WARNING
Before starting any work on the fans, de-energize the cooling unit.
The roof-mounted cooling unit as used with IP54 cabinets consists of an air-to-
water heat exchanger and four fans. One fan is redundant and takes over when one
of the other fans fails.
If one fan fails, the red indicator lights up and replacement is required.
