WARNING:
Connect the electronic drive only to Safety Extra Low Voltage (SELV) circuits. The circuits
provided for use with external communications and control equipment are designed to provide
isolation from neighboring hazardous circuits within the drive. The communications and control
circuits within the ecocircXL drive are floating from ground and are classified as SELV. They must
be connected only to other SELV circuits in a manner which maintains all the circuits within SELV
limits and prevents ground loops. Physical and electrical separation of the communications and
control circuits from non-SELV electrical circuits must be maintained both within the inverter and
external to the inverters.
