Installation and operation recommendation
It is strongly advised to periodically carry out, (minimun every 2 years approximately), a few operation cycles on operating devices.
Outside normal conditions of use, (between -5°C and 40°C , absence of dust, corrosive gas, etc.), it is recommended to examine, with our Schneider Electric services centre, the steps to be taken, in order to ensure correct functioning of the installation.
After 6 to 12 month operations, we recommend you to check the busbars and MV cable connection tightening.It should be done with a calibrated torque spanner, adjust to lower torque compare to values indicated in page 4.
Operation and maintenance
The necessity of correct implementation of connections:
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.
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).
the switchgear’s resistance to ageing in an MV substation depends on 3 main factors:
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.
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.
If no problems are detected and if the busbars and cable connections haven’t been modified, it will not necessary to do again this check. In case of dismantling, the elastic washers must be change and replace by new ones supplied by Schneider Electric.
Our service centre is at your disposal at any time:
- To undergo an installation diagnostic,
- To offer you, if need be, suitable maintenance operations,
- To offer you maintenance contracts,
- to offer you adaptations.
b Version 3600 A / 4000 A: We strongly recommend that you clean the ventilation grids regularly (every 2 years):
A : standard grids B : grids on RHB version.
b A fan monitoring system must be installed with the cubicle control and monitoring devices. Permanent operation of the following must be guaranteed: - 1 fan for version 3600 A - 2 fans for version 4000 A.

Once the cables are energised, the voltage indicator lights should light up.
A: voltage presence indicator light (1 for each phase)B: connection points enabling a phase concordance unit to be connected.
The indication of a VPIS alone does not suffice to ensure that the system is de-energised: if the operation rules require this, then suitable voltage detectors in compliance with IEC 61243 must be used for this.
VPIS must not be used as a VDS (Voltage Detecting Systems).
Instruction for use
The definite “voltage presence” indication is ensured on the voltage range stipulated by IEC 61958.
