B) Indoor Unit - BASETech 1437517 Bedienungsanleitung

b) Indoor Unit

The indoor unit has five terminal connections on the rear.
Plug the stripped wires into the corresponding terminal. For thin wires (or multi-strand conductors), you can push the
associated terminal latch with a flat-head screwdriver before you push in the wire (for multi-wired conductors, it is
recommended to use a wire-end sleeve or to solder the wire ends).
An incorrectly inserted wire can be taken out again just as easily. For this, hold the terminal lock pushed
and pull the wire out (do not apply any force!).
Connect the enclosed mains adapter correctly; always observe proper polarity (plus/+, minus/-).
As already described in the outdoor unit, you should keep the example colour markings when using connection cables
("Black", "Red", "White").
If you use cables in different colours, connect them according to the signal assignment ("GND", "VDD", "Audio").
