6.1 Dielectric Test Procedure After Transformer
Replacement
This document specifies the procedure steps to be taken to perform a Dielectric
Voltage Withstand test for the 750 product line after the power transformers T1 and
T3 have been removed and replaced.
CAUTION:
Risk of Electric Shock – The procedure you are about to follow places a
high voltage from conductive to grounded parts of the Unit Under Test
(UUT). This voltage could shock either yourself or bystanders. You
should never touch the UUT when the test is underway and notify
bystanders about the test you will be conducting.

6.3 UUT Preparation
If a single module (RT) system is being tested, proceed to paragraph 6.3.1; if a
multi-module system is being tested, proceed to paragraph 6.3.2.
