with “IP Ring Bus” option:
In case of “IP Ring Bus” option be aware that external hazardous voltage can
be supplied from the IP cabinet (FU1, FU2, FU3 / Fig. 4.3.7-2) to the IM0278
(J19.10, J19.7, J19.4 / Fig. 4.3.7-1)

after UPS shut down.
To remove the hazardous voltages it is necessary to manually open the IP
cabinet fuses (FU1, FU2, FU3 / Fig. 4.3.7-2), checking the presence of any
voltage before working on the UPS.
Read carefully the documentation provided together with the external “IP
Ring Bus”
