The below Installation guide is limited applicable only for model
Model : ARUB200DT3, ARUB180DT3
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to 4723 kVA
at the interface point between the userʼs supply and the public system. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected
only to a supply with a short-circuit power Ssc greater than or equal to 4723 kVA.

This device is intended for the connection to a power supply system with a maximum permissible system impedance
Z
MAX
of ohm at the interface point (power service box) of the userʼs supply.
The user has to ensure that this device is connected only to a power supply system which fulfills the requirement above.
If necessary, the user can ask the public power supply company for the system impedance at the interface point.
The value of can be chosen by following.
