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
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
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.
