MX Series 96
3.15 Fuse Box Accessory
An Output Fuse Box (P/N 7003-426-1) is provided with MX systems consisting
of more than 2 cabinets. This fuse box provides protection against excessive
current circulating between amplifiers in different chassis in case of a system
malfunction.
Each fuse can sustain up to 125 Arms of AC current, which is the maximum
available current per MX amplifier.
Each fuse box has 9 sets of 3 fuses for phase A, phase B and phase C. Each fuse
terminal is lined up with a strain relief on each side of the box. The outputs from
the MX45 cabinets connect to the “MX 45 SOURCE” side of fuse box. The
outputs of the fuse box (marked “JUNCTION BOX” are normally routed to the
7003-416-1 Junction box (marked “MX SYSTEM OUTPUT”) where the outputs of
the various cabinets are combined for each phase. The load can then be
connected to the “LOAD” side of the junction box.
NOTE: The Fuse box enclosure must be connected to Earth ground
using the provided ground stud.
