10.2 Intended use

The inverter should only be operated in combination with the EC-1500-AC/
DC and EC-2000-AC/DC roof air conditioners.
Other installations are not allowed and can result in the inverter or the
connected device being destroyed.
The EC-1500-AC/DC and EC-2000-AC/DC roof air conditioners should be
operated with 230 V alternating current and a battery voltage of 12 V by
means of the ECW-012VS inverter from WAECO.
