Power
Source
This product is intended to operate from a power module
connected to a power source that will not apply more than
250 volts rms between the supply conductors or between
either supply conductor and ground . A protective ground
connection by way of the grounding conductor in the power
cord is
essential
for safe
operation
.
Grounding
the
Product
This product is grounded through the grounding conductor
of
the
power
module
power cord .
To
avoid electrical
shock ,
plug
the power
cord into a
properly wired
receptacle
before
connecting to the product input or output terminals . A pro
tective ground connection by way of the grounding conduc
tor
in the
power
module
power
cord
is
essential for safe
operation .
Danger
Arising
From Loss
of
Ground
Upon
loss of
the
protective - ground
connection
, all accessi
ble conductive parts ( including knobs and controls that may
appear to
be
insulating )
can
render an
electric
shock .
Use the Proper Fuse
To avoid fire hazard , use only the fuse of correct type , volt
age
rating
and
current
rating as
specified in the
parts list
for
your
product
.
Refer fuse replacement to qualified service personnel .
Do Not Operate in Explosive Atmospheres
To avoid explosion , do not operate this product in an explo
sive
atmosphere
unless it has been
specifically
certified for
such
