For connection, press the actuation pushbutton
of the spring-type terminal using a screwdriver and
insert the wire to its stop in the appropriate port.
Release the actuation pushbutton and
pull the cable slightly to ensure that it
is safely clamped.
Important!
Before closing the terminal cover, make
sure the strain relief device is tightened safely.
Check once more that all cables are in good
condition and connected correctly.
The strain relief device can only ensure solid
clamping if the cables are not stripped to a length
of over 35 mm.
Insulation of the individual wires must be
removed over a length of 9 - 10 mm to ensure
safe electric contact in the spring-type terminal.
Stranded wires must be provided with cable end sleeves!
