Proper line connection

Always connect only one wire per terminal point.
When using fine-wire conductors it is recommended to connect them with wire end sleeves in order to
establish a safe, conductive connection.
In addition, make sure that the pin assignment is correct to prevent damage to the ELX terminals and the
connected devices.
3.6.4

Shielding and potential separation

Shielding
Encoder, analog sensors and actors should always be connected with shielded, twisted paired
wires.
Observe installation requirements in areas of potentially explosive atmospheres!
During installation, observe the requirements for cables, shielding and earth potential equalization in areas
of potentially explosive atmospheres according to IEC 60079-11, IEC 60079-14 and IEC 60079-25.
Ensure potential separation of the 24 V Ex busbar!
In any case, make sure that the galvanic isolation made by the ELX9560 between the 24 V Ex busbar
(power contacts +24 V Ex and 0 V Ex) and other system potentials (if applicable also functional or protec-
tive earths) is not removed.
