Isolation Group
The device is considered a 2-terminal device; Pin 1 through Pin 4 are shorted together, and Pin 5 through Pin 8 are shorted together.
In accordance with UL1577, each device is proof tested by applying an insulation test voltage ≥ 3000 V rms for 1 second
(current leakage detection limit = 5 µA).
In accordance with DIN EN 60747-5-2, each device is proof tested by applying an insulation test voltage ≥ 1050 V peak for 1 second
(partial discharge detection limit = 5 pC).
