1-2 F650 DIGITAL BAY CONTROLLER GEK-113000-AF1.1 IMPORTANT PROCEDURES CHAPTER 1: GETTING STARTED1.1.1.1 General cautions and warningsThe following general safety precautions and warnings apply.Follow the requirements of this manual, including adequate wiring size and type, terminal torque settings, voltage,current magnitudes applied, and adequate isolation/clearance in external wiring from high to low voltage circuits.Use the device only for its intended purpose and application.Ensure that all ground paths are uncompromised for safety purposes during device operation and service.Ensure that the control power applied to the device, the AC current, and voltage input match the ratings specified onthe relay nameplate. Do not apply current or voltage in excess of the specified limits.Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safetycautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltagetransformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior toattempting work on the device.Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure thatcurrent transformer secondary circuits are shorted out before making or removing any connection to the currenttransformer (CT) input terminals of the device.For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to suchequipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated,unless this is required by the test procedure and is specified by appropriate utility/plant procedure.When the device is used to control primary equipment, such as circuit breakers, isolators, and other switchingapparatus, all control circuits from the device to the primary equipment must be isolated while personnel are workingon or around this primary equipment to prevent any inadvertent command from this device.Uses an external disconnect to isolate the mains voltage supply.Figure 1-1: Front view of F650 unitWARNING Ensure that all connections to the product are correct so as to avoid accidental risk of shockand/or fire, for example such as can arise from high voltage connected to low voltage terminals.WARNING LED transmitters are classified as IEC 60825-1 Accessible Emission Limit (AEL) Class 1M. Class 1Mdevices are considered safe to the unaided eye. Do not view directly with optical instruments.NOTICE This product is rated to Class A emissions levels and is to be used in Utility, Substation Industrialenvironments. Not to be used near electronic devices rated for Class B levels.
