Note regarding E-Bus current
EL/ES terminals are placed on the DIN rail at a coupler on the terminal strand. A Bus Coupler can supply the
EL terminals added to it with the E-bus system voltage of 5 V; a coupler is thereby loadable up to 2 A as a
rule. Information on how much current each EL terminal requires from the E-bus supply is available online
and in the catalogue. If the added terminals require more current than the coupler can supply, then power
feed terminals (e.g. EL9410) must be inserted at appropriate places in the terminal strand.
The pre-calculated theoretical maximum E-Bus current is displayed in the TwinCAT System Manager as a
column value. A shortfall is marked by a negative total amount and an exclamation mark; a power feed
terminal is to be placed before such a position.

From TwinCAT 2.11 and above, a warning message "E-Bus Power of Terminal..." is output in the logger
window when such a configuration is activated:

Attention
Caution! Malfunction possible!
The same ground potential must be used for the E-Bus supply of all EtherCAT terminals in
a terminal block!
