• Expose the braid.
• Remove the braid and insulation little by
little.
• With thin cables, the braid can be folded
back over the insulation sheath.
• Insert the cable into the gland until the
braid reaches the contact point.
• Tighten the cable gland.
Step 2
• Guide the cable through the lock nut.
• Guide the cable into the terminal insert.
• Fold the braid over the insert.
• The braid must overlap the O-ring by
about 2 mm
