Proper Use

The charging current distributor ECL-75 and ECL-100 have been especially developed for
the use together with the roof air conditioning units of WAECO in drive- and stationary
operations.
This ensures an optimum power supply from the generator via the starter battery to the
supply battery. With insufficient charging through the generator, the integrated
undervoltage protection switches the air-conditioning off.
Possible combinations of roof air conditioning units and charging current distributors as
well as the necessary cable cross-sections of the supply line shown in the following table:

Technical description

The light machine generates a voltage of approx. 14 volts during driving which ensures a
recharging of the starter battery as well as the supply of the electrical power consuming
devices of the vehicle.
Additionally some mobile homes possess an electrical connection between starter- and
additional battery which is only then active when the vehicle engine is running. This line
is designed for currents up to 20 A. When operating the roof air-conditioning unit via the
inverter, the current consumption amounts to approx. 120 A from the 12 volts supply.
The possibly existing standard connection line between starter- and additional battery
would be overloaded since the generator must supply a large amount of the load current.
A remedy is provided by having an additional cable connection (at least 16 mm
75, at least 25 mm at ECL-100) between starter battery and additional battery which can

be switched on or off via a relay.
Likewise, the roof air-conditioning unit is switched off by means of the on-off line when
there is undervoltage.
The charging current distributors have two relay outputs which are used as follows:
Power relay to connect the starter and consumer battery
EasyCool:
Control relay to switch the inverter or the roof air conditioner on and off
CA-1000:
Control relay to switch the compressor on and off
