Safety and application instructions andinformation for drive converters

Safety and application information for drive converters(according to: The Low-Voltage Directive 73/23/EC)

SIMOVERT MV drive converters are medium-voltage drive converters. However,they use components which are subject to the Directives for low-voltage devicesand equipment. These include auxiliaries as well as open-loop and closed-loopcontrol components.

1. General information

During operation, in accordance with their degree of protection, drive converterscan have parts and components which are live (under voltage), bare and which aremoving or rotating; they can also have hot surfaces.

There is a potential danger of severe personnel injury or significant material

damage if the required covers are inadmissibly removed, if the equipment isincorrectly used or it has been incorrectly installed or controlled.

Please refer to the documentation for additional information.

Only suitably qualified, trained personnel may be used to transport, install andcommission as well as service/maintain the equipment (observe IEC 364 andCENELEC HD 384 or DIN VDE 0100 and IEC Report 664 or DIN VDE 0110 andthe domestic accident prevention regulations).

Qualified, trained personnel in the sense of this basic safety information arepersonnel who are knowledgeable about the installation, mounting, commissioningand operation of the product and are suitably qualified for the activities which theycarry-out.

2. Correct use

Drive converters are components which are designed to be installed in electricalplants or machines.

When they are installed in machines, it is not permissible to commission the driveconverter (i.e. go into correct operation), until it has been clearly identified that themachine is in full compliance with the regulations specified in EC Directive89/392/EC (Machinery Directive); EN 60204 must be observed.

Commissioning (i.e. go into correct operation) is only permitted if the EMC Directiveis maintained (89/336/EC).

The drive converters fulfill the requirements of the Low-Voltage Directive 73/23/EC.The harmonized Standards, series EN 50178/DIN VDE 0160 in conjunction withEN 60439-1/DIN VDE 0660 Part 500 and EN 60146/DIN VDE 0558 are applied forthe drive converter.

The technical data as well as the data on the supply/connection conditions shouldbe taken from the rating plate and the documentation. It is important that this datais carefully maintained.

3. Transport, storage

The information/instructions for transport, storage and correct handling of the driveconverter must be carefully observed.

Climatic conditions must be maintained in compliance with EN 50178.

4. Mounting

The drive converters must be installed and cooled corresponding to thespecifications in the associated documentation.

The drive converters must be protected against inadmissible stressing. Especiallyduring transport and handling, it is not permissible that components are bent and/orinsulating/isolating clearances changed. Electronic components and contactsshould not be touched.

3.5 Cooling water

When operational, the conductivity of the cooling water in the drive converter isautomatically kept at the required value using the ion exchanger in the coolingsystem. If the drive converter cooling water was drained, e.g. due to repair work,then only de-ionized water must be used to re-fill it (data, refer to the Descriptionof SIMOVERT MV).

The de-ionized water is filled through the cooling system.

A vent valve is provided at each vertical group pipe to vent the water circuit in thedrive converter.

Caution

When venting the drive converter it is not permissible that water sprays or dropsonto the drive converter components. Before the drive converter is powered-up, itmust be completely dry.A hose (8 mm diameter) must be screwed onto the vent valve (a connection is

provided on the valve) to vent air from the system. Use a container to catch anywater.

Refer to the Commissioning Instructions for the measures which are required to re-commission the drive converter (purge and vent reduce the conductivitycoefficient).

If the drive converter was accidentally filled with normal raw water, then the driveconverter may not be powered-up. Drain the water and remove any residual rawwater from all of the pipes and heatsinks by blowing nitrogen through the completesystem.

3.5.1 Draining the system

De-ionized water circuit

Warning

Please observe the safety information and instructions before draining the system(protect eyes, hands and body)! The system may only be emptied with the pumpsstationary and the voltages disconnected.

The de-ionized water circuit is emptied using the two drain valves in the coolingsystem. These are located at the lowest position in both the intake and return. Aftera suitable hose or similar is connected to the valve, the valve must be slowlyopened so that the pressure can slowly and continually decrease. All of the ballvalves in the de-ionized water circuit must be open. The vent valve at theequalization reservoir must be open. After a short time, the vents in the pipes mustbe opened. After the system has been emptied, all of the connections and ventsmust be correctly closed again.
