8.3.1.4 Terminal boxes
The terminal box is not included in the scope of supply.
Note
The terminal box box must have as a minimum, degree of protection IP54 according to
DIN IEC 60034-5.
• Install the corresponding seals between the spindle box and terminal box, as well as
at the terminal box cover.
8.3.1.5 Recommended grounding
Note
A protective conductor / bearing shield must be connected at the spindle box through a
good electrical connection.
The spindle housing / bearing shield must be electrically connected to the cooling jacket.
•
Use a protective conductor with the required minimum cross-section.
• Ground so there is a good conductive transition between the protective conductor and
spindle box protected against corrosion (e.g. bare contact surfaces with a coating of
Vaseline).
