Control Terminals
The following table defines the E3 Overload Relay control terminal
designations.
Features are available only with the E3 Plus Overload Relay (cat. nos. 193/592-EC2 and
193/592-EC3).
Available only on cat. nos. 193/592-EC5_ _.
An earth ground connection to this terminal will assist in obtaining compliance with
electromagnetic compatibility requirements.
The use of shielded cable is recommended for the positive PTC thermistor circuit to assist
in obtaining compliance with electromagnetic compatibility requirements.
Available only on cat. nos. 193/592-EC3_ _ and 193/592-EC4_ _.

Grounding
The following grounding recommendations are provided to ensure electromagnetic compatibility compliance during installation:
·
The earth ground terminal of the E3 Overload Relay shall be connected to a solid earth ground via a low-impedance connection.
·
Installations employing an external ground fault sensor shall ground the cable shield at the sensor with no connection made at the E3 Plus
Overload Relay.
·
The PTC thermistor cable shield shall be grounded at the E3 Plus Overload Relay with no connection made at the opposite end.
Wiring Diagrams
WARNING: When working on energized circuits, do not rely on the voltage and current information provided by the E3 and E3 Plus for personal safety. Always
use a portable voltage or current measurement device and measure the signal locally.
