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
sc
is
greater than or equal to 1100 kW (for WH-SHF09F3E5/UH09FE5 and SHF12F6E5/UH12FE5) 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
sc
greater than or equal to 1100 kW.

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
max
at the interface of the point: 0.244 Ω . Please liaise with supply authority to
ensure that power supply 2 is connected only to a supply of that impedance or less.
