Installation and Wiring Chapter 2
➊ An earth ground connection to this terminal will assist in obtaining compliance with Electromagnetic
Compatibility requirements.
DeviceNet Terminals
The following table defines the DeviceNet connector terminal designations.
Grounding The following grounding recommendations are provided to ensure
Electromagnetic Compatibility compliance during installation:
• The earth ground terminal of the EC4 Current Monitoring 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 EC4 Current
Monitoring Relay
Short-Circuit Ratings The EC4 Current Monitoring Relay is suitable for use on circuits capable of
delivering not more than the RMS symmetrical amperes listed in the following
