5.1.2 Handling of the spring terminals
All terminal connections of the controller are implemented with grey mating connectors with spring terminals
(push-in spring connection). The connectors have the following characteristics:
S
Conductors with cross sections between 0.25 and 2.5 mm² can be used.
S
All mating connectors are coded and any reverse polarity is therefore ruled out.
S
For fast installation without tools, direct conductor connection of prefabricated cables (these with 10 mm wire
end sleeves) by simply inserting into the spring terminal is also possible.
S
The wires are disconnected using a screwdriver (max. 3.5 mm width) via the orange push button at the termi­
nal connection that has no direct contact to live parts:
Step 1: Press the orange push button vertically downwards using a screwdriver to detach the connection.
Step 2: Pull wire upwards.
The button must also be pressed during insertion to connect flexible wires of 0.25 to 2.5 mm²
without wire end sleeve.
S
For voltage testing, each terminal connection has openings for probe tips of multimeters (V) that are designed
with protection against direct contact:
Risk of damage! All mating connectors must always be guided vertically and attached / disconnec­
ted without twisting so that the pins on the main board are not bent and damaged.
