Safety Precautions
Before using this equipment, please read this chapter carefully.
This chapter describes the safety precautions recommended when using the GR
equipment. Before installing and using the equipment, this chapter must be thoroughly read
and understood.
Explanation of symbols used
Signal words such as DANGER, WARNING, and CAUTION, will be followed by
important safety information that must be carefully reviewed.
Indicates an imminently hazardous situation which will result in
death or serious injury if you do not follow the instructions.
Indicates a potentially hazardous situation which could result in
death or serious injury if you do not follow the instructions.
CAUTION Indicates a potentially hazardous situation which if not avoided,
may result in minor injury or moderate injury or property damage.
•Current transformer circuit
Never allow the current transformer (CT) secondary circuit connected to this equipment to
be opened while the primary system is live. Opening the CT circuit will produce a
dangerously high voltage.
•Exposed terminals
Do not touch the terminals of this equipment while the power is on, as the high voltage
generated is dangerous.
•Fiber optic

CAUTION
•Earth
The earthing terminal of the equipment must be securely earthed.
CAUTION
•Operating environment
The equipment must only be used within the range of ambient temperature, humidity and
dust detailed in the specification and in an environment free of abnormal vibration.
•Ratings
Before applying AC voltage and current or the DC power supply to the equipment, check
that they conform to the equipment ratings.
•Printed circuit board
Do not attach and remove printed circuit boards when the DC power to the equipment is
on, as this may cause the equipment to malfunction.
•External circuit
When connecting the output contacts of the equipment to an external circuit, carefully
check the supply voltage used in order to prevent the connected circuit from overheating.
•Connection cable
Carefully handle the connection cable without applying excessive force.
•Modification
Do not modify this equipment, as this may cause the equipment to malfunction.
•Short-wire(link)
Do not remove the short-link wire(s) connected to the frame earth (FG) at the terminal block
on the rear of the relay.
•Electric wire on DC/DC power-supply (between #17 - FG)
Make sure the wire is connected.
(Exception: This wire needs to be detached for performing the dielectric voltage test.)

Equipment installation and operation
•Equipment installation
Never remove cables at frame ground terminals (FGs) while the AC/DC power supplies.
•Equipment operation
The user shall have responsibilities to use and install the equipment where the
specifications are designated by the manufacture. Never operate the equipment on the
condition where the manufacture cannot intend. Otherwise, the safety function furnished
into the equipment may not be operated properly.

†The implementation of particular features is dependent upon a hardware structure and a
software model and several IEDs do not support such features. To determine whether such
features has been implemented in the IED, check the hardware and software ordering codes
on the nameplate on the IED.
Chapter Installation and replacement shows how to identify the codes (→page 913). See also
Appendix: Ordering (→page 1004) for them.
