Chapter 3 Installation Section

Power Supply

The Model SSM is supplied with the Model PS3-1.5 power supply that
offers a variety of mounting options. The power supply may be placed
on any flat surface, permanently affixed to a flat surface, or mounted on
a single rack rail with the optional rack mount adapter.

One of the primary reasons that the power supply of the SSM is external
is to insure that the power transformer enclosed within the power supply
chassis maintains a safe distance from the active electronics of the SSM
and the Expander. For that matter, any power supply (especially the
small wall mount supplies), power amplifiers, or any strong power field
device should be kept at a reasonable distance from the SSM and
Expander. It is also important to keep the above mentioned devices clear
of all interface cables, audio cables and harnesses.

The external power supply for the SSM does not provide an AC power
switch. It is recommended the power supply be plugged into an AC
strip that uses a power switch.

The power supply should not be installed directly above or below the
mixers. It is recommended that it be installed in the rear of the
equipment rack, providing that it remains at a reasonable distance from
the mixers and cables, and has adequate ventilation.

The power supply normally generates a small amount of heat during
operation. It is important that adequate ventilation is provided when
planning the mounting location.

The power supply may be wired to operate with 120 VAC, 220 VAC,
230 VAC, or 240 VAC 50/60hz. Before applying AC power, you
should verify that the voltage setting on your power supply is configured
to match the AC requirements of your country. This procedure should
be performed and checked by a qualified technician.

Unless otherwise specified on the panel of the supply, the power supply
is wired for 120 VAC 50/60Hz operation and uses a North American
style AC plug.

To gain access to the inside of the power supply, it will be necessary to
remove the top cover. This is accomplished by removing the 4 screws on
the bottom of the power supply chassis. Make certain that the power
supply is unplugged from the AC before proceeding.
