-The MC BOX Electronic Panel does NOT come with protective switches;
it is therefore mandatory that the MC BOX be installed with an electrical panel
that is suitable to the individual MC BOX and has a differential power switch or,
at the very least, a fast-access device such as a socket/plug, to be used in the
event of anomalies;
-All the electronic components found within the MC BOX container have been
pre-wired and tested at the factory; as such, it is NEVER necessary to have the
MC BOX opened by the person who installed it or the plant operator, unless the
fuse protection on the I/O card needs to be replaced;
-The installer should carry out a plug/socket connection for a quick sectioning of
the electric system in case of failures.
WARNING
The MC BOX is equipped with 3 junction boxes. These can easily be accessed
by opening the door to where the screw terminals for the external cable connections
are located.
The connections that need to be made vary according to the model (AC or DC):
Before accessing the electrical parts, be sure that you have
disconnected all of the general switches that power the device.
