Siemens 6FC5348-0AA01-0AA0 SINUMERIK/SIMOTION Fan and Battery Module
01Overview
Siemens 6FC5348-0AA01-0AA0 is the small SINUMERIK/SIMOTION fan and battery module for external heat dissipation. It includes a buffer battery and is identified for NCU 710, NCU 720 and NCU 730 control units; Siemens also lists it as an option for SIMOTION D425/D435 and as a spare part for D445. Because nearby 6FC5348 articles use different fan arrangements, the installed cooling concept and complete order number must be matched.
