Terminals for standard wiring
Fig. 18: Connecting a cable on a terminal point
Up to eight terminal points enable the connection of solid or finely stranded cables to the Bus Terminal. The
terminal points are implemented in spring force technology. Connect the cables as follows:
1. Open a terminal point by pushing a screwdriver straight against the stop into the square opening
above the terminal point. Do not turn the screwdriver or move it alternately (don't toggle).
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal point closes automatically when the pressure is released, holding the wire securely and
permanently.
Observe the requirements for connecting cables and cross sections according to IEC 60079-7 and IEC
60079-11. See the following tables for the suitable wire size width.

Maximum screwdriver width for ELX9560
Use a screwdriver with a maximum width of 2 mm to wire the ELX9560 power supply terminal. Wider
screwdrivers can damage the terminal points.
