AC Input and Internal Protection

A branch circuit disconnect must be provided in front of the amplifier.

Model

Three Phase Power

MPA-50-306

45 amps

80-260 Vac

AC power wiring must be consistent with any local codes, national electric codes, and be able
to withstand the voltage current ratings applied.

A

(ground) terminal is supplied and should be connected to earth ground.

Internal Protection

These amplifiers have internal AC Input fuses and a shunt fuse internal to the rear cover.  All
of these fuses are intended to avoid catastrophic failures.  These fuses are substantially larger
than needed.  In the event that any of these fuses become defective, the amplifier must be
repaired by a factory technician.
