (1993) does not describe all functions of
the IFD, the operator is responsible for ensuring that all
parameters and functions are matched to the respec-
tive application.

During the safety time on start-up t
SA
, the burner must
be supplied with gas and ignited. For this reason, the
gas solenoid valve should be installed as close as pos-
sible to the burner itself.
