Additional installation instructions
For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:
• The enhanced mechanical load capacity is valid for all permissible installation positions
• Use a mounting rail according to EN 60715 TH35-15
• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth
terminal or reinforced end clamp
• The maximum total extension of the terminal segment (without coupler) is:
64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)
• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of
the rail
• The mounting points of the mounting rail must be set at 5 cm intervals
• Use countersunk head screws to fasten the mounting rail
• The free length between the strain relief and the wire connection should be kept as short as possible. A
distance of approx. 10 cm should be maintained to the cable duct.
