12.3.4.1 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 3050kW (for WH-SDC12C6E5/UD12CE5**, WH-SDC14C6E5/UD14CE5** and
WH-SDC16C6E5/UD16CE5**) 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 3050 kW.

The equipment’s power supply 1 shall be connected to a suitable supply network, with the following maximum
permissible system impedance Z
max
at the interface for models:
WH-SDC12C6E5/UD12CE5**, WH-SDC14C6E5/UD14CE5** and WH-SDC16C6E5/UD16CE5** : 0.244 Ω
Please liaise with supply authority to ensure that the power supply 1 is connected only to a supply of that
impedance or less.

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-SDC12C6E5/UD12CE5**, WH-SDC14C6E5/UD14CE5** and WH-SDC16C6E5/UD16CE5** : 0.236 Ω
Please liaise with supply authority to ensure that the power supply 2 is connected only to a supply of that
impedance or less.

The equipment’s power supply 3 complies with IEC/EN 61000-3-12.

The 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-SDC12C6E5/UD12CE5**, WH-SDC14C6E5/UD14CE5** and WH-SDC16C6E5/UD16CE5** : 0.464 Ω
Please liaise with supply authority to ensure that the power supply 3 is connected only to a supply of that
impedance or less.
