2.8 Technical data of electrical control and operating devicesThe switchgear panels have been designed on principle so as to permit manual operation.The drive mechanisms of the individual switching devices can be equipped, depending on the specific customer’s model, with additional electrical control and operating devices. These are defined in the switchgear-specific circuit diagram (see switchgear documentation).Component fitting options:

■ Motor drivefor actuation of the earthing switch

■ Blocking coilThe blocking coil prevents manual actuation of the earthing switch. If the supply voltage has failed or is shut off, all blocking coils are in ”blocked” position.

■ Auxiliary switchesAuxiliary switches are always actuated directly by the truck or by the switch shaft via an intermediate linkage. Their position always corresponds to that of the main contacts. The switching functions have been set in the factory according to the circuit diagram.

■ Micro switchesare used depending on the customized panel models.

5.1 Safety provisionsThe switchgear panels may only be installed and assembled by the manufacturer’s staff or by persons who have been certified for this work.PIX High panels are delivered with the earthing switch ON.In the case of panels with a width of 800 mm, the trucks can be delivered within the panels. They are in ”disconnected” position. The circuit breakers are always shipped in open state (”OFF”) with the energy storing device released.

Warning!Risk of injury due to movable parts in mechanical drives. The circuit-breaker’s energy storing device and the earthing switch must not be tensioned during assembly.Warning!Risk of accidents! Watch out for floor openings in the switchgear roomWarning!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 - e.g. assembly of deflectors, fans or pressure relief ducts - temporarily position a solid base plate to step on.Warning!Risk of injury in case of non-compliance with the safety instructions on page 6.

5.2 Important instructions for assemblyImportant: - Condensation, dirt and dust during assembly should be avoided

on all accounts, in order to prevent damage to the panels. - For assembly, observe the assembly drawings supplied with the

equipment. Read them before you commence assembly work. The drawing numbers are specified in this manual in the description of the assembly work in question. - For all screw connections, refer to the tightening torques specified

10.12 Panel with fan attachmentBus section couplers with circuit-breaker truck HVX or incoming feeder panels can be equipped on their top with a fan attachment for ventilation and consequently for cooling the circuit-breaker compartment (Fig. 128). This ventilation system is used for circuit breakers with high currents or in case of ambient temperatures ≥ 40 °C. The fan is switched on automatically if the current exceeds an adjustable threshold (see Table).The ventilation system operates with a radial fan and is protected against accidential contact. The service life of the fan is approx. 30 000–40 000 hours, depending on the ambient conditions.Settings for ambient conditions in accordance with Chapter 2.5, page 15:

Air flow sensorTo ensure the required cooling effect, the fan is monitored by an air flow sensor located directly in the air outlet. If the air flow is interrupted, the sensor issues a signal.

Measures to be taken in case of failure of the fan ■ Reduce maximum normal current to the ON threshold of the fan (see

Table). ■ Contact the manufacturer’s Service Center. Replacement of the fan can

be performed by staff certified accordingly.Assembly drawing: AGS C73488-03

11 Maintenance (contd.)

11.3 CleaningWarning!Risk of injury: the drives must not be disassembled forservice and maintenance work.

To ensure the specified insulating level, the insulating components must be clean. On principle, cleanliness deserves utmost attention.When deposited dirt is detected, the panels must be cleaned in an expert fashion.When cleaning, make sure that the lubrication in the drive mechanisms is not removed. If the drive mechanisms are no longer sufficiently lubricated, new lubrication must be applied.

Use a dry cleaning cloth to remove slight soiling:Clean using a dry, lint-free cloth. Depending on the degree of soiling, replace cloth as often as necessary.

Use cleaning agents for severe soiling:Cleaning agent, 1 l can (see Chapter 12.1, page 86). The use of other cleaning agents is not admissible.

■ Wear protective gloves ■ Use cleaning agent according to manufacturer’s instructions ■ Soak the cloth thoroughly and wipe the insulating components. Keep

duration of exposure as short as possible. ■ Expose the cleaned surface to the air for at least two hours.

11.4 Avoiding condensationTo ensure the specified insulating level, the switchgear panels – especially their insulating components – must not be exposed to condensation.

Measures to take in case of condensation: ■ Should condensation be detected in or on the panels, clean the panels in

accordance with Chapter 11.3, page 83). ■ Installation or inspection of panel heating. It must provide a sufficient

heating performance to prevent condensation on the panels. ■ Condensation can also be prevented by ensuring suitable ventilation and

heating of the station or by using de-humidification devices.

11.5 Corrosion protectionDrive mechanisms and covers have a long-term protection against corrosion.Any damage to the paint, scratches and other damage must be repaired immediately to avoid corrosion.

11.6 Replacement of components and panelsThe drive mechanisms, current transformers and voltage transformers as well as the testing and monitoring systems can be replaced if necessary. Also, entire panels can be replaced.Should you have any queries regarding replacement of components or panels, please contact the manufacturer’s Service Center.The data on the nameplate are relevant for replacement of components or panels or in case of any queries (see also Chapter 2.7, page 16).
