Refer to Figure 2-4, Item G, for typical 4-20mA connections.
2.1.2.7 Dielectric strength testing
It may be required to test a complete motor starter for dielectric strength (“flash” or “HIPOT”) with the EntelliPro ES
Installed. The EntelliPro ES is rated for 1.5 kV AC for 1 second isolation between relay contacts, EntelliPro ES
CT inputs and the PE terminal (66). Some precautions are required to prevent damage to the EntelliPro ES during
these tests.
To avoid damage to filter capacitors and transient suppressors by continuous high voltage, disconnect the PE
terminal during testing of power supply inputs. The CT inputs, inputs, and output relays do not require any special
precautions. Low voltage inputs (less than 30 volts), and RS485 communication ports are not to be tested for
dielectric strength under any circumstance.
