4.1.2 System On/Off Circuit Breaker
The circuit breaker located on the bottom left side of the front panel disconnects the low voltage
supply of the MX Source from the three phase Line input. This will remove power from the mains
AC input contactor and thus remove input power from the MX Series power source. As such,
the circuit breaker acts as an indirect power on/off switch for the MX Series unit. Note however
than AC input power remains applied to the primary side of the input transformer.
When the input current rating of the MX Series AC power source is exceeded, the protective
fuses (F1 through F3) will blow. In this case, power to the low voltage supply may still remain
through the front panel circuit breaker. In this case, the on/off circuit breaker should be opened
(power off) first followed by a complete disconnect of all ac input power through an installed
main circuit breaker.
Note that in MX60, MX90 and MX135 systems, each unit has its own on/off circuit breaker and
set of line input fuses.
