main bus terminal using eld regulators and tighten the bolts
with 50Nm torque.
3. Wipe the insulators and solid insulation materials with a dry
clean cloth.
4. Assemble the upper cover plate.
IMPORTANT WARNING: If the surface
on which the cubicles will be mounted
is not at, the cubicles’ covers may not
be tted properly and also problems
may be caused in the main busbar
connection.

Connect the grounding busbar points of the two adjacent
cubicles with a copper conductor that is already provided with
the cubicle using bolts as shown in the right picture (3).
GROUNDING
CONNECTION
POINT
• To connect the cubicle’s array to the facility’s main
grounding system, use the grounding busbar located in the
cable connection compartment of the cubicles. See Picture
(4).
• Any of the cubicles at the beginning or at the end of the
cubicle’s array can be used for this purpose.
3.6 – EARTHING BUSBARS CONNECTION
3.7 - CONNECTING THE CUBICLES› ARRAY TO THE MAIN GROUNDING SYSTEM
OF THE FACILITY
IMPORTANT WARNING: Check thoroughly that the
grounding busbars of all the cubicles found in the
cubicle’s array are connected to each other.

3.8 –PASSAGES OF AUXILIARY SERVICE AND CONTROL CABLES FROM CUBICLE TO
ANOTHER
• The sockets in the LV cabinet are used for the passage of
auxiliary service and control cables from cuibcle to another.
See the left picture (5).
• Take either the female or the male socket found on the
cable passage hole in the LV cabinet and connect it to its
corresponding socket found on the cable passage hole of
the next cubicle. See the left picture (6).
NOTE: The connection between cubicle to another
is made by combining the cable entry sockets that
contain the electrical interlock and AC-DC cables
to each other.
NOTE: The cable passage hole found at the very beginning or at the end of the cubicle’s array is used
for the passage of the auxiliary service, control and command cables coming from the external power
supplies.
IMPORTANT WARNING: If there is a battery rectier
group in the facility, ensure that is connected to a 220 /
230 VAC source.

3.9 - CONNECTION OF MV CABLES
3.10- MATTERS TO BE CONSIDERED AGAINST INTERNAL ARC WHEN THE CUBICLE IS
MOUNTED
MV CABLES CONNECTION
MV Cables are made according to the cable terminal cap instructions.
The plastic plugs found at the cubicle’s bottom surface should be
adjusted in accordance with the cables diameter so to enable the cables
from passing through them. See picture (8).
1. Open the cubicle’s cable connection compartment door.
2. Mount the cable terminal caps ( internal type ) on the MV cable
terminals in accordance with the related instructions.
3. Connect the mounted terminals to the cubicles’s output terminals.
See picture (7).
4. Connect the metallic screen of the MV cables to the cubicle’s
earthing busbar.
5. Fix the MV cables by using the cable supporting points located on
the MV cables’ entrance of the cubicle. See pictutre (8).
Close the cubicle’s side by cover plates before the operating.

4.1 - CHECKS TO BE PERFORMED BY THE BARE EYE (Checks to be Performed While the Main
Busbar is De-energized)
4.2 - MECHANICAL CHECKS (Checks to be Made in This Section Should Be Performed While
the Main Busbar is De-energized.)
IMPORTANT WARNING: Never connect the MV cables connected to the output terminal in a way that will
force the output terminals to pull down.
4 - COMMISSIONING
If a cubicle array will be formed by arranging various types of MMMH cubicles side by side and the commissioning
wil be performed for the rst time, it is recommended by our company to apply the following procedure:
1. Check whether the connections of the cubicles’ main busbar are connected along with the disconnector or the
load break switch or not and tighten the loose bolts and nuts if required. While checking the connectivity, be
careful from damaging the bushings of the disconnector or the load break switch. Never step or walk on the
busbar, disconnector or the load breaker switch
1. Perform “Commissioning”, “De-commissioning” and the “Accessibility to Cable Connection Compartment” for
each cubicle in accordance with the operating instructions sticked on them. During that, check the mechanical
interlocks are operating properly and no problems are occured.
2. Please contact EVA ELEKTROMEKANİK on (0090 312 811 2727) if any problem is encountered during the above
points.
2. Check if there is any unusual object inside the cubicle and take it out.
3. Check that there is at least 100 mm gap between the cubicles’ back and the building’s wall and that there is no
objects in between.
4. Check whether the side cover plates used against the internal arc are xed, if not x them so.
5. If there is a battery rectier group in the facility, ensure that is connected to a 220 / 230 VAC source.
6. Ensure the grounding system of the cubicles by checking the grounding busbars of the cubicles’ array
which must be properly and tightly connected to each other. Also, ensure the cubicles’ grounding system by
checking the earthing busbar of the rst or the last cubicle which must be connected to the external earthing
system by an earthing conductor.
7. Check the connections of the LV cabinet.
4.3 - SUPPLYING VOLTAGE TO THE MAIN BUSBAR AND REQUIRED CHECKS
4.4- OPERATING THE CABLE CONNECTION CUBICLE
4.5- SHUTTING DOWN THE CABLE CONNECTION CUBICLE
1. By Switching o the switching elements of the incoming cubicle, energize the main busbar and wait for 90 to
120 minutes.
2. Ensure that the voltage indicators lamps of the incoming cubicle are o.
3. If no problems were observed then energize the cubicles one by one as stated below.
4. After energizing the cubicle’s array, check whether if there is unusual noise or not.
1. If the Cable Connection Compartment door of the Cable Connection Cubicle is Open, CLOSE it.
2. Switch o the output feeder feeding the cubicle.
3. Ensure the voltage indicator lamps are on.
1. Switch on the output feeder feeding the cubicle.
2. Ensure the voltage indicator lamps are o.

5.1-MAIN BUSBAR COMPARTMENT
1. Check whether the connections of the cubicles’ main
busbar are connected along with the disconnector or
the load break switch or not and tighten the loose bolts
and nuts if required. While checking the connectivity, be
careful from damaging the bushings of the disconnector
or the break switch. Never step or walk on the busbar
and the disconnector or the load breaker switch.
To nd the main busbar, remove the bolted connections
