11.3.4.2 Connecting Requirement
The equipment's power supply 1 complies with IEC/EN 61000-3-12 provided that the short-circuit power S is
sc
greater than or equal to 828.38kW (for WH-SDF07C3E5/UD07CE5** and WH-SDF09C3E5/UD09CE5**) 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 greater than or equal to 828.38kW.

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
permissible system impedance Z at the interface for models:
max
WH-SDF07C3E5/UD07CE5** and WH-SDF09C3E5/UD09CE5**: 0.236Ω
Please liaise with supply authority to ensure that the power supply 2 is connected only to a supply of that
impedance or less.
