1 GETTING STARTED 1.1IMPORTANT PROCEDURES
Use this chapter for initial setup of your new F650 Feeder Protection Relay.
To help ensure years of trouble free operation, please read through the following chapter for information to help guide you
through the initial installation procedures of your new relay.
Before attempting to install or use the relay, it is imperative that all warnings and cautions in this manual are reviewed to
help prevent personal injury, equipment damage, and/or downtime.
The following safety and equipment symbols are used in this document.
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
Indicates practices not related to personal injury.
a) GENERAL CAUTIONS AND WARNINGS
The following general safety precautions and warnings apply.
Ensure that all connections to the product are correct so as to avoid accidental risk of shock
and/or fire, for example such as can arise from high voltage connected to low voltage
terminals.
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 on the
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 safety cautions 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, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to attempting work
on the device.
Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that current
transformer secondary circuits are shorted out before making or removing any connection to the current transformer (CT)
input terminals of the device.
For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such
equipment 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 switching apparatus,
all control circuits from the device to the primary equipment must be isolated while personnel are working on or around this
primary equipment to prevent any inadvertent command from this device.
Uses an external disconnect to isolate the mains voltage supply.
