This section describes how to mount the M20.06 Controller and how to
connect it to AC power.

The M20.06 uses a switched-mode power supply which offers high
efficiency and low heat generation. This power supply accepts universal AC
Power input voltages in the range 100V AC to 240V AC (nominal), and
requires no setting adjustment for AC power voltages in this range. Minimum
AC input voltage is 90 Volts, and the maximum is 264 volts. Outside these
ranges the unit will not work satisfactorily, if at all. Voltages in excess of the
maximum will probably cause damage. Voltages below the minimum will
cause complete system shutdown. The flash memory in the M20.06 will
preserve all data in the event of a power failure.
A C p o w e r f u s i n g
The green-and-yellow wire of the mains cord must always be connected to
an installation safety earth or ground. The earth is essential for personal
safety as well as the correct operation of the system, and is internally
connected to all exposed metal surfaces. Any rack framework into which this
unit may be mounted is assumed to be connected to the same grounding
circuit.
The incoming mains power is fused within the M20.06 by the fuse holder
mounted on the rear panel. Always replace with an identical 20mm x 5mm
'T' fuse, rated at 1A for continued protection from equipment damage and
fire.
It is for safety reasons that this specification is strictly adhered to.
