
The equipment's power supply 1 complies with IEC/EN 61000-3-12 provided that the short-circuit power S
greater than or equal to 1200 kW (for WH-SDC12F6E5/UD12FE5) at the interface point between the user's
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 S

The equipment's power supply 1 shall be connected to a suitable supply network, having service current capacity
≥ 100A per phase. Please liaise with supply authority to ensure that the service current capacity at the interface
point is sufficient for the installation of the equipment.

The equipment's power supply 2 complies with IEC/EN 61000-3-12.

The equipment's power supply 2 shall be connected to a suitable supply network, with the following maximum
