Terminal Connections
• When wiring, pay careful attention to the polarity of the external power supply. The load may operate if
polarity is reversed.
• Be sure to wire both terminals A19 and A9 (COM0 (0 V)) of CN1.
• Be sure to wire both terminals B19 and B9 (COM1 (0 V)) of CN1.
• Be sure to wire both terminals A20 and A10 (+V) of CN1.
• Be sure to wire both terminals B20 and B10 (+V) of CN1.
• Be sure to wire both terminals A9 and A18 (COM2) of CN2, and set the same polarity for both pins.
• Be sure to wire both terminals B9 and B18 (COM3) of CN2, and set the same polarity for both pins.
