• When wiring, pay careful attention to the
polarity of the external power supply.
The load may operate incorrectly if the
polarity is reversed.
• Be sure to wire both terminals 21 and
22 (COM0 (+V)) of CN1.
• Be sure to wire both terminals 1 and 2
(COM1 (+V)) of CN1.
• Be sure to wire both terminals 23 and
24 (0 V) of CN1.
• Be sure to wire both terminals 3 and 4
(0 V) of CN1.
• When wiring, pay careful attention to the
polarity of the external power supply.
The load may operate incorrectly if the
polarity is reversed.
• Be sure to wire both terminals 21 and
22 (COM2 (+V)) of CN2.
• Be sure to wire both terminals 1 and 2
(COM3 (+V)) of CN2.
• Be sure to wire both terminals 23 and
24 (0 V) of CN2.
• Be sure to wire both terminals 3 and 4
(0 V) of CN2.
