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.
