•
The service logon provides direct access to a
specific security level for the duration of the
current day.
•
Obtain the service logon from Danfoss.
•
Enter the logon via the display, or the web
interface logon dialog.
•
When the service task is complete, log off at
[Setup

Security].
•
The inverter automatically logs the user off after
10 minutes of inactivity.
Security levels are similar on the display and the web
interface.
A security level grants access to all menu items at the
same level as well as all menu items of a lower security
level.
3.1.3 Preparation for Master Inverter
The master mode feature allows 1 inverter to be appointed
as master inverter for the inverter network.
The master inverter accesses the other inverters in the
network, enabling:
•
Settings and data replication to the rest of the
network, enabling easy commissioning and data
management.
•
Control of power at plant level (control of
ancillary services).
•
Data retrieval from the network, for graphical
display on the web interface, upload to a data
warehouse, or export to a PC.
Before enabling master mode, ensure that the following
requirements are met:
•
No other master inverters are present in the
network.
•
Ethernet connection from PC to inverter RJ-45
interface, using a patch cable (network cable
cat5e, crossed or straight through). See
2.7 RS-485
or Ethernet Connections
.
•
Installed sensor interface option, with sensors
installed, when sensor data are required.
•
Location closest to the router, in a daisy chain
network topology.
After enabling master mode, perform a network scan to
verify that all follower inverters are connected to the
master inverter. To initiate the scan, go to [Setup
→
Inverter details
→
Master mode
→
Network].
3.1.4 Manual PV Configuration
Set up the inverter for manual PV configuration:
•
Via the display, security level 1, at [Setup
→
Setup
details
→
PV configuration].
•
Via the web interface, security level 0, at [Inverter
level: Setup
→
Setup details
→
PV configuration].
When the inverter is set to manual PV configuration, the
autodetection is subsequently overridden.
To set the configuration manually via the display:
1.
Turn on AC to start the inverter.
2.
Obtain the installer password from the distributor.
Go to [Setup
→
Security
→
Password], and enter
the password.
3.
Press [Back]. Use the arrows to navigate to [Setup
→
Setup details
→
PV configuration].
4.
Select manual PV configuration mode, at: [Setup
→

→
PV configuration
→

Manual].
5.
Set up the PV input configuration to match the
wiring, at: [Setup
→

ration].
•
PV input 1: Individual, Parallel or Off
•
PV input 2: Individual, Parallel or Off
•
PV input 3: Individual, Parallel or Off
