• 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 23
and 24 (COM0) of CN1.
• Be sure to wire both terminals 3
and 4 (COM1) of CN1.
• Be sure to wire both terminals 21
and 22 (+V) of CN1.
• Be sure to wire both terminals 1
and 2 (+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 23
and 24 (COM2) of CN2.
• Be sure to wire both terminals 3
and 4 (COM3) of CN2.
• Be sure to wire both terminals 21
and 22 (+V) of CN2.
• Be sure to wire both terminals 1
and 2 (+V) of CN2.
