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 3 and 4 (COM0 (0 V)) of CN1.
• Be sure to wire both terminals 1 and 2 (+V) of CN1.
• Be sure to wire both terminals 3 and 4 (COM1) of CN2, and set the same polarity for both pins.
