3. Connection diagram
Connection diagram of XEC Supercap to XEV20D or IEV 22D driver to
control an electronic expansion valve.
XEC Supercap and XEV20D or IEV22D must be powered by two different
transformers; the failure of the observance of this rule may result in damage
to the XEC Supercap and / or the connected device.

control two electronic expansion valves.
XEC Supercap and XEV20D or IEV24D must be powered by two different
transformers; the failure of the observance of this rule may result in damage
to the XEC Supercap and / or the connected device.
If the XEV20D or IEV24D driver controls two expansion valves, two XEC
Supercap have to be used.
For both XEC Supercap:
respect the same power supply connection (terminal 1 of both XEC
Supercap has to be connected to the same pole of the transformer;
terminal 2 of both XEC Supercap has to be connected to the other
pole of the transformer)
terminal 3 (gnd) of both XEC Supercap has to be connected to the
“gnd” of the connected device; terminal 4 (+12V) of both XEC
Supercap has to be connected to the “In” of the connected device.
