Installation instructions for enhanced mechanical load capacity
| |
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 | Explanation |
|---|---|
Vibration | 10 frequency runs in 3 axes |
6 Hz < f < 60 Hz displacement 0.35 mm, constant amplitude | |
60.1 Hz < f < 500 Hz acceleration 5 g, constant amplitude | |
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.
