8.1
Insulation Resistance Test
An insulation resistance should be measured under the conditions specified below, in order to confirm
that the requirements of the judgment standard are met.
1) Measuring conditions
Measuring instrument : 500V DC MEGOHM Meter
Testing point : Between the power circuit block and the exposed metallic block
(D-SUB connector)
Measured value readout : A test voltage should be applied for one minute and the resistance
value should be read out thereafter.
2) Judgment standard:
The resistance of the insulation between the power terminal and the ground contact is more
than 10M ohms while withstanding a voltage of 500Vdc.
8.2
Dielectric Strength Test
To confirm the freedom from insulation breakdown, testing should be carried out under the conditions
specified below.
1) Measuring conditions
Measuring instrument: Dielectric strength tester (The specified voltage should be maintained in the
state that a current of 10mA is carried.)
Testing point: Between the electrical circuit block and the exposed metallic block (D-SUB
connector)
Note : The electrical circuit block should mean the power input block (primary side). Testing should
be carried out under the condition that both poles of the power plug are short-circuited. (Where
a 3-core cord is used, the two poles other than the
ground
terminal should be short-circuited.)
2) Judgment standard
There is no breakdown of the insulators or short circuits when applying an alternating potential of
1000Vac for a duration of 1(one) minute or 1500Vac for a duration of 2(two) second at 50Hz
between the metallic chassis and the input power supply active and neutral terminals connected
together.
