The auxiliary power supply module, type
OXEA1, supplies non-insulated power to
the external Ekip-modules, HMI and main
control unit. It is supplied by external sup-
ply, for example from generator battery or
from isolated transformer connected to
the main circuit. Powering product only
with Auxiliary power supply module limits
some operation functions of the main
control unit, for example: Operation of

Connections are push-in spring terminals,
no tool is required.
For external wiring, cable cross section;
AWG 22-16 / 0,5-1,5 mm
