• For AC operation, the unit requires two common 4 Amp/250 volts 20mm x 5mm Slow-
blow fuses that are contained within a fuse holder that is press-fit into the body of the
IEC power inlet module (on the rear panel of the unit).
• For DC operation, the unit requires two different fuses that are contained within the
individual screw-in receptacles below the terminal block (on the rear panel of the unit).
These DC fuse requirements are as follows:
o Modem Operation – 3 Amp/250 volts 20mm x 5mm Slow-blow fuse.
o BUC Operation – 6.3 Amp/250 volts 20mm x 5mm Slow-blow fuse.
