5-4. Mounting Method
Insert the spacer (Maxφ8) of height more than 8mm to lift the unit. And use all mounting holes A for the unit installation. The vibration spec
is specified under this mounting condition.
Please use mounting hole B as needed. Vibratility-resistant improves

Condition to meet Isolation & Withstand Voltage standard.
■
Keep 4mm space from the surfaces and sides of PCB. Especially,
8mm space is necessary from the solder surface.
If the space is not enough, the specification of isolation and
withstand will not be satisfied.
Take the space in the power supply surroundings and the upper area of
components to keep enough for convection cooling.
