1. Unboxing & Physical Snapshot
- Model & Brand: 6DD1682‑0CH0, Siemens SIMATIC‑TDC slide‑in fan tray for UR2, UR2‑H, UR6 subracks (obsolete OEM spare)SiemensPLC
- Physical Dimensions (Approximate W × H × D): 70 mm × 147 mm × 129 mm, dedicated slide‑in fan‑slot form‑factor for TDC subracksIndustry M…
- Estimated Shipping Weight: 1.87 lb (0.85 kg net unit weight; includes complete fan tray assembly, protective grille, integral wiring connector, static‑shield bag, foam‑reinforced carton)
- What’s in the Box: Complete TDC rack fan‑tray assembly, built‑in rear mating connector, OEM printed installation datasheet; host UR2/UR2‑H/UR6 subrack sold separately (verify mechanical fit, supply voltage and airflow direction before spare procurement to avoid commissioning delays for metallurgical, paper‑making and complex multi‑loop process‑control systems)
2. Product Introduction (Structure B – Architecture hook)
This 6DD1682‑0CH0 forced‑air cooling fan tray slides into the dedicated upper fan bay of SIMATIC‑TDC UR2, UR2‑H and UR6 subracks, delivering bottom‑to‑top directed convection cooling for CPU, communication and I/O Eurocard modules inside the control rackSiemensPLC. Fully seated rear connector contacts guarantee continuous airflow and thermal dissipation; incomplete seating or degraded fan performance elevates component junction temperatures and triggers unpredictable module thermal trips that mimic CPU or power‑supply faults within critical high‑performance process‑control strategies.
Reliability teams must validate full part‑number and hardware revision prior to spare rotation. Mechanically similar substitute fan trays exist with different supply‑voltage ratings and airflow capacities. A dimensionally‑fitting mismatched fan assembly inserts into the rack bay yet fails to deliver required cooling performance (a well‑documented outage risk within heavy‑industry continuous‑process facilities). No software parameter adjustment can compensate for insufficient rack cooling airflow.

5. Long‑Term Storage & Asset Preservation Guide
Store this fan‑tray assembly sealed inside its original ESD‑shield bag for warehouse shelf storage. Open static pouch exclusively at a properly‑grounded ESD workstation; avoid manual rotation of fan impeller during long‑term storage to prevent bearing pre‑stress.
Maintain storage‑vault relative humidity below 60 %, non‑condensing. Sustained high‑humidity exposure degrades fan‑motor winding insulation and lubricant properties. Extended shelf‑storage may degrade bearing grease; pre‑run bench testing is strongly recommended before field deployment.
No user‑serviceable on‑board lithium backup battery resides on this assembly. Every 18‑months inspect impeller for dust‑contamination and rear mating connector pins for oxidation or mechanical damage; deformed contacts create intermittent fan operation and unplanned rack over‑heating events.
6. Physical Installation Prerequisites
Execute lock‑out‑tag‑out procedures and de‑energize the SIMATIC‑TDC UR‑series subrack. Slide the fan‑tray unit fully into the dedicated upper fan‑slot until the rear wiring connector achieves positive latching engagement. Confirm correct bottom‑to‑top airflow direction matching original OEM specification; reversed airflow invalidates designed thermal dissipation performanceSiemensPLC.
Maintain unobstructed intake and exhaust clearances around the rack cabinet. Blocked intake / exhaust openings negate fan‑assembly cooling capacity and produce thermal‑induced drift and hardware shutdowns for CPU and I/O boards.
Torque cabinet protective‑earth connections to OEM‑specified torque value. Tie cabinet protective‑earth to facility plant ground bus, never rely solely on signal‑cable shielding. After hardware replacement, power‑on the rack and verify smooth fan‑impeller rotation, absence of abnormal vibration or acoustic noise, and monitor rack‑module temperature diagnostics via HW‑Config before returning system to live production duty. Hot‑swap insertion‑removal is not supported.
7. Buyer’s FAQ
Q: What Harmonized System tariff code applies to 6DD1682‑0CH0 for cross‑border shipments?
A: This legacy Siemens SIMATIC‑TDC rack fan assembly maps to HS 841459 for industrial cooling‑fan assemblies. Customs inspectors commonly require full part‑number plus hardware‑revision documentation. Confirm classification cooperating with your import broker before tendering freight.
Q: How does Country of Origin impact audit acceptance for this end‑of‑life cooling spare?
A: Plant audit checklists cross‑reference nameplate Country‑of‑Origin markings against site‑approved asset registers. Parallel‑sourced spares carrying mismatched COO markings trigger formal audit observations, even when bench spin‑up testing appears normal.
Q: Should supplementary shipping insurance be purchased for this obsolete TDC fan‑tray spare?
A: Yes. Transit shock can damage fan‑motor bearings, deform impeller blades or produce rear‑connector‑pin damage. Many mechanical defects may not be apparent by superficial visual inspection. Secure full‑value all‑risk coverage; standard carrier cargo terms exclude hidden mechanical damage to rotating‑component hardware.
Q: Does the delivered 6DD1682‑0CH0 ship pre‑loaded with site‑specific thermal‑monitoring configuration?
A: Factory‑sealed OEM units are purely electromechanical cooling hardware, containing no programmable firmware. Rack thermal‑monitoring thresholds reside within the SIMATIC‑TDC host‑CPU project and are not stored within this fan tray. After replacement, validate rack‑level module temperature telemetry before placing the spare hardware into live production duty.
