Operating the Saphir compact air
conditioning unit with the TG 1000 sinus
power inverter
The ElektrikSet (Electrical kit – part no. 40090-23100) and
the KlimaSet (Air conditioning kit – part no. 40090-25900)
are required in order to make the electrical connection of the
power inverter (part no. 40090-81000). A connecting diagram
and a description of the connection are provided with the
respective set.
Operating modes of the TG 1000 sinus
power inverter with the Saphir compact air
conditioning unit
The power inverter is controlled by the air conditioning
electronics after the air conditioning unit has been
switched on. The air conditioning unit checks the status of the
power inverter and the connected electrical supply at short in-
tervals (D+ of alternator, starter battery / auxiliary battery and
national network).
If the Saphir compact air conditioning unit is operated
with the TG 1000 sinus power inverter, the following
operating statuses are possible:
Operating mode 1
via auxiliary battery with 12 V
(vehicle engine off, alternator D+ is 0 V).
Switch on the Saphir compact air conditioning unit via the
remote handset.
– If the auxiliary battery voltage is higher than 12 V when
the unit is switched on, the Saphir compact air conditioning
unit is started.
Only FAN MODE with fan settings FAN LOW and
FAN HIGH can be used.
– If the auxiliary battery voltage is lower than 12 V, the red
LED on the IR receiver illuminates. The air conditioning unit
does not start up. Reset by switching the air conditioning
unit off.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the auxil-
iary battery has been recharged (above 12 V – no automatic
restart).
– If the voltage of the auxiliary battery drops to less than
10.8 V while the air conditioning unit is being operated,
the air conditioning unit with power inverter is switched
off completely to prevent further battery discharging. No
red LED therefore illuminates on the IR receiver as a fault
indicator.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the auxil-
iary battery has been recharged (above 12 V – no automatic
restart).
The air conditioning unit continues to run and the power
inverter switches itself off when the mains voltage is applied
(connection a – for national network input voltage, see
"Operating mode 3").

Operating mode 2
via alternator with 12 V
(vehicle engine running, alternator supplies D+ = 12 V)
The auxiliary battery and the starter battery are switched in
parallel via the isolating relay. The relay is actuated by D+ from
the alternator (or D+ substitute).
Switch on the Saphir compact air conditioning unit via the
remote handset.
– If the auxiliary battery voltage is higher than 12 V when
the unit is switched on, the Saphir compact air conditioning
unit is started.
The full functionality of the air conditioning unit is
available.
– If the air conditioning unit is operating and the engine is
switched off, the previous setting that was selected using
the remote handset is used when the vehicle is started
again. The switchover procedure is controlled by the
D+ signal.
Tip
To protect the batteries and limit the use of the alternator
charge current, switch electrical consumers off if possible
(e.g. switch refrigerator to gas operation).
–
When the engine is switched off the air conditioning unit
and the power inverter switch themselves off. The green
LED on the IR receiver flashes briefly.
– If the starter battery voltage drops to less than 11.7 V
or the auxiliary battery voltage drops to less than
10.8 V during operation, the air conditioning unit with
power inverter switches off completely to prevent further
battery discharging. No red LED therefore illuminates on
the IR receiver as a fault indicator.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the aux-
iliary / starter battery has been recharged (above 12 V – no
automatic restart).
The air conditioning unit and the power inverter switch them-
selves off when mains voltage is applied (connection a – for
national network input voltage, see "Operating mode 3"). The
red LED on the IR receiver illuminates. The air conditioning
unit must be switched on again via the remote hand set.
Operating mode 3
via national network with 230 V ~
The 230 V ~ national network is looped through from connec-
tor (a) to connector (c) via a relay in the power inverter. The
power inverter remains switched off. The air conditioning unit
can now be operated at any cooling setting.

The air conditioning unit with power inverter switches itself off
in the following cases:
– National network failure
– National network input voltage connector (a) is disconnected
