SAFETY
PRECAUTIONS
The following check should be performed
for the
continued protection of the customer and service
technician.
LEAKAGE
CURRENT
CHECK
Measure
leakage
current
to a known earthground
(water
pipe,
conduit,
etc.) by connecting
a leakage
current tester such as Simpson Model 229-2 or
equivalent
between
the earth
ground
and
all
exposed
metalparts
of the appliance
(input/output
terminals,
screwheads,
metal
overlays,
control
shaft,
etc.).Plug
theAC line
cord
of the appliance
directlyinto a 1
2OV
AC 6OHz
outlet and
turn the AC power switch on. Any
current measured
must not exceed O.SmA.
Reading
should
not be above
O.5mA
Test all
exposed metal
surfaces
2-wire cord
ANY MEASUREMENTS
NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO-
TENTIAL SHOCK HAZARD AND MUST BE COR-
RECTED
BEFORE
RETURNING
THE APPLIANCE
TO
THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many
electrical
andmechanical
parts
in
the appli-
ancehave
special
safety related
characteristics.
These
are often not evident from visualinspection
nor the
protection afforded by them necessarily
can be ob-
tained
byusingreplacement
components
rated
forvol-
tage, wattage, etc. Replacement
parts which have
these special
safety characteristics
are identified
in
this ServiceManual.
Electrical
components having such features are
identified
by marking
with a A onthe schematics
and
on the parts list in this ServiceManual.
The use
of a substitutereplacement
component which
dosenot have
the samesafety characteristics
asthe
PIONEER
recommended
replacement
one,shown in
theparts
list
inthis
ServiceManual,
maycreate
shock,
fire, or other hazards.
