5.3.3 Output Wiring
Protection circuit of the inductive load
For inductive load, please install a protection circuit parallel with the load. When the DC
inductive load is switched on/off, the protection circuit has a great positive influence on the
service life, particularly for the relay output type. Therefore, make sure the diode is connected
at both ends of the load.
