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.

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.
