5.3Programming Parameters for Advanced Parallel Operation.
To use the advanced parallel functions the following parameters must be programmed:
1.“Station number”
2.“Highest station address”
3.“Advanced power management”
4.“APM test mode active”
5.“Battery connection”
5.3.1 Description of Settings.
1.“Station number”
•Valid station numbers:
2.“Highest station number”
•Valid station numbers:
3.“Advanced power management”
•“Disabled”: Advanced Power Management is inactive.
•“PARALLEL+1”: Advanced Power Management is activated when the system operates as PARALLEL N+1, meaning that one system can be isolated without overloading the remaining systems (N systems/UPSs).
•“REDUNDANT+1”: Advanced power management is activated when the system operates as REDUNDANT N+1, meaning that one system can be isolated without overloading the remaining systems (N systems/UPSs) with one spare system.
4.“APM test mode active”
•“No”:
•“Yes”:
5.“Battery connection”
•“Separate”: Separate battery for this UPS.
•“Common”: Common battery in a parallel system.
NOTICE!
“Common”: Common battery in a parallel system. When this setting is chosen, the highest battery temperature that can be found in the parallelled systems is used (for charge voltage compensation).
NOTICE!
Common battery pack is a technical possibility.
However, APC recommends separate battery pack due to a higher safety degree in connection with redundant/parallel operation.
The UPS system is designed for both situations.
5.3.2 Programming Example
Example with four systems in parallel with separate batteries.
•Program the station addresses
•All UPS systems have to be programmed to “Highest station address” :4.
