5.2 Drive system on the mains

These information apply to the drive s ystem, consisting of:

ƒ ECSxExxx power supply module

ƒ ECSxKxxx capacitor module

ƒ ECSxAxxx axis module

ƒ Motor

ƒ Accessories

ƒ Wiring

5.2.1 Supply form/electrical supply conditions

Please observe the restrictions for the respective supply forms.

Mains Operation of the capacito r modules Notes

With earthed neutral

(TT/TN systems)

No restrictions The capacitor module will be destroyed if

+UG conductor or -UG conductor are

earthed.

With isolated neutral

(IT systems)

The operation on symmetrical IT systems

with PE is permitted.

DC-supply via

+UG/-UG

Permitted if t he DC voltage is symmetrical

with PE.

The capacitor module will be destroyed if

+UG conductor or -UG conductor are

earthed.

5.2.2 Operation on public supply systems (compliance with EN 61000-3-2)

The European standard EN 61000-3-2 specifies limit values for limiting harmonic currents

in the supply system. Non-linear loads (e. g. frequency inverters) create harmonic currents,

which impair the supply system and thus may disturb other loads. The objective of this

standard is to ensure the quality of the public supply systems and reduce the mains load.

 Note!

This standard only applies to public supply systems. Supply systems with an

own transformer station which are standard in i ndustrial firms are not public

and are out of the scope of the standard.

If a device or machine consists of several components, the limit values of the

standard are applied to the entire unit.
