No. Wiring procedure
<F1/F2> wiring between this equipment and centralized control equipment is required.
The connection to the facility equipment and setting of various switches are required.
See the "Wiring with Facility equipment" paragraph.
Connect the power supply and earth.
See the "Power Supply & Earth wiring" paragraph.
For the wiring connection and clamping method, refer to the "Wiring lead-in" paragraph.
Wiring with Facility Equipment
<Caution> The length of wiring between this equipment and facility equipment is 100m max.
Operation output
It is possible to select continuous 1 output (4 points) or instantaneous 2 output (ON/OFF pair - 2 points).
• Wiring at Continuous Output (Up to 4 facility equipments can be connected.)

(Terminal size: M3.5)
Output SPEC: No-voltage "a" contact
Voltage SPEC Maximum current
200-240V 1.5A (Resistive Load)
DC5~24V 2A (Resistive Load)
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.)

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 2.0mm
correct connections.
