 SmallWarningYellow WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminal system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals!

Additional checks

The terminals have undergone the following additional tests:

Verification

Shocks
1000 shocks in each direction, in 3 axes
25 g, 6 ms

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.
