Utilizing surface-mount technologyand low-power electronics, the CL-7 control is CE(Commonwealth Europe) compliant. The nameplate locatedon the control box defines the power circuit.The CL-7 control provides the first of its kind single- ormulti-phase voltage regulation utilizing a single controlplatform. During every step of develop, focus was placed onproducing a control to meet the growing demand for smartgrid ready features and for flexibility to meet the needsof the future. While great effort was put into enhancingits features, the CL-7 control remains true to its roots bymaintaining the ease of use of its predecessor CL controls.The control features the same look and feel of the earliercontrols and whenever possible, the same function codeswere utilized. The CL-7 control allows keypad programming,Metering-PLUS™ status inquiries, USB memory deviceuploading and downloading, and multiple communicationports with user-selectable protocols of DNP3 (serial andIP), IEC 60870-5-101 and -104, Cooper 2179, Modbus RTU,Modbus TCP. LED indicators provide instant information onalarm, communications, and regulation condition status. Afour-line display provides detailed information and furthersimplifies programming. In addition, the CL-7 control ishighly configurable and ready for use in applications whereeither digital or analog SCADA is required.1INSTALLATION, OPERATION, AND MAINTENANCE INSTRUCTIONS MN225003EN April 2018CL-7 Voltage Regulator Control
