4.6 ELECTRICAL CONNECTIONS
4.6.1 Connectors
In the electrospindle there are two electrical connectors for power and signals respectively; the two
connectors are located in an electrical box also known as the “fixed mounting plate”. A “mobile
mounting plate” is also supplied with the electrospindle, with the mobile connectors to be wired by
the customer. Upon request, pre-wired “mobile mounting plates” are available, with cables of
different lengths.
The position of the electrical connectors is shown in section 2.
