Configuration

6.1 Reduction of the power output

Proceed as follows in order to limit the power output of the inverter::
1. Enter the customer password "72555".
2. Using the F1 key, select the menu item Configurations and confirm with the key.
3. Select the sub-menu "PAC reduction" and confirm with the key.
4. Enter the inverter power output desired and confirm with the key. An input of 70, for example,
means that the inverter will only deliver 70 % of its possible power output.
5. Switch off inverters with DC circuit breakers for 30-60 seconds.
6. The amended input value will be adopted when the device is switched back on again
Input of cos φ
The specification of cos φ can be entered in the following ways:
Using the F1 key, select the menu item Configuration and confirm with the key.
From the Configuration menu, select the sub-menu "Expanded" and confirm with the key.
Within the menu item "Expanded", select the sub-item "Numerical list" and confirm with the key.
Enter parameter "1164" using the arrow keys and confirm with the key.
The list of input options for cos φ will be displayed.
Parameter 1166: Input of the fixed value for cos φ as angle.
Parameter 1168: Squint angle via P characteristic curve by means of 10 values in degree spec-
ification. Parameters 1168.00 to 1168.10.
Parameter 1169: Squint angle via U characteristic curve by means of 10 values in degree specifi-
cation parameters 1169.00 to 1169.10

6.2 Communication via Ethernet

USS address:
Is factory-set and cannot be changed.
Protocol:
Input 0 or 1
0 = RTP protocol
1 = USS and RTP protocol
Protocol port:
Input 1024....65535; default setting 21062.
The port number is required for communication via Ethernet.

6.3 Communication via RS485

USS – adress:
Input 1 – 31
