2.3.2 Power Supply Cautions
When connecting the PS-A unit’s AC connector, please be aware of the following:
• If voltage fluctuations are expected to vary
beyond the specified range, connect a con-
stant voltage transformer.
• Use a low-noise power supply both between
the lines and between the PS-A and its
ground. If there is still excess noise, connect
an insulating transformer (noise-prevention
type).

For information about the
specified voltage, refer to
7.1 General Specifications
(page7-2)
• Be sure any constant or insu-
lating transformer used has a
capacity of 200VA or more.
