▪
As regards the output terminals, the equipment should be installed as close as possible to the LED module. In
the event that external NTC connection terminals are used to protect the module via the MTP functionality, the
maximum recommended length is 60 cm to avoid problems of interference and to achieve a more accurate
measurement. In any event, for correct operation, the maximum accepted distance between the driver and the LED
module is 2 metres.
▪
The connection cables must be appropriately insulated for the working voltage and comply with the level of
protection against electric shocks provided by the street lighting system.
▪
To avoid damaging the driver connectors, press the connector drive carefully when inserting or removing a cable.
▪
Ensure that the chassis and other internal metal parts, such as assembly plates, supports or dissipaters, are always
connected or electrically isolated. Make a reliable electrical connection between them by using serrated washers
and sufficiently tightened screws, ensuring that the connecting cables are as short as possible to minimise
inductances and thereby maximise their efficacy.
▪
In Class I luminaires, the protective earth conductor is strictly compulsory. Connect the protective earth to the
chassis and to the internal metal parts.
▪
In Class II luminaires, ELT recommends installing an equipotential connection or a star configuration functional
earth conductor between the chassis and every inaccessible conductive element of the lighting fixture, to avoid
issues with electromagnetic compatibility, to reduce residual brightness in the LED modules in standby mode and
to provide protection against shock waves.
▪
The installation of a switch at the driver output is not allowed as this could damage the LED modules as well as
the driver itself.
