Configuring Grounds
To avoid unwanted interferences to the supply voltages of the ES4408.1 Load
Chassis, the load side is isolated from the supply voltages via a DC/DC
converter.
The actual load reference potential is the output ground of the DC/DC
converter which can then be referred to battery ground -UBatt via jumper
“X29”.

LEDs
There is an LED on the front panel of the ES4434.1 Configurable Load Board
for every load – it is addressed by comparators and always lights up when the
voltage at the ECU pin is greater than 6 V.
