Secure adequate
space
around the power switch.
Do not
place the PLZ-U
in a location
that
would result in poor accessibility to the
switch. And, do
not place
objects near the switch that would result
in poor accessi-
bility.
Do not place
objects
on
the PLZ-U.
Placing objects on top of
the PLZ-U can cause failures (especially heavy
objects).
Do
not
place the
PLZ-U
on an inclined surface or location
sub-
ject to vibrations.
The
PLZ-U may fall
or tip over causing damages and
injuries.
Do not use
the PLZ-U in a
location where strong
magnetic or
electric fields
are nearby or a
location where
large amount of
distortion and
noise is present on the
input power supply
waveform.
The
PLZ-U may
malfunction.
Do not use
the PLZ-U
near highly sensitive
measuring instru-
ments or
transceivers.
The noise
