A11.5 CLOSING UP: Secure all wires inside power supply cabinet and check
to be sure that connections are made correctly and that no loose strands of wire are
at any terminal point. If you have rotated the control out of the enclosure earlier,
carefully rotate it back and secure with the original four screws.
A12. LINE VOLTAGE SELECTION: If your line voltage was known to
Unitrol when this control was manufactured, it was factory connected to match that
voltage.
BEFORE TURNING POWER ON, verify that this was done correctly.
Check to see if the YELLOW wire on power supply terminal is connected to
a terminal that most closely matches your line voltage. See photos below for
your type of welding control.
Note: Controls shipped to Canada have two black wires connected to the
voltage input terminals. One will be marked F2. This goes to the F2 terminal.
IF THE ACTUAL LINE VOLTAGE IS MORE THAN 20% HIGHER THAN THE
TERMINAL MARKING, PERMANENT DAMAGE CAN OCCUR TO THE SYSTEM.
DAMAGE CAUSED BY OVERVOLTAGE IS NOT COVERED BY WARRANTY.
For 400V – 412V line voltages, set the yellow wire on the 380V terminal.
SUPPORT: If you have any doubts when installing this control, contact UNITROL
technical support 9:00 – 5:00 central time, M-F. We want to be sure that your
installation goes smoothly!
