For hydrokit WH-SDC0305J3E5 or WH-SDC0709J3E5:
● The equipment’s power supply 1 complies with IEC/EN 61000-3-2.
● The equipment’s power supply 1 complies with IEC/EN 61000-3-3 and can be
connected to current supply network.
● The equipment’s power supply 2 complies with IEC/EN 61000-3-2.
● The equipment’s power supply 2 complies with IEC/EN 61000-3-11 and shall be
connected to suitable supply network, with the following maximum permissible system
impedance Z
max
= 0.352 Ω at the interface. Please liaise with supply authority to
ensure that the power supply 2 is connected only to a supply of that impedance or
less.
For hydrokit WH-SDC12H6E5 or WH-SDC16H6E5:
● 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 2,200 kW at the interface point
between the user’s supply and the public system. It is the responsible 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
short circuit power S
SC
greater than or equal to 2,200 kW.
● The equipment’s power supply 1 complies with IEC/EN 61000-3-11 and shall be
connected to a suitable supply network, having service current capacity ≥ 100 A per
phase. Please liaise with supply authority that the service current capacity at the
interface point is su󰀩cient 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 complies with IEC/EN 61000-3-11 and shall be
connected to suitable supply network, with the following maximum permissible system
impedance Z
max
= 0.271 Ω at the interface. Please liaise with supply authority to
ensure that the power supply 2 is connected only to a supply of that impedance or
less.
For hydrokit WH-SXC09H3E5 or WH-SXC12H6E5:
● 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 1,700 kW at the interface point
between the user’s supply and the public system. It is the responsible 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
short circuit power S
SC
greater than or equal to 1,700 kW.
● The equipment’s power supply 1 complies with IEC/EN 61000-3-11 and shall be
connected to a suitable supply net work, having service current capacity ≥ 100 A per
phase. Please liaise with supply authority that the service current capacity at the
interface point is su󰀩cient 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 complies with IEC/EN 61000-3-11 and shall be
connected to suitable supply network, with the following maximum permissible system
impedance Z
max
= 0.271 Ω at the interface. Please liaise with supply authority to
ensure that the power supply 2 is connected only to a supply of that impedance or
less.
For hydrokit WH-SDC09H3E8, WH-SXC09H3E8 or WH-SQC09H3E8:
● The equipment’s Power Supply 1 complies with IEC/EN 61000-3-2.

connected to current supply network.
● The equipment’s Power Supply 2 complies with IEC/EN 61000-3-2.
● The equipment’s Power Supply 2 complies with IEC/EN 61000-3-11 and shall be
connected to suitable supply network, with the following maximum permissible system
impedance Z
max
= 0.426 Ω at the interface. Please liaise with supply authority to
ensure that the power supply 2 is connected only to a supply of that impedance or
less.
