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 804.90kW (for WH-SXC09D3E5/UX09DE5 and WH-SXC12D6E5/UX12DE5) 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 804.90kW.
• 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 for models:
WH-SXC09D3E5/UX09DE5 and WH-SXC12D6E5/UX12DE5 : 0.236 .
Please liaise with supply authority to ensure that the power supply 2 is connected only to a supply of that impedance or less.
• This equipment’s power supply 3 complies with IEC/EN 61000-3-12.
• This equipment’s power supply 3 shall be connected to a suitable supply network, with the following maximum permissible
system impedance Z
max
at the interface for models:
WH-SXC09D3E5/UX09DE5 and WH-SXC12D6E5/UX12DE5 : 0.464 .
Please liaise with supply authority to ensure that the power supply 3 is connected only to a supply of that impedance or less.
