12-10. Withstand Voltage Test
This converter is designed to withstand
2000V between primary (DC320V) and chassis(
) ,
2000V between secondary(DC240V) and chassis(
),
400V between signals and chassis(
),
2200V between primary (DC320V) and secondary(DC240V),
3000V between primary (DC320V) and signals,
3000V between secondary(DC240V) and signals
each for 1minute.
The applied voltage must be gradually increased from zero to testing value and then gradually decreased to zero.
When timer is used the unit may be damaged by high rate of change of voltage at turn on/off. Ramp the voltage even
if using a timer. CV and –V as follows.
・
Secondary(DC240V) and chassis(
) is more than 100M
Ω
at 1000VDC.
・
Signals and chassis(
) is more than 100M
Ω
at 500VDC.
*All pins of RS-485 and CN connectors must be shorted.
・
primary (DC320V) and chassis(
)
:
2000VAC, 1min(50mA)
・
secondary(DC240V) and chassis(
)
:
2000VAC, 1min(50mA)
