CN5 Terminals Wiring
The layout of CN5 is shown in the figure below:

TA, TB and TC can be defined as multi-functional digital output signals. Please refer to Section 5.8.
If there are inductive loads, such as: electro-magnetic relay and contactor, surge snubber circuit, e.g. RC
circuit, varistor, fly-wheel diode (pay attention to the polarity when used in a DC circuit), should be
installed. Note that the leakage current should be less than the current in the contactor or relay. The
components in the snubber circuit should be installed near to the relay or contactor coil.
