8. Speed Control Splitter to use
Verify you have a compatible Speed Control Splitter to prevent device failures.
Problem:
The Speed Control Splitter connecting multiple Retrotec fans together may cause failure of all connected Fan
Tops, Drives, or any other devices via Control (Ethernet) Cable.
Product Affected:
Any device connected to a Speed Control Splitter via Control (Ethernet-style) Cable.
Cause:
A grounding issue with defective Speed Control Splitters that were manufactured with eight wires between the
Ethernet connectors (inside the Speed Control Splitter box)
Solution:
The FN280 Speed Control Splitter has red connectors, and does not have a problem. If you have any other
Retrotec splitter, it must be opened to examine the wiring inside. If there are eight wires between each
Ethernet connector, DO NOT USE this Speed Control Splitter. If there are four wires, you can continue to use the
Speed Control Splitter.
Use the following chart to determine if your speed control splitter is okay to use or whether you should contact
Retrotec or your reseller for a replacement.
