Power-Grid Specification; Power Supply – Short Circuit Capability; Measurements On Inverter Input And Output - EURA DRIVES E800 series Safety Instructions, Installation And Operating Manual

1) Common installation rules and safety information regarding EURA E800 inverters

Measurements on inverter input and output:

Current and voltage may have no sinus shaped waveform on inverters input/output side.
If improper testing instruments are used, the result may become inaccurate, or in worst case, the
inverter and/or the test instrument may become destroyed.
On input side, the current waveform is composed by fundamental and harmonics, while on output side
the voltage waveform is PWM modulated.
The used instruments must be able to handle the various signal waveforms. For simple
measurements, a high quality moving iron instrument could be suitable.

Power-grid specification:

The inverter is build for symmetric three phase power supply
systems, with voltage phase to earth/neutral not exceeding 300V.
A transformer can be used for adaptation to higher voltages.
For single phase inverters the maximum input voltage is 240V +15%,
400V class thee phase inverters can work up to 460V +15%.
Contact the inverter manufacturer, before connecting to unbalanced,
floating, or unsymmetrical power systems.
Power supply – short circuit capability
Input chokes (Uk=4%) are recommended to connect the inverter on a
power grid with high short circuit capability, this especially for
continuous operation.
If the power supply capability exceeds by 20 times the inverter power,
the use of chokes is mandatory.
The inverter manufacturer must be contacted in
case of any question, regarding this
safety/instruction manual, or if some parts have
not been fully understood.
Please ask before installing or placing on
operation the system.
This is mandatory, to avoid any risk for
machinery damage and/or personnel injury.
