CONNECTION OF DC-1000 OR DC-1500 to NA-3, LT-5 or LT-7
Connect the control cable ground lead to the frame terminal
marked near the power source terminal strip. The
power source must be properly grounded.
*If using an older control cable: Connect lead #75 to #75 on
terminal strip, connect lead #76 to #76 on terminal strip, connect
lead #77 to #77 on terminal strip.
N.A. Welding cables must be of proper capacity for the current
and duty cycle of immediate and future applications.
N.B. Extend lead 21 using #14 (2.5 mm 2 ) or larger insulated wire
physically suitable for the installation. An S16586-[ ] remote
voltage sensing work lead is available for this purpose.
Connect it directly to the work piece keeping it electrically
separate from the welding work lead circuit and connection.
For convenience, this extended #21 lead should be taped to
the welding work lead.
N.C. Tape up bolted connection.
N.D. Terminals 73 & 74 not present on earlier DC-1500.
N.E. Alternative 500 amp positive terminal connection provided
on DC-1000 models above code 9500 only.
Above diagram shows electrode connected positive. To change
polarity, turn power source off, reverse the electrode and work
leads at the power source and position the switch on power
source to proper polarity. Also reverse the leads on the back of
the ammeter and voltmeter in the automatic control box.
