Attention:
If relays, latching relays or inductive loads are con-
nected to an output, the EB8E4A has to be protected
against induction voltages!
At non-observance, defects may occur.
Ribbon cable
to ET 808A
Attention:
Maximum voltages at EB8E4A outputs:
With screwed enclosure (according to IEC/EN 60950-1 clause 2.1.1.1): 60 VDC / 30 VAC
Without enclosure, power supply option A
Without enclosure, power supply option B
The switching power must not exceed 60 W / 62.5 VA / 2 A!

For further information regarding the power supply,
Attention:
The module as well as all outputs may only be connected to a SELV LPS circuit!
When connecting voltage free contacts (switches, push buttons, relay outputs, etc.) to the digital inputs
of the EB8E4A, it is essential that in the switching position "ON" the switch resistance has to be less
than 1 kΩ.
