Siemens 6FC5348-0AA02-0AA0 dual fan and battery module for Sinumerik and Simotion controllers. Manufacturer: Siemens. Part Number: 6FC5348-0AA02-0AA0. Product Type: combined cooling fan and backup battery module. Fans: 2. Batteries: 2, supplied with the module. Controller Platform: Sinumerik 840D sl NCU 710.1, NCU 720.1 and NCU 730.1, and Simotion D445-1 and D4x5-2. Mounting Type: clips into the front of the NCU housing. Item Weight: 0.28 kg (0.62 lb). Regulatory: declared under REACH Article 33 as containing 1,2-dimethoxyethane (EGDME).
6FC — the Siemens order-number group for Sinumerik CNC control equipment.
5348 — the fan and battery module family for the NCU control platform.
0AA02 — the execution code fixing the dual-fan version for the NCU 7×0 and D4x5 units.
0AA0 — the product-version suffix Siemens uses across the range.
Fans: 2. The pair draws air through the NCU housing and holds the processor and drive electronics inside their thermal envelope, which is what lets an NCU sit in a closed cabinet at full load.
Batteries: 2. The cells hold the NCU’s retentive memory and real-time clock while the control is powered down, so machine data, part programs and offsets survive a shutdown or a supply failure.
Controller Platform: NCU 710.1, 720.1, 730.1, D445-1 and D4x5-2. One module serves the whole NCU 7×0 range and the Simotion D counterparts, so a single spare covers a mixed shop floor.
Mounting Type: front-clip module. The unit is a serviceable item designed to be changed from the front of the control without dismantling the NCU, which is why fans and batteries are combined into one part.
Mounting Type: clip-in module on the front face of the NCU housing. Item Weight: 0.28 kg (0.62 lb).
Unit Quantity: 1 Pc. One module, containing two fans and two batteries.
MPN Variants: 6FC5348-0AA02-0AA0, 6FC53480AA020AA0, 6FC5348 0AA02 0AA0.
Within the 6FC5348 family the trailing execution code fixes the fan count and the controller range it fits. Match on the full order number.
