This is a mechanical accessory, not an active electronic component — its job is cable management and strain relief within the starter assembly, keeping the communication and power wiring organized and secured against vibration in the panel. ## What It Does in the System In a SIRIUS compact starter installation, this mounting plate serves as the physical interface between the starter and the cable harness. It holds the shaped cable for AS-i — the flat, keyed cable that carries both power and data for the AS-i bus — and the separate auxiliary power cable. This keeps the wiring from pulling on the connector pins and maintains the bend radius specified for AS-i cable, which is critical for signal integrity on a bus that can run at up to 100 m segment lengths. The plate mounts directly to the starter housing, so it adds no extra DIN-rail width.","metaTitle":"Siemens 3RK1902-0AP00 Mounting Plate, AS-i & Aux Power Cable","metaDescription":"Siemens SIRIUS mounting plate for compact starter, holds shaped cable for AS-i and auxiliary power.
