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.
•Residual voltage
Hazardous voltage can be present in the DC circuit just after switching off the DC power
supply. It takes approximately 30 seconds for the voltage to discharge.
•Fiber optic
CLASS 1 LASER PRODUCT.

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 (Short-bar)
Do not remove the short-wire/short-bar(s) connected to the frame earth (FG) at the terminal
block on the rear of cases.
•Electric wire between #35 - #37 on the power-supply terminal block
Make sure the wire is connected.
(Exception: This wire needs to be detached for performing the dielectric voltage test.)

•Disposal
This equipment contains neither expendable supplies nor parts that can be recycled. When
disposing of this equipment, the customer must contact an operator responsible for
industrial waste disposal, and request that the operator dispose of this equipment in
accordance with the local waste disposal regulations; otherwise the person who disposes
of this equipment may be punished under local regulations. When disposing of this
equipment is practiced by the customer acting on their own behalf, it must be done so in a
safe manner according to local regulations. For further information in terms of the disposal,
the customer shall contact to a local dealer and sales staff at Toshiba Energy Systems &
Solutions Corporation (Toshiba ESS, Japan).
This equipment contains neither expendable supplies nor recyclables.
•Plastics material
This equipment contains the following plastics material.
- ABS, Polycarbonate, Acrylic resins, Nylon 66, and others.
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.
