CONNECTION
The power supply connection of the ignition transformer
occurs by means of Stelvio 3-way connectors; the high
voltage part is connected by means of 2,8X0,5 fast-on
connectors.The following figures showthe connectors and
the wiring diagram.

Some control boxes, like forexample types MT…, are
prearranged to work with one electrode only for both
ignition and flame detection.In such cases, the wiring

INSTALLATION
− Connect and disconnect the ignition transformer only
after switching offpower supply.
− Respect the applicable national and European
standards (e.g. EN 60355-1 /EN 50165 /EN 61558-1-
2-3) regarding electrical safety.
− Make sure the earthof the transformer and the earth of
the electrical system are well connected The device can
be mounted in any position.
− Avoid placing high voltage cables close to other cables.
− Make sure the protection degree is suitable tothe
system.
− Reduce the ignition cable length toaminimum (this
reduces stray capacitance and the possibility that the
ignition cable acts like an antenna transferring
interference to the nearby cables).
− Make ignition cables followaseparate path close to
ground planes (this reduces the influence of
interference on the remaining electrical wires).
− Arrange asingle earth centre, thus preventing earth
conductors from creating ring paths.
