3.2.4. Dielectric Strength (HIPOT) Testing
For dielectric strength (HIPOT) testing in the field, users must remove the metal jumper located
across terminals 2, 4, and 6 of the power supply terminal block. This metal jumper connects
transient suppression circuitry to chassis ground and must be removed in order to avoid damage
to transient suppression circuitry during HIPOT testing. The figure below shows the proper HIPOT
test connections and should be followed to avoid damage to the device.
