Panasonic WH-UD09CE5-A [57/146] Connecting requirement

12.3.4.2. Connecting Requirement

• The equipment’s power supply 1 complies with IEC/EN 61000-3-12 provided that the short-circuit power S

is greater than or

equal to 787.57kW (for WH-SDF12C6E5/UD12CE5**, WH-SDF14C6E5/UD14CE5** and WH-SDF16C6E5/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

greater than or equal to 787.57kW.

• 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-SDF12C6E5/UD12CE5**, WH-SDF14C6E5/UD14CE5** and WH-SDF16C6E5/UD16CE5** : 0.244Ω

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-SDF12C6E5/UD12CE5**, WH-SDF14C6E5/UD14CE5** and WH-SDF16C6E5/UD16CE5** : 0.236Ω

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-SDF12C6E5/UD12CE5**, WH-SDF14C6E5/UD14CE5** and WH-SDF16C6E5/UD16CE5** : 0.464Ω

Please liaise with supply authority to ensure that the power supply 3 is connected only to a supply of that impedance or less.
