Please read the whole manual carefully before working on the switchgear.

Metal-enclosed AC switchgear for rated voltages > 1 kV up to including 52 kV:IEC 62271-200

Use and handling of sulphur hexauoride (SF6) in high-voltage switchgear: IEC

62271-303

The locally applicable accident prevention, operating and work instructionsmust be complied with.

Installation: IEC 61936-1/EN 61936-11

Operation of electrical equipment: EN 50110-11

1The national standards applicable in the country where the equipment is to beinstalled must be complied with.

Before performing work on the panels, it is essential that you comply with the follow-ing instructions:

Danger!

Risk of fatalities due to high voltage. Isolation from high voltage

and earthing must always be ensured before performing assembly

or maintenance work.

Danger!

Risk of fatalities due to supply voltage. Isolation from supply

voltage must always be ensured before performing assembly or

maintenance work.

Warning!Risk of injury due to movable parts in mechanical drives. For

maintenance work,

isolate the system from the supply voltage

release the circuit-breakers energy storing device by OFF-ON-OFF operation and make-proof earthing switches by the

appropriate ON-operation.

Warning!

After removing covers from a switchgear unit, operator safety

may be reduced regarding internal arcs unless the switchgear is

isolated from the power supply. Optimum operator safety is only

ensured if the switchgear is completely disconnected from the

power supply and grounded during assembly.

For the case of an internal fault, the GHA switchgear features pressure relief portswhich prevent the panels and the switchgear from bursting.

This Technical Manual does not include information regarding the safety of buildingsin case of internal faults (pressure load of the switchgear room and necessary pres-sure relief ports). Pressure calculations for switchgear rooms incl. recommendationsregarding pressure relief ports can be provided on request against a fee. For furtherdetails, please contact the manufacturer.

In case of re or of internal faults, toxic and caustic decomposition products may beproduced. Comply with the locally applicable accident and safety provisions.

In case of personal injury, take rst-aid measures or cause them to be taken.

8 Switchgear with pressure reliefdevice

8.1 Overview

Switchgear units with pressure relief duct are accessible on all sides and can thus

be located centrally in the room.

Important: The pressure relief duct must be mounted before the panel is

positioned on the base frame (see Chapter 4.5, page 28). After

installation of the panels, mounting is no longer possible.

The customized pressure relief duct and the pressure relief apare included in the scope of supplies.

The attachments for the pressure relief duct are included in the accessories.

The pressure relief ducts and the side walls are attached on the construction site.
