Safety information
Strictly follow the company and international safety regulations.
Working in a high voltage environment requires serious approch to
aviod human injuries and damage to equipment
Do not touch any circuitry during operation. Potentially lethal
voltages and currents are present
Avoid to touching the circuitry when covers are removed. The IED
contains electirc circuits which can be damaged if exposed to static
electricity. Lethal high voltage circuits are also exposed when covers
are removed
Using the isolated test pins when measuring signals in open circuitry.Potentially lethal voltages and currents are present
Never connect or disconnect wire and/or connector to or from IED
during normal operation. Dangerous voltages and currents are
present. Operation may be interrupted and IED and measuring
circuitry may be damaged
Always connect the IED to protective earth regardless of the

operating conditions. Operating the IED without proper earthing may
damage both IED and measuring circuitry and may cause injuries in
case of an accident.
Do not disconnect the secondary connection of current transformer
without short-circuiting the transformers secondary winding.
Operating a current transformer with the secondary winding open will
cause a high voltage that may damage the transformer and may
cause injuries to humans.
Do not remove the screw from a powered IED or from an IED
connected to power circuitry. Potentially lethal voltages and currents
are present
Using the certified conductive bags to transport PCBs (modules).
Handling modules with a conductive wrist strap connected to
protective earth and on an antistatic surface. Electrostatic discharge
may cause damage to the module due to electronic circuits are
sensitive to this phenomenon
Do not connect live wires to the IED, internal circuitry may be
damaged
When replacing modules using a conductive wrist strap connected to
protective earth. Electrostatic discharge may damage the modules
and IED circuitry
When installing and commissioning, take care to avoid electricalshock if accessing wiring and connection IEDs
Changing the setting value group will inevitably change the IEDs
operation. Be careful and check regulations before making the
change

Chapter 1 IED Introduction
2
The Human Machine Interface (HMI) on the IED provides an ideal
mechanism for the day to day operation and even advanced use of the IED.
The keyboard, LCD and LEDs on the front of the IED are what constitute the
HMI. Troubleshooting, monitoring, setting and configuring are all possible via
this interface. Through the screens and menu elements available, as well as
the keypad, the user is able to navigate throughout the menu structure and
move from screen to screen.
The IED is unpacked and visually checked. The connection to the protection
system has to be checked in order to verify that the installation is successful.
The settings for each function must be calculated before the commissioning
task. The functions setting menu have been listed in detail so that the user
can find and change the required settings directly and correctly. For the
different application, the IED can be performed conveniently throughswitching the setting group.
For the functions included in the IED can be tested by users, the testing
procedure have been listed as reference to verify that protection function
operate correctly.
After the IED is in service, some checking items also need to be done for
maintenance in order to ensure that the IED is in good condition during
operation, some suggestions have been preset as reference and the user can
perform some other checking items according to the relevant regulations.

rear of the IED.
Procedure:
1. Connect wire to the female connector
All wiring to the female connector should be done before it is plugged into
the male part and screwed to the case. The conductors can be of rigid
type (solid, stranded) or of flexible type.
The female connectors accept conductors with a cross section area of
0.2-1.5 mm2 (AWG 24-15). If two conductors are used in the same
terminal, the maximum permissible cross section area is 0.2-0.8 mm2
(AWG 24-18, each conductor corresponding to one cross section area).
If two conductors, each with area 1.5 mm2(AWG 15) need to be
connected to the same terminal, a ferrule must be used to combine the
two conductors, no soldering is needed.
Press the locking button by screwdriver to insert the wiring with ferrule
into the connector, move away the screwdriver after the ferrule has been
inserted into the connector completely to lock the wiring tightly. The follow
picture illustrates this process.
