• To improve noise immunity, it is recom-
mended to attach a ferrite core to the
power cord.
Attaching the Power Switch cover
For the AC type to conform to ANSI/ISA
standards, the Power Switch cover needs to
be attached to the main unit.
To prevent the USB cable
from coming off
Attaching the USB Cable Clamp
(1) Place the PS-A unit face-down on a flat
surface as shown below. Your PS-A unit
has four USB connectors.
• When using two or more USB ports, be
sure to first connect one USB cable to the
lower USB connector, and then connect the
second USB cable to the upper USB
connector.
• When using only one of the USB ports, be
sure to use the lower USB connector. This
allows you to securely clamp the USB
cable in the cable clamp.
(2) As shown, insert the USB Cable Clamp’s
band through the Bridge. Pass the USB
cables through the Cable Clamp’s band
and securely tighten the clamp band
around the cables.
• Be sure the clamp is securely holding the
USB cable’s plug and collar.
• Be sure the clamp is positioned as shown
below, with the clamp pointing upwards -
not to the side. This is to keep the clamp
from interfering with nearby connectors
and their cables.
Removing the USB Cable Clamp
(1) To remove the clamp from the USB
cables, push down on the clamp strap’s
clip to release it while pulling up on the
clamp.
