When the cabinet needs C2 EMC compliance, do I add an external filter?

Dedicated industrial supplies fall under EMC Category C2. This unit ships with the C2 filter built in and tested at the factory, so there is no external filter module to source or wire — an unfiltered variant would push that cost onto your build.

Does my PROFINET network connect without a gateway?

PROFINET and EtherNet/IP are onboard, so the drive joins an industrial-Ethernet controller as a native node — no gateway. For legacy PROFIBUS DP use the PROFIBUS variant; for serial or building buses use the USS/Modbus/BACnet variant.

What overload rating applies to pump and fan duty?

Pump and fan loads are variable-torque, so the drive is rated at Low Overload: 110% of rated current for 60 s. At 1.1 kW that is 3.0 A continuous with headroom for start-up surges, in a 73 x 232 x 209 mm IP20 frame that mounts directly in the cabinet.
