Protection Of Power Supply And Output Sections - Panasonic FP E Series User Manual

5.6.3 Protection of Power Supply and Output Sections

Power supply
An insulated power supply with an internal protective circuit should be used. The power supply for the
control unit operation is a non-insulated circuit, so if an incorrect voltage is directly applied, the internal
circuit may be damaged or destroyed. If using a power supply without a protective circuit, power should
be supplied through a protective element such as a fuse.
Protection of output
If current exceeding the rated control capacity is being supplied in the form of a motor lock current or a
coil shorting in an electromagnetic device, a protective element such as a fuse should be attached
externally.
