1. Safety and Conformity
1.1. Important Safety Information
All persons installing and servicing inverters must be:
• Trained and experienced in general safety rules for work on electrical equipment
• Familiar with local requirements, rules and regulations for the installation
Safety information important for human safety. Violation of warnings may result in
injury to persons or death.
Information important for the protection of property. Violation of this type of in-
formation may cause damage and loss of property.
Note:
Useful additional information or “Tips and Tricks” on specific subjects.
Read this before installing, operating or maintaining the inverter.
1. Safety and Conformity

Before installation:
Check for damage to inverter and packaging. If in doubt, contact the supplier be-
fore installing the inverter.
Installation:
For optimum safety, follow the steps described in this manual. Keep in mind that
the inverter has two voltage carrying sides; the PV input and the AC grid.
Disconnecting the inverter:
Before starting work on the inverter, switch off AC grid at the mains switch and PV
using the PV load switch. Ensure that the device cannot be unintentionally recon-
nected. Use a voltage tester to ensure that the unit is disconnected and voltage
free. The inverter can still be charged with very high voltage at hazardous levels
even when it is disconnected from grid/mains and solar modules. Wait at least 30
min. following disconnection from grid and PV panels before proceeding.
Maintenance and modification:
Only authorised personnel are allowed to repair or modify the inverter. To ensure
optimum personal safety, only original spare parts available from the supplier
should be used. If non-original spare parts are used, the compliance with CE
guidelines in respect of electrical safety, EMC and machine safety is not guaran-
teed.
Also observe the danger of burn injury. The temperature of the cooling racks and
components inside the inverter may exceed 70ºC.
Functional safety parameters:
Never change the parameters of the inverter without authorisation from the local
energy supply company and instructions from Danfoss.
Unauthorised changes of functional safety parameters may cause injury or acci-
dents to people or inverter. Additionally it will lead to the cancellation of all inver-
ter operating approval certificates.
The Danfoss inverters are all designed according to the German VDE0126-1-1
(February 2006) standard, which includes an insulation test between PV array(s)
and Earth, and a type B, RCMU according to DIN VDE 0100-712.
1.2. Hazards of PV Systems
Very high DC voltages are present in the system even when the AC grid is disconnected. Faults
or inappropriate use may lead to electric arcing. Do not work on the inverter while it has cur-
rent connected to it.
The short-circuit current of the photovoltaic panels is only slightly higher than the maximum op-
erating current and depends on the level of solar irradiation.
1.3. PV Load Switch
Illustration 1.1: TripleLynx CN PV Load Switch
The inverter has been equipped with a PV
load switch (1) for safe disconnection of DC
current.

2.1.1. Installation Sequence
1. Read the installation manual. Pay special attention to the section Important Safety In-
formation .
2. Install the inverter according to the section
Installation Dimensions and Patterns and
the section Mounting the Inverter .
3. Open the inverter according to the section Opening and Closing the Inverter .
4. Install AC according to the section AC Grid Connection .
5. Install PV. Remember to use the terminal block to establish parallel connection (if re-
quired), as described in the section PV Connection . The inverter has auto-detection.
6. Install Auxiliary input according to the section Connection of Peripheral Units .
7. Close the inverter according to the section Opening and Closing the Inverter .
8. Turn on AC at the mains switch.
9. Set language, time, date, installed PV power and country:
-For setup via the integrated Web Server, see the TripleLynx CN User Manual,
Web Server Quick Guide section
-For setup via the display, see the section Start-up and Check of Settings in
this manual.
10. Turn on PV by turning the PV load switch on.
11. Verify the installation by comparing with the auto-detection result in the display, as de-
scribed in the section PV Connection .
12. The inverter is now ready for operation.
