• When wiring, pay careful attention to
the polarity of the external power
supply. The load may operate incor-
rectly if the polarity is reversed.
• Be sure to wire both terminals A9
and A19 (COM0) of CN1.
• Be sure to wire both terminals B9
and B19 (COM1) of CN1.
• Be sure to wire both terminals A10
and A20 (+V) of CN1.
• Be sure to wire both terminals B10
and B20 (+V) of CN1.
• When wiring, pay careful attention to
the polarity of the external power
supply. The load may operate incor-
rectly if the polarity is reversed.
• Be sure to wire both terminals A9
and A19 (COM2) of CN2.
• Be sure to wire both terminals B9
and B19 (COM3) of CN2.
• Be sure to wire both terminals A10
and A20 (+V) of CN2.
• Be sure to wire both terminals B10
and B20 (+V) of CN2.
