Care must be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques such as inserting grooves, ribs, or both on a PCB are used to help increase these specifications. (2) This coupler is suitable for safe electrical insulation only within the safety ratings. Compliance with the safety ratings must be ensured by means of suitable protective circuits. (3) Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier. (4) Apparent charge is electrical discharge caused by a partial discharge (pd). (5) All pins on each side of the barrier are tied together, creating a two-pin device.
