1. RECEPTION & INSTALLATION
1.1.Relay unpacking
Previously to any handling action, confirm
that relay carton box is in good conditions,
no broken or damaged due to external
manipulation or during storing or moving
process. If packing is correct, proceed to
unpack and you should find following
element:
•SIAB Electronic protection relay.
•User Guide.
•Testing protocol.
Testing protocol is a certificate that relay has passed all factory testing process with correct
results.
In case some fault is detected, consider putting into quarantine period the relay and contact
Fanox for further instructions.
1.2.Relay verification
When relay is unpacked, please, take your
time to confirm following checking list to be
sure that everything is ok:
•Metallic case not damaged and well
assembled. No loose screws due to
transport or movement conditions
•LCD and front cover not damaged
or scratched.
•Quality sticker and terminal sticker
correctly stuck.
•Rear terminals in good state, being
able to do a good wiring
connection.

1.3.Powering the relay up
Thanks to the external battery KITCOM the powering and adjusting process of the relay is very
easy and it allows the user to test the relay.
The power comes from two AA batteries (IEC LR06) of 1.5 Volts placed at the bottom of the
kitcom. The equipment has a small Dc/Dc power supply that raises the voltage till the required 5
volts to operate the equipment and that is plugged into the front USB communications port
(KITCOM).
Once the KITCom is connected, the relay will be switched on and a led on the left of the relay
(led on) will blink indicating the relay is powered on through an external battery (KITCOM).
The relay is totally maintenance free. This is, there is no need of batteries to log events and
fault reports and there is no need of batteries to maintain date and time.
NOTE: Date and time must be correctly set the first time the relay is operative.
Besides, the possibility of using external
battery power, together with the possibility
of activating the trip contact from the test
menu, allows the trip circuit to be tested
before the transformation center is powered
up. So, the KITCOM is useful for cases like
commissioning operations, discharges and
repairs to the transformation center.
Using battery power does not block the
USB communications port, as it can be
used simultaneously.
Once the relay is powered through the Kitcom, it should be checked:
•Model→Directly, complete model
on top line and phases/neutral
current measurement on bottom
line are displayed. Once “C” key is
pressed the name of phase and
neutral currents (instead the
complete model) is displayed on
the top of LCD Standby screen.
•Serial number (8 digits) and
Firmware Version →HOLD

•Use KEYPAD to ensure that all the
push-buttons work correctly (no
difficulties while pushing them,
check out if the relay reacts by
pushing each of the buttons)
•Use KEYPAD to enter in the relay´s menu and make sure that no text is lost while going
from one menu to another.
•Follow the sequence: Left ◄, Down
▼, Right ►, Up ▲, OK, C and
RESET and the following screen
should be displayed:
•If the contrast of the LCD is not the
correct one, enter to “CONTRAST”
menu by holding “◄” for 3 seconds.
Then, change it by using up and
dwon buttons to increase or
decrease the contrast.
1.3.1.Test menu
NOTE: When performing test menu,
protection won´t be available and it will be
possible to open circuit breaker. Only
authorized personnel can do this job.
Press ◄,▼,► sequentially and hold OK.
The relay will ask for the password “5555”
to enter to the test menu (or customer
password if default “5555” has been
modified).
Once the password is entered, check that
all the LEDs are switched on at the same
time. Then press OK key to start the test
menu.
It will be checked that the Outputs are
activated if OK key is pressed and it will be
deactivated if OK key is pressed again.
LEDs and outputs will be checked to verify
the hardware is OK:

1.4.Relay intallation
To fix the relay to the switchgear, use default holes in front of relay with appropriate fixing
system. Do not manipulate relay to fix it on the switchgear.
How to change the internal battery (DEPENDING ON MODEL)
1. Disconnect the relay. Switch the power supply off to avoid any dangerous situation.
2. Unscrew the 4 screws on the front of the relay to extract it from the RMU and access to the
rear side of the relay.
3. Unscrew the 2 screws to remove the cover from the battery compartment.
4. Remove the battery and replace it respecting polarity (+ facing up):
Battery characteristics:
•AA 3.6V lithium battery
•Model LS14500 from SAFT
•Do not use rechargeable batteries or other types of battery

5. Put on the battery cover and tighten the 2 screws.
6. Put the relay into the RMU again and tighten the 4 screws on the front to fix the relay.
Warning HAZARD OF EXPLOSION
•Do not recharge the battery.
•Do not short circuit the battery.
•Do not crush the battery.
•Do not disassemble the battery.
•Do not heat the battery above 100ºC (212ºF)
•Do not throw the battery into fire or water.
Failure to follow these instructions can result in death, severe injury, or equipment damage.
