Terminal boxes
The position of the terminal box and cable entries can be
obtained from the tables below. The terminal boxes can be
rotated by 90° which allows the incoming supply cable to be fed
in from different sides.
Monitoring devices or anti-condensation heaters are connected
via auxiliary terminals in the terminal box. In frame size 132 and
above, the auxiliary terminals can be installed in an auxiliary
terminal box that is mounted on the side of the terminal box
corresponding to the type of protection of the motor. The design
of the terminal boxes can be seen in the schematic diagrams.
The number and size of the main and auxiliary terminals as well
as their characteristic data can be obtained from the tables
below.
