5.2 Drive system on the mains
These information apply to the drive system, 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 capacitor 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 the 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 industrial 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.
