2.1 Responsibilities

Our devices are quality controlledand tested at the factory in accor-dance with the standards and theregulations currently in force.Apparatus efficiency and appara-tus life depend on the compliancewith the installation, commission-ing and operation instructions de-scribed in this user manual. Nonrespect of these instructions islikely to invalidate any guarantee.

Local requirements especiallyabout safety and which are in ac-cordance with the indications given

in this document, must be ob-served.AREVA declines any responsibilityfor the consequences:

> due to the non respect of therecommendations in this manualwhich make reference to the in-ternational regulations in force.

> due to the non respect of the in-structions by the suppliers of

cables and connection accesso-ries during installation and fittingoperations,

> of any possible aggressive cli-matic conditions (humidity, pol-lution, etc.) acting in the imme-diate environment of the materi-als that are neither suitablyadapted nor protected for theseeffects.

This user manual does not list thelockingout procedures that mustbe applied. The interventions de-

scribed are carried out ondeenergized equipment (in thecourse of being installed) or lockedout (non operational).

2.2 Particular instructions for operations and interventions on energized equipment

When commissioning and operat-ing the equipment under normalconditions, the general safety in-structions for electrical applicationsmust be respected, (protectivegloves, insulating tool, etc.), in ad-dition to standard operating in-structions.

All operation must be completedonce started.

The durations (for completing theoperations mentioned) given in themaintenance tables are purely anindication and depend on onsiteconditions.

3 Functional interlocks

3.1 Functional mechanical interlocks

The MODULARC switchgear isequipped with internal mechanical

interlocks, called "functional", in-tended to avoid any kind of operat-ing error.

It is necessary to know these inter-locks in order to operate the

switchgear correctly.

5 Use of the CB function

The procedures here fol-lowing described refer toa line switchgear withmanual closing andopening controls. It will

be necessary to shift thedoor-es (earthing switch-ing) interlock, in order toinsert the lever.

> Act on the DOOR-ES interlock,by shifting it downwards.

5.1 Opening the earth ing switch

> Insert the operating lever intothe earthing switch control.

> Grasp the lever with both hands.

> Turn the lever counter-clockwise, up to reach the endof stroke. The mimic diagramindicator will turn from the

closed earth position to the

earth open position .

> Extract the operating lever.

5.2 Closing the earthing switch

> Act on the ES-D (earth switchingdisconnector) interlock, by shift-ing it upwards.

> Insert the operating lever intothe earthing switch control.


> Turn the lever clockwise, up toreach the end of stroke. Themimic diagram indicator will turnfrom the opened earth position

to the earth close position.


> Act on the DOOR-ES interlock,by shifting it upwards. Now it ispossible to open the door.

5.3 Closing the disconnector

> Act on the ES-D (earth switchingdisconnector) interlock, by shift-ing it downwards.

> Insert the operating lever intothe disconnector control.


> Turn the lever clockwise, up toreach the end of stroke.

8 Characteristics and Volumes of SF6gas

8.1 General characteris tics

Type of Insulating Gas:Sulphur Hexafluoride (SF6) iaw

IEC 60376.

Each switchgear comprises a tank,filled with SF6gas, designed as apressurised, sealed-unit system inaccordance with the requirementsof IEC 60694.

During the expected operating lifeand under normal operating condi-

tions the gas should not need top-ping up.

The GWP (Global Warming Poten-tial) of the SF6gas is 22,200.

Never pierce thepressurised tank!

Never attempt toopen the tank.

8.2 Filling pressure

At 20C the filling pressure is 0.030 MPa.
