Terminal Box
Series 8150/1, Series 8150/2
Dangerous (dark area of the table)
Terminal boxes which are designed according to this area require an additional
temperature-rise test.
Example calculation (general):
Ensure that operating temperatures – in particular low ones – of the terminal box and
the selected electric lines match.
5.4.2 Additional terminals
Fitting of additional terminals by R. STAHL
Forward the following information to R. STAHL:
- Type
- Manufacturer
- Data sheet
- Quantity
- Enclosure size
R. STAHL
• will check whether the terminal type, quantity, cross-section and current load correspond
with the approval
• will check whether the enclosure size, drilled holes and through holes are sufficient
• will install the terminals
• will, if necessary, create required drilled holes and fit required cable entries
• will update the order documentation
• will carry out a routine test
• will, if necessary, fit a new type plate if the technical data, such as current or conductor
cross-section, has changed.
Fitting of additional terminals by the customer
Modify the device carefully and only in accordance with the safety notes (see chapter 3).
Ascertain additional terminal points, terminal type, quantity, cross-section and current
load.
Check whether type plate data is changed as a result of subsequently equipping
(cross-section, voltage, current, etc.).
Check whether enough space and fastening options are available for equipping.
