Grounding
The following grounding recommendations are provided to help ensure EMC
requirements during installation
.
• The earth ground terminal of the E300 Electronic Overload Relay shall be
connected to a solid earth ground via a low-impedance connection.
• Wire the green shield wire of the Cat. No. 193-ECM-ETR into the earth
ground terminal of the E300 control module.
• Installations employing an external ground fault sensor shall ground the
cable shield at the sensor with no connection made at the E300 Electronic
Overload Relay.
• The PTC thermistor cable shield shall be grounded at the E300 Electronic
Overload Relay with no connection made at the opposite end.
Short-Circuit Ratings
The E300 Electronic Overload Relay is suitable for use on circuits capable of
delivering not more than the RMS symmetrical amperes listed in the following
tables.
