7 Safety Considerations

¡

To apply for safety standard approval using this power supply, the 
following conditions must be met.

¿

This unit must be used as a component of the end-use equipment.

¿

The equipment does neither contain any basic nor double / rein-

forced insulation between input and output.
If the input voltage is greater than 60VDC, this has to be provided 
by the end-use equipment according to the final build in condition.

¿

Safety approved fuse must be externally installed on input side.

Measuring Point

9.1 Delivery package information (SFS series 

SMD type)

¡

These are packed in a tray (Fig.9.1, 9.2).

¡

Capacity of the tray is 15 max.
In case of fractions, the units are stored in numerical order.
