Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block.
• If you use a ferrule with a conductor length of 10 mm, part of the
conductor may be visible after the ferrule is inserted into the
terminal block, but the product insulation distance will still be
satisfied.
