2 ) Be sure to install a surge absorption circuit.

An appropriate circuit must be chosen according to the load

( for CR, choose its constant ) . This must be

carefully done especially for an inductive load.

3 ) For phase control, adjust such that the load current immediately after the input signal is applied will be
