Programming Parameters

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: 1-9 stating the UPS parallel address in system.

2.“Highest station number”

•Valid station numbers: 2-9 stating the number of UPSs in system.

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”: Stand-by-time will be 24 hours - on-line time will be 48 hours (xN systems).

•“Yes”: Stand-by-time will be 1 min. - on-line time will be 2 min (xN systems).

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 (for charge voltage compensation).

NOTICE!

Common battery pack is a technical possibility.

However, APC recommend separate battery pack due to a higher safety degree in connection with redundant/parallel operation.

The UPS system is designed for both situations.
