Note HV = high voltage pin

Remarks :

• Low voltage signals are on the bottom half. High voltage pins at the upper half.

• RING/POL are grouped together and should be routed together on the pcb.

• LN/DCI are grouped together. The highest possible DC current is flowing through these pins.

• Logic control signals are grouped together (RX, TX).

• AC0/AC1 switches AUX5, AUX10 and DP are as close as possible to LN.
