Clamping the cables
Cables should be connected to WAGO connector, leaving approximately
3 cm of tail. They should be stripped with 6-7 mm of metal showing and
these should be connected as in the diagram above. A small screwdriver
with blade size approx 3.5 mm can be used. WAGO part no 210-719
is
ideal for this use.
Outer shields should be collected and grounded in a ground stud on the
edge of the cabinet. The outer insulation should be cable tied to the plastic
handle of the connector, and securely anchored nearby. The plugs when re-
fitted, must be installed such that their clips are fully in the up position.
