(1) Creepage and clearance requirements should be applied accordingto the specific equipment isolation standards of an application. Care should be taken to maintainthe creepage and clearance distance of a board design to ensure that the mounting pads of theisolator on the printed-circuit board do not reduce this distance. Creepage and clearance on aprinted-circuit board become equal in certain cases. Techniques such as inserting grooves and/orribs on a printed circuit board are used to help increase these specifications.
(2) This coupler is suitable for safe electrical insulation (ISOW1044) and basic electrical insulation (ISOW1044B) only within the maximum operating ratings. Compliance with the safety ratings shall be ensured by means of suitable protective circuits.
(3) Testing is carried out in air or oil to determine the intrinsicsurge immunity of the isolation barrier.
(4) Apparent charge is electrical discharge caused by a partialdischarge (pd).
(5) All pins on each side of the barrier tied together creating atwo-terminal device
