Outsidenormalconditionsofuse,(between-5°Cand40°C,absenceofdust,corrosivegas,etc.),itisrecommendedtoexamine,withourSchneiderElectricservicescenter,thestepstobetaken,inordertoensurecorrectoperationoftheinstallation.
After 6 to 12 month operations, we recommend you to check the busbars and MV cable connection torque.It should be done with a calibrated torque wrench, adjust to lower torque compare to values indicated in page 4.If no issues are detected and if the busbars and cable connections haven’t been modified, it will not be necessary to do again this check.
Operationandmaintenance
1/ The necessity of correct implementationofconnections:New cold retractable or slip-on technology offers ease of installation that favours resistance over time.Their design allows them to used in polluted environments with harsh climatic conditions.
2/ Impact of the relative humidity factor:Installing a heating device is essential in climates with high relative humidity levels and major temperature differences.Ensure that draughts and / or thermal shocks are avoided in all cubicle compartments in order to avoid the creation of dew points (sources of partial discharges).
Theswitchgear’sresistancetoageinginanMVsubstationdependson3mainfactors:
The equipment must be installed in conformity with the relevant IEC standard. Outside of these normal usage conditions, we recommend contacting Schneider Electric to determine the operations to be carried out as well as their frequency according to the actual service conditions.
3/ Electrical room ventilation control:Grid size must be suited to the power dissipated in the substation. These grids must be placed exclusively in the vicinity of the transformer, in order to avoid air circulation on the LV switchboard.
In case of disassembly, the elastic contact washers must be changed and replaced by new ones supplied by Schneider Electric.

To rack-in and rack-out the circuit breaker, the earthing switch must be operated.
At the installation of the FU, the electromagnetic locking is not yet enegised, it must be manually released in order to operate the earthing switch.
Initialstatus: - The earthing switch is closed,- Selector 4 is in the locked closed position.
Insert a screwdriver via the box hole.Disassemble the VPIS without disconnecting the wiring.
Open the earthing switch, inserting the crank in reference 5 until the mechanical indicator light changes status.
Push back and hold in place the electromagnet (A) using the screwdriver, then pull towards you and turn the selector to the right in the operation position.
Put back the VPIS.Position selector 4 in the locked open position.

Initialstatus:- The circuit-breaker is in the racked-out position.- The earthing switch is closed.- The front panel is disassembled to access cable connections.
The locking system is accessible as per the arrow in the drawing opposite.
Rack-inpreventionwithelectromagneticlocking
To access the cable connection compartment, circuit-breaker rack-in must be prevented.
At the installation of the FU, the electromagnetic lock is not energised, it must be manually released in order to place the front panel when the operations are complete.
Priortoinstallingthefrontpanels
If lever (A) is positioned as per figure1, locking is active and prevents installation of the front panel.
To desactivate the locking, insert a tool (screwdriver) into the hole placed under the box support and push the electromagnet rod (B).Push the lever (A) to position it as per figure2.The system is released and the front panel can be placed back.

DefeatingInterlocks
This procedure requires to defeat the interlocks.
It is essential to follow the sequences here after.
The insulation level of the switchgear can be tested on site. The test voltage shall be 80 % of the rated short-duration power-frequency withstand voltage of the switchgear as specified in clause 7.105 of IEC 62271-200.
This test can be carried out in one single operation.
All circuit-breakers must be racked-in, closed, with FU doors open.
All the VT’s and surge arresters must be disconnected during this test.
More over, one of the FU feeder must have its lower panel open to connect the test cable.

This operation has to be made during assembly of the tunnels (option) or during operation on the roof of the cubicle.
The internal arcing detector is located on the roof of the cubicle.To be operational, it must be in spring loaded position.
Setting up the internal arcing detector:
- Push the metal rod (1) toward the back of the cubicle,
- Hook the rod (1) on the support (2).
1: metal rod,2: support.
(1) The internal arcing detector is mounted according to the internal arcing withstand characteristics of the cubicle.
