I have a R5500 UPS with an ERM module, connected to a server running the HP UPS Management Module software.
The software has started reporting a "critical alarm" saying "Loss of redundant communication".
What does this mean?
Could it be that the ERM module is not correctly installed?

When I did a search on this problem all I found was your post of a year or so ago.
Here is the answer:
Make sure you specify the first UPS's IP, and the second UPS on all your servers' Agent software is set to No Server (Management Sever 1 and 2) otherwise you get this error all the time . This setting is for redundant UPS setup.
On the UPS look for servers with RU error - this means they are communicating with more than one UPS...
RU—The agent is communicating with both UPSs and
both UPSs have normal status.
AS—The agent is communicating with the management
