CAUTION
Alw
ays use the three-prong ac po
w
er cord supplied with this instrumen
t.
F
ailure to ensure adequate earth grounding by not using this cord maycause
instrument damage.
Before switc
hing on this pro duct, mak
esure that the line v

oltage of the p ow
er supply and the correct fuse is
installed. Assure the supply voltage is in the specied range.
This pro duct is designed for use in Installation Category IIand P
ollution
Degree 2per IEC 1010 and 664 respectively
.
Ven
tilation Requiremen
ts:
When installing the pro duct in acabinet, the
con
v
ection in
to and out of the pro duct m
ust not be restricted. The ambien


C for ev
ery 100 w
atts dissipated in the
cabinet. If the total po
w
er dissipated in the cabinet is greater than 00
w
atts, then forced con
vection must beused.
Before Applying P
