Operation input
When the contact is “Closed”, “Run” is to be input. Input SPEC: No-voltage “a” contact (When the applied voltage is 20 to 30V DC and the
contact is “Closed”, the welding current is approx. 10mA.) For input, use a contact for micro current. (12V DC, 1mA max.)
Abnormal input
When the contact is “Open” or “Closed”, “Error” is produced. Input specifications: No-voltage “a” contact (The welding current is approx. 10mA when
the applied voltage is 20 to 30V DC and the contact is “Closed”.) For input, use the contact for micro current. (12V DC, 1mA max.)

Wiring procedure
1 <F1/F2> wiring between this equipment and centralized control equipment is required.
2
The connection to the facility equipment and setting of various switches
are required. See the “Wiring with Facility equipment” paragraph.
3
Connect the power supply and earth.
See the “Power Supply & Earth wiring” paragraph.
3 For the wiring connection and clamping method, refer to the “Wiring lead-in” paragraph.
Power Supply & Earth Wiring
For power supply, 1~200-240V is used. The wiring to the power terminal block (L/N) is required. The electric wire used should
be 1.25 to 2.0mm2. After checking tht power supply specifications, make correct connections.
Connect the earth wiring to the “” terminal. Use a 2.0 mm2 wire.
