How to remove the converter fans in frames D1 to D3 (two fans)
Converters types DCS800-S01-0045-0x to DCS800-S02-0350-0x using two 115
VAC fans. Depending on the supply voltage they are either connected in series, for
230 VAC. or in parallel, for 115 VAC:
Fan configuration D1 to D3
In case a fan fails there are different approaches due to the incoming voltage.
230 VAC:
With a supply voltage of 230 VAC fans M55 and M56 are connected in series.
Consequently both fans have to be of the same manufacturer and type. Thus it is
not possible to change only the broken fan. In this case both fans have to be
changed.
115 VAC:
With a supply voltage of 115 VAC all fans are connected in parallel. Thus it is
possible to change only the broken fan.
