Inverter easy cool
66 Installation and operating manual
10.2 Intended use
The inverter should only be operated in combination with the EC-2500-AC/DC
and EC-3000-AC/DC roof air conditioners.
Other installations are not allowed and can result in the inverter or the con-
nected device being destroyed.
The EC-2500-AC/DC and EC-3000-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.
10.3 Operating principle
The ECW-012VS inverter consists of 3 function units:
Generation of 230-V alternating current from 12-V battery supply.
Automatic switchover between external 230-V mains voltage and gener-
ated voltage of 230 V. The external supply has priority.
Charging of the 12-V supply battery with a maximum of 3 A, provided
external voltage is available.
