If the LED strip is not lit before or after the ins-
tallation, please check ...
... whether the LED strip has contact with itself (i.e.
whether it is twisted) or with another metallic (conductive)
surface (short circuit)
... whether the power supply unit is plugged in (into a func-
tioning socket; in the case of socket strips with a switch:
check whether the switch is switched on) and check
whether the power supply unit is connected with
the Y-distribution cable (or LED connection cable)
... whether the plug of the LED connecting cables with the
Connector (PTF) is properly connected with the LED strip
Check whether ...
• the side with the black wire is applied to the contact
that is labelled with (-) “minus” on the strip. Corre-
spondingly red wire on plus (+24V).
• the Connector/PTF plug is turned to the right side.
The strip can be connected at the top and bottom, in
order to be able to switch the polarity (see item 1).
The Connector/PTF plug is provided with contacts on
the “thicker” side, i.e. if the plug has to be turned, you
might have to use the contacts on the bottom side of
the LED strip. However, then you’ll have to remove the
double-sided tape there first.
• the plug has slipped out during the glueing process
or while the connection was made. If you squeeze the
plug, a mandrel will push through the strip in order to
prevent this.
