EWA 4NEB 780 6009-02c
Only safely isolated low voltage (DC 24 V) can be used as the power supply.
Safe isolation from the mains supply can be achieved in accordance with the
requirements in VDE 0100 Part 410 / HD 384-4-41 / IEC 364-4-41 (as func-
tional low voltage with safe isolation) or VDE 0805 / EN 60950 / IEC 950
(as safety extralow voltage with safe isolation SELV) or VDE 0106 Part 101.

Power Supply of the Terminal Block
The 1DIAC120/230V and 1DOAC120/230V1A electronic modules do not
require any auxiliary voltage (L+, M).
A supplementary terminal for connecting the protective conductor is required
when these electronic modules are used.
