When a 0.55 kW conveyor zone needs functional safety without a separate safety cable, this distributed SINAMICS G115D mounts in IP65/IP66 with PROFINET and PROFIsafe on one cable.

Its IP65/IP66 (UL Type 4X) enclosure and -30 to +55 C range let it sit through coolant spray, washdown and cold-storage duty without a protective housing. At 0.55 kW it delivers 3.4 A from a 380-480 V three-phase supply in a 380 x 156 x 129 mm FSA frame.

How is STO wired on this variant?

PROFINET and EtherNet/IP are onboard, and PROFIsafe carries STO over the same cable as the control data — there is no separate safety wiring run back to the cabinet. The AS-Interface and local-I/O variants provide STO via hardwired safety inputs instead.
