NOTICE
In order to ensure IP 65 protection and the required and declared conformity with the
domestic EMC standard a PHOENIX CONTACT type M12MS SACC-4SC SH plug
and a shielded cable must be used. The outer diameter of the connecting cable can
be max. 8 mm.
Failure to observe this can lead to damage to the inverter and therefore void the
warranty.
