NOTE:
Cable cross-sections apply to PVC insulations selected
according to the standard PN-HD 60365-5-52:2011 for
the installation made according to B2 and for length
up to 10 m (copper conductors, conductor temper-
ature 70°C, ambient temperature 30°C in the air). At
observance of selectivity of protection units, the stat-
ed cross-sections of cables supplying controllers and
inverters will only be protected against the effects of
short-circuit currents.
The diagram shows max cross sections of leads for
3x12kW.
Individual control wiring diagrams for applications are
attached to this OMM Manual.
