SAFETY NOTICE
SAFETY PRECAUTIONS
LEAKAGE CURRENT CHECK
The AC line cord of power supply connect to terminal.
And plug the AC line cord of power supply into a 120V
AC outlet. Use an AC voltmeter, having 5000
W
per volt
or more sensitivity.
Connect a 1500
W
10W resistor, paralleled by a 0.15
m
F
150V AC capacitor between a known good earth ground
(water pipe, conduit, etc.) and all exposed metal parts
of cabinet (screw heads etc.).
Measure the AC voltage across the 1500
W
resistor.
The test must be conducted with the AC switch on and
then repeated with the AC switch off. The AC voltage
indicated by the meter may not exceed 0.3V. A reading
exceeding 0.3V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with AC line reversed.
NEVER RETURN A CAMERA TO THE CUSTOMER
WITHOUT TAKING NECESSARY CORRECTIVE
ACTION.
READING SHOULD NOT EXCEED 0.3V
Test all exposed metal.
Voltmeter Hook-up for Leakage Current Check
The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
