For open-frame models (option Z), only the insulation input to outputs is tested.
The test voltage between outputs is not applied as routine test.
Isolation
The electric strength test is performed in the factory as a
routine test in accordance with EN 50116, EN 60950, and UL
60950 and should not be repeated in the field. Power-One will
not honor any warranty claims resulting from electric strength
field tests.
Options
i: Inhibit (Negative Shutdown Logic)
The outputs of the converter may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied to the inhibit
pin 8. If the inhibit function is not required the inhibit (pin 8)
06138a
should be connected to Vi– to enable the output (active low
logic, fail safe).
Voltage at pin 8:
Converter operating:
Converter disabled:
–10 V to 0.8 V
2.4 V to 20 V or left
open-circuit
Z: Open Frame
For applications, where the protection by a housing is not
necessary or in the case that the motherboard should be
lacquered after fitting the converter.
Note:
The converters shall not be exposed to cleaning processes,
as this will damage the glue of the ferrite cores.

If the inhibit pin is not used, connect it to Vi–.
Converters with a type designation ending by G are RoHS-
compliant for all six substances.
