If one switchboard cabinet is insufficient for the compensation, several systems can be
combined with each other. The power supplies for the switchboard cabinets must be
connected in parallel. As indicated in section 5.2, the CT interfaces must be connected to
each other in series!
NOTE
• The power supplies for the switchboard cabinets must be connected in parallel.
• The CT interfaces must be connected to each other in series! (as in section 5.2)
Set the following parameters in the “System Settings” menu (see Figure 4-31):
• “Slave Module Quantity”
must be set to the number of modules to be monitored by
the 7-inch monitor.
• Set “Total Capacity”
to the sum of the capacities of all modules.
Parameters that are required to start the modules without a display:
1. Operating mode (see section 8.1.3)
2. Power On mode
3. CT position (load or grid side)
4. Slave Module Quantity
(Individual module mode = 1; for several modules = number of modules);
5. Total capacity
6. Compensation mode (intelligent mode, sequential mode or “All” mode)
7. CT ratio
8. Compensation rate
Note:
The external 7-inch monitor is used to monitor the modules without a display.
In a manner similar to that for the integrated 4.3-inch LCD monitor, 12 operating modes can
be configured on the 7-inch monitor under “
Settings
” (see 8.1.3 Parameter settings).
