When use is made of a cable that utilizes the full overall height, the terminal's spring is
deflected to the maximum. Therefore, removal of this cable may become a problem because
it requires further deflection of the spring.

Connecting the push-in terminals
DANGER
Hazardous voltage.
Will cause death or serious injury.
Turn off and lock out all power supplying this device before working on this device.
NOTICE
Damage to property due to loss of overvoltage protection if wiring is wrong.
Observe the wiring's terminal assignment:
For optimum response in the event of short circuits and for protection against overvoltages,
the main circuit's infeed must be at terminals 1/L1 to 5/L3.
Push-in connections are a form of spring-loaded terminals allowing wiring without tools for
rigid conductors or conductors equipped with end sleeves.
For wiring finely stranded or stranded conductors without end sleeves on push-in
connections, a screwdriver is required.
Requirements
●
Screwdriver DIN 5264 of the size 0.5 x 3 mm (for finely-stranded conductors only)
●
For suitable connection cross-sections of the cables and notes on end sleeve finishing,
see Chapter Connection cross sections (Page 141).
