Programming Parameters

5.3 Programming 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.
