Fig. 5.8 Signals of auxiliary power supply module OXEA1
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 power circuit. Powering product
only with Auxiliary power supply module
limits some operation functions of the
main control unit, for example: Operation
of Sensor module isn't possible.
Connections are push-in spring terminals,
no tool is required.
For external wiring, cable cross section;
AWG 22-16 / 0.5-1.5 mm
