    remarks on this manual

    Purpose

    This Technical Manual is for information only. It describes

    extension of an existing GHA double busbar switchgear, at choice to the ● left or right-hand side.

    replacement of a switchgear panel within a GHA double busbar switch- ● gear.

    The switchgear is not switched OFF completely for the individual assembly descriptions, but the busbar systems remain in operation as far as possible.

    For the sake of clarity, this manual does not include all information on the various assembly descriptions in detail. Neither can it take every imaginable instance of installation or operation into account.

    This Technical Manual only provides a general overview of the work to be performed in case of extension or replacement. In each case of extension, a detailed switchgear-specific workflow must be prepared upon consultation with the manufacturer. No extension or replacement must be performed on the basis of this Manual alone.

    Liability claims against the manufacturer cannot be based on this Techni- cal Manual!

    As our products are subject to continuous further development, we reserve the right to make changes regarding standards, illustrations and technical data.

    reference documents

    The following additional documents must be complied with:

    sales agreement with the stipulations regarding the switchgear-specific ● equipment and the legal details

    the switchgear-specific circuit diagrams / documentation ● Operating Manual GHA (no. AGS 531 44 ● 1-01) Assembly Instructions GHA (no. AGS 531 44 ● 6-01) the operating instructions for the devices installed in the switchgear ● (e. g. IVIS, devices in low-voltage cabinet)

    the assembly instructions of the manufacturer of the cable connection ● systems to be connected to the switchgear

    1 safety provisions

    This Technical Manual is for information only and is exclusively intended for specialist electricians who have proven experience in conjunction with

    the GHA series (training certificate) ● the applicable safety provisions ●

    ● Common regulations for high-voltage switchgear and control gear: IEC 62271-1

    The locally applicable accident prevention, operating and work instructions ● must be complied with.

    Installation: IEC 61936-1 / HD 637 S1 ● 1

    Operation of electrical equipment: EN 50110-1 ● 1 1 The national standards applicable in the country where the equipment is to be installed must be complied with.

    Before performing work on the panel, it is essential that you comply with the following instructions:

    Warning: Before starting work on high-voltage components, de-energize the system, verify it for zero voltage and earth the system in accordance with the applicable safety rules pursuant to EN 50110-1.

    Warning: After removal of covers, operator safety in accordance with IEC 62271-200 may be restricted if the appropriate part of the switchgear has not been isolated from the power supply.

    For the work described in this manual, operator safety from internal arcs in accordance with the IAC classification is not ensured. Thus, in the case of manual switching operations, persons may only be located directly in front of the panels.

    Optimum operator safety is only ensured if the switchgear is com- pletely disconnected from the power supply and earthed during extension or replacement of panels. Thus, attempts should be made to achieve this switch condition at all times.

    Warning: Before performing work in the drive area of the switchgear panels, switch off the supply voltage and prevent it from being switched ON again.

    Warning: There is a risk of injury when working on the drive mechanism. Be- fore commencing work, release the energy-storing device by

    the OFF-ON-OFF (Open/Close/Open) operating sequence on the – circuit-breaker

    closing the make-proof – busbar earthing switch.

    Warning! The top sides of the panels are not meant to be walked on. Persons may fall through them, get injured or may damage the panel. When work has to be performed on the panel top, temporarily position a solid base plate to step on.
