Leakage and residual currents

Due to their principle of operat frequency inverters generate leakage currents. For the correct operation of the frequency inverter on a currentsensitive RCD, the use of an all-current sensitive earth leakage circuit breaker (Type B) compliant with EN 50178 / VDE 0160 is necessary.

Note

The frequency inverters are suitable for operation on TN or TT networks as configuration of the integrated mains filter.

Operation on TN- / TT- / IT- networks

Maintenance

In normal use, frequency inverters are maintenance free. The cooling surfaces must be regularly cleaned with c ompressed air if the ambient air is dusty. In case of long-term shut-down or long-term storage, the capacitors must be re-formed (refer to "Technical Data"). Failure to do this will damage these components and will cause a considerable reduction of the service life -

SK 500E – Brief instructions for frequency inverters

2. Assembly and installation

SK 500E frequenc y inverters are available in vari ous si zes depending on the outp ut . At tent io n must be paid to a suitable position when install ing.

The equipment requires sufficient ventilation to protect against overheating. For this the minimum guideline distances f rom adjacent components above and below the fr equency inverter, which could obstruct the air flow apply.

Distance from device: Mounting can be immediately next to each other. However, for the use of brake resistances m ounted belo w t he f reque ncy inverter (not possib le with … -CP devices), the greater width must be taken into consid eration, particularly in combination with temperature switches on the brake resistor!

Installation position: The installation position is nor mally vertical. It m ust be ensured tha t the cooling ribs on the rear of the frequency inverter are covered with a flat surface to provide good convection.

(above > 100 mm, below > 100 mm)

Warm air must be vented above the device!

Fig. 1 Mounting distances for SK 5xxE

If several inverters are arranged above each other, it must be ensured that the upper air entry temperature limit is not exceeded. ( See also Section 0 ) If this is the case, it is recomm ended that an "obstacle" (e.g. a cab le duct) is m ounted between the inverters so tha t the direct air f low (rising warm air) is impeded.

Heat dissipation: If the frequency inverter is insta lled in a control cabinet, adeq uate ventilation mus t be ensured. The heat dissipati on in operation is appr ox. 5% (according to the si ze and equipment of the device) of the rated power of the frequency inverter.

2.1 SK 5xxE, standard version

Normally, the frequency inverter is mounted directly on the rear wall of a control cabinet. For th is, two, or f or sizes 5 to 7, f our matc hing wall m ounting brackets are supplied, which are to be inser ted into the he at sink at the rear of the device. For size 8 and above, the mounting device is integrated.

Alternatively, for sizes 1 ... 4 the wall mounting brackets can be ins erted at the side of the cooling el ement in order to minimis e the necessary depth of the control cabinet.

In general, care m ust be taken that the rear of the cool ing e lement is covered with a flat surface and that the device is mounted vertically. This enables optimum convection, which ensures fault-free operation.

2.2.1 Wiring guidelines

The frequency inverters have been developed for use in an industrial environment. In this environment, high le vels of electr omagnet ic interf erence can act on the freque ncy inver ter. In gener al, correct installat ion ensures safe and problem-free operatio n. To meet the limitin g values of the EMC directives, the following instructions should be complied with.

1. Ensure that all equipment in the control cabinet is securely earthed using short earthing cables which have large cross-sections and are connecte d to a common ear thing point or earth ing bar. It is especially important that each control unit which is connecte d to the electronic drive technol ogy (e.g. an automatic de vice) has a short cable with a la rge cross-section, which is connected t o the same earthing point as the dfrequency inverter itself. Flat cables (e.g. metal stirrups) are preferable, as they have a lower impedance at high frequencies.

2. The bonding cable of the motor c ontro lle d by the frequency inverter s hou ld b e c on nected directly to the earthing terminal of the associated controller. The presence of a central earthing bar in the control cabinet and the grouping together of a ll bonding conductors to this bar normally ensures safe operation.

3. Where possible, shielded c ables should b e used for control c ircuits. T he shieldin g at the cable e nd should be caref ully sealed and it m ust be e nsured th at th e wires are not laid over longer distanc es without shielding.

The shields of analog setpoint cables should only be earthed on one side on the device.

4. The control cables should be i nstalled as far as possible from power cables, using s eparate cable ducts, etc. Where cables cross, an angle of 90° should be ensured as far as possible.

5. Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by free-wheeling diodes for DC contactors, for which the interference traps must be positioned on the contactor coils. Varistors for o ver-voltage limitation are also effective. This inter ference suppression is partic ularl y impor tant when the c ontactors are contro lled by the relay in the frequency inverter.

6. Shielded or armoured cabl es should b e used f or the load c onnect ions (m otor cable). T he shieldi ng or armouring mus t be earthed at both ends. If possible, earthing should be made directly to t he electrically conducting mounting plate of the control cabinet or the screening angle of the EMC Kit.

2.2.3 Electrical connections, power unit

Before connecting the frequency inverter, the following must be observed:

1. Ensure that the mains supply provides the correct voltage and is suitable for the current required.

2. Ensure that suitable circuit br eak ers with t he s pecified nom inal cur ren t range are instal led between the voltage source and the inverter.

3. Connect the mains voltage directly to the mains terminals L1-L2/N-L3-PE (for each device)

4. A four-core cable must be used to connect the motor. The cable is connected to the motor terminals PE-U-V-W.

5. If screened motor cables (recom m ended) are us ed, the c able scree ning m us t also be con nected to a large area of the m etallic screening angle of the EMC Kit, however, at least to the electricall y conducting mounting surface of the control cabinet.

6. Above size 8, the cable lugs which are included in the scope of delivery must be used. After crimping, these must be insulated with shrink hose.

Note

The use of shielded cables is essential in order to maintain the specified radio interference suppression level. If certain wire end sleeves are used, the maximum cross-section which can be connected can be reduced.

To connect the power unit, the following tools must be used:
