HPR260XD Transformer Wiring
HPR260 and HPR260XD 200/208 V model
Before you begin the wiring:
For ease of installation, make the wire connections starting from the bottom of the transformer with the
C connections and working your way up to the A connections.
Slide the heatshrink tubing onto the wire before connecting the wire.
Tighten all connections to 98 cm∙kg (85 in-lb).
Stack the wires as shown in Figure 4

1. Before fastening the new transformer to the plasma system base, be sure the transformer is pulled toward the open
side so that the transformer secondary wires have enough clearance from the center panel. This clearance is
especially important for the HPR260 and early model HPR260XD systems with serial numbers 005468 and earlier.
Maneuver the transformer to allow as much clearance as possible but still use existing bolt holes drilled into the base.
No metal from the secondary wires can touch the center panel.
The kit includes additional heatshrink tubing for the secondary wire connections.
2. Fasten the transformer to the base using the 3/4 inch wrench and tighten to 737 cm∙kg (640 in-lbs).
