3) Wiring of relay output terminals(TA, TB, TC)
If an inductive load, such as electromagnetic relay, contactor and electromagnetic brake, is driven, a surge
voltage absorbing circuit, voltage-dependent resistor or continuous current diode (used in DC electromagnetic
circuit. Be careful of the polarity during installation) should be installed. The components of the absorbing
circuit should be installed near the sides of the winding of the relay or contactor, as shown below.
