5.7
Individual module stop/start procedure (redundant parallel system)
As described earlier in this manual, if a parallel module UPS system includes module redundancy an individual UPS
module can be shut down without affecting the overall system operation. The situations where this might be put into effect
are usually managed by a qualified service engineer when undertaking service repairs; however, under certain
circumstances there may be a case for this to be carried out by the user. For example, if a large proportion of the load is to
be shut down for a significant period the number of on-line modules in the UPS system might be reduced to save on the
utility power demands.
WARNING:
The load will be transferred to bypass and not supported by the UPS system if:
• You turn off the module in a standalone system, or
• You turn off a module in a capacity rated system (which may overload the remaining on-line modules).
