When connected to a 12-24 Vdc source,
the auxiliary power supply module, type
OXEA1, supplies power to the external
Ekip-modules, HMI and main control unit.
It is supplied by external supply, for exam-
ple from generator battery or from iso-
lated transformer connected to the main
power circuit. Powering product only with
Auxiliary power supply module limits
some operation functions of the main
control unit, for example: Operation of
the main switch contacts is not possible.
Connections are push-in spring terminals,
no tool is required.
For external wiring, cable cross section;
