b) Digital input terminals (RUN, X1, RST, PLC and CM)
1) Normally a circuit across the digital input terminal and the CM terminal is connected or disconnected. On the
other hand, if the open collector output of a programmable logic controller driven by an external power supply is
used to turn on or off, a routing circuit may cause malfunction.
If this happens, use a PLC terminal to connect as shown in Figure 3.3-12.
2) When using a contact input, use a contact free from contact faults having high contact reliability.

c) Transistor output terminals (Y1, Y2, Y3 and CME)
1) Take care of the polarity of the external power supply.
2) When connecting a control relay, connect a surge absorbing diode at both ends of the exciting coil.
d) Contact output terminals (Y5A, Y5C, 30A, 30B and 30C)
Contact capacity is 250 VAC 0.3A cos
θ
= 0.3. If these specification values are exceeded, connect a relay having a
larger contact capacity. If two or more contacts are necessary, connect a relay having multiple contacts to increase
contacts.

e) Charging circuit control signals
(73A and 73C)
These are control output signals for the charging circuit. Perform wiring, referring to the basic connection
diagrams.
