are lugs in the bottom of the enclosure where
the cables can be wound up.

tape to avoid short circuits.

COMMISSIONING
Power supply connection
The power supply can be connected to either
the indoor or outdoor unit. It is also possible
to feed in the power supply at a star point,
e.g. if all signal lines have been laid from the
fuse box to the outdoor and indoor units. The
power supply must then be connected in par-
allel with ground/GND and +15V. After all
components have been mounted and
connected, switch on the operating voltage.
Depending on the type of installation, plug
the power supply unit into a suitable socket
or switch on the circuit breaker to which the
DIN rail power supply unit is connected.
INSERTING MICRO SD CARDS
Open the indoor unit and carefully place it
with the monitor facing downwards on a soft
cloth to avoid scratching the glass. Slide the
microSD cards into the corresponding slots,
with the contact surfaces of the microSD
cards facing the circuit board. The slots are
equipped with a spring-loaded mechanism
that works like a biro. Push the card into the
slot until you hear a soft click and the card is
locked in place. To remove the cards, gently
press them into the card slot and then slowly
reduce the pressure. Be careful that the
microSD cards do not fly out of the slot due
to the spring pressure.
