3.2 WIRING

All LEN series loudspeakers are passive systems designed
for use with external amplifiers. They have identical ca-
bling connectors and can be supplied with a choice of two
options:
2 × 4 plastic terminal blocks are supplied as standard.
These are suitable for wires with a cross section of up
to 4 mm².
The loudspeakers can also be supplied with 2 × 4 ce-
ramic terminal blocks. These are suitable for wires with
a cross section of up to 2.5 mm².
For models with a built-in 100 V / 70 V transformer, two
directly connected terminals for each pin are available for
in-/outputting Signal -(Com), Signal +100 %, Signal +50 %
and Signal +25 %. This allows the signal to be daisy-chained
to the next loudspeaker.
SEE FIGURE ABOVE.
All cables used must be of an appropriate cross section. We
recommend using ferrules for stranded wires.
A sealing plate is attached to each loudspeaker, along with
two M16 cable glands. Once cabling has been completed,
this can be used to cover the connector panel and provide
tension relief for the cable.
Please be aware of the fact that the specified degree of
protection (in accordance with IEC 60529) is only obtained
by mounting the sealing plate correctly. The cable glands
are suitable for use with cables of between 6 and 10 mm
in diameter.
If only one cable is being used, the other cable gland
should be replaced by the dummy plug that has been sup-
plied with the loudspeaker.
