HPR260XD Field Service Bulletin 808270 3
HPR260 and HPR260XD Transformer Wiring
Introduction
The HPR260 and HPR260XD transformer, part number 014295, has changed. The new transformer became
incorporated into these plasma systems starting with serial number 005469. The new transformer is compatible with
older HPR260and HPR260XD plasma systems but requires different primary wiring. When replacing the transformer in
HPR260 and HPR260XD plasma systems, use these instructions to wire the transformer properly.
Failure to follow the new wiring instructions in this Field Service Bulletin will result in damage not covered
by product warranty.
Purpose
This Field Service Bulletin provides a guide to making the primary wiring connections between the main contactor and the
new transformer of the HPR260 or HPR260XD plasma system. These connections require the use of a new wire group
if the plasma system meets the following criteria:
HPR260XD 400 – 415 V with serial numbers 005468 and earlier (transformer 014295 Rev F or earlier)
HPR260XD 200 – 208 V with serial numbers 005468 and earlier (transformer 014295 Rev F or earlier)
All HPR260 400 – 415 V and 200 – 208 V
All new HPR260XD plasma systems with serial numbers 005469 and higher do not require the new wire group. When
replacing the transformer in a new HPR260XD, use the existing wiring.
DANGER
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
All work requiring removal of the power supply cover must be performed by
a qualified technician.
See the Safety section of the system’s manual for more safety precautions.
