mandatory but recommended, as the wiring connector is
protected from direct contact.

of the panel. Fit the cables to exit towards the UPS and the load
on the lower side of the panel.
NOTE 3: Upstream of the distribution panel input line, install the
protection device prescribed in the UPS user manual
NOTE 4: For sizing of the minimum section of the cables, refer to the
UPS user manual.

the nominal current of the UPS connected.
