Terminal Box
Series 8150/1, Series 8150/2
5.3.1 Fitting of attached components by R. STAHL
Give the following information to R. STAHL:
- Type
- Data sheet
- Quantity, manufacturers and approvals of the components that are to be attached.
R. STAHL
• will check whether the components, quantity and position correspond with the approval
• will mount the components
• will update the order documentation
• will carry out a routine test
• will, if necessary, fit a new type plate if the technical data has changed,
e.g. due to the components that are to be additionally attached.
5.3.2 Fitting of attached components by the customer
Select material
It is advisable to use the following materials when equipping the terminal box:
Cable entry
• for electric lines which are permanently installed: Plastic or metal cable entries for electric
lines which are permanently installed
• for electric lines which are not permanently installed: Plastic or metal cable entries with
strain relief.
Closing of unused entries
• Plastic or metal stopping plugs.
Drainage and pressure equalisation (prevention of the vacuum effect)
• Plastic or metal drain and breather valves.
Equip the device carefully and in accordance with the safety notes (see chapter 3).
Observe the specifications on the type plate of the device for the selection and operating
temperature of the components and seals.
Calculate the usable area for attached components; see sections 5.1.2 and 5.2.2.
Adjust the hole diameters of drilled holes to the dimensions of the built-in parts or
their seals!
The use of attached components with flat seal (gasket) is preferred.
5.4
Internal built-in components (conductors, terminals, fuses)
Ascertain the maximum number of conductors
Heat develops in every terminal box due to contact resistances at the terminals and
the cables installed in the enclosure. In order to ensure that the maximum temperatures
of a terminal box are not exceeded, care should be taken that the current load of
the circuits installed in the terminal box does not exceed certain values!
