Danfoss TripleLynx User Manual

When unmated the MC4 connectors are not IP54. The intrusion of moisture may
occur in the following situations:
1. The inverter runs in Master/Slave operation and only one or two PV in-
puts are in use. In this case, the other inputs are not connected to PV
and they are therefore open to intrusion.
2. Not all PV inputs are connected.
3. PV connectors are not fitted; for example in case of disconnection of
parts of a PV plant over a longer period of time.
In situations where the PV connectors are not fitted, a seal cap must be mounted
(included in the scope of the delivery). All inverters with MC4 connections are de-
livered with seal caps on inputs 2 and 3. During installation, the seal caps of those
inputs that are to be used are discarded.
Note:
The inverter is protected against reversed polarity but it will not generate power until the po-
larity is corrected. To achieve optimum production, the open circuit voltage (STC) of the PV
modules must be lower than the max. input voltage of the inverter (see the specifications),
multiplied with a factor of 1.13. U

Auxiliary Input/Output
Note:
When choosing the installation place, ensure that all labels are visible at all times.
For details refer to the section Specifications .
The inverter has the following auxiliary input/output:
• 2 x RJ45 for RS485
• 2 x RJ45 for Ethernet
• 1 x 8 pole terminal block for RS485
• 1 x 10 pole terminal block for
- PT1000 temperature sensor input x 3
- Irradiation sensor input
- Energy meter (S0) input
• 1 x 2 pole terminal block for relay outputs
Refer to the specifications for an overview of the communication board and to the inverter user
manual for details regarding auxiliary input configuration via the display.

Autotest Procedure - Italy Only
An automatic test of the inverter can be initialised by activating the Inverter Autotest Software
in the display. On the display find [Setup → Setup details → Autotest] and press OK.
The autotest of the inverter will now start.
To initiate autotest via the integrated web interface, navigate to [Inverter → Setup → Setup de-
tails → Autotest] and click on [Start → Test].
The inverter autotest manual can be obtained from the inverter manufacturer.
