Max. permitted impedance in the mains connected point in accordance with EN 61000-3-11. Start currents can cause short voltage dips
that could affect other equipment in unfavourable conditions. If the impedance in the mains connection point is higher than that stated
it is possible that interference will occur. If the impedance in the mains connection point is higher than that stated check with the power
supplier before purchasing the equipment.
