Notes regarding clearance and creepage distances: The required clearance and creepage distances between HV and LV potential must be ensured. Layout of the PCB has to ensure min. clearance and creepage distances of conducting relay parts and relay terminal 1 and conducting relay parts and terminal 2 respectively. Refer to detail drawing.
