DANGER
n
Before you start the installation work, make sure that all the provided DC and AC
feed lines to the inverter are de-energised. The installation work must be per-
formed by a qualified electrician who adheres to the recognised rules of electrical
installations and personal health and safety regulations.
n
All the feed lines to the inverter must be appropriate for the expected voltages,
currents, and ambient conditions (temperature, UV load, etc.).
n
Make sure that all lines are laid tension-free.
CAUTION
n
The inverter must be installed in a suitable location (see “Siting” section).
n
Make sure that all the lines into the inverter are laid so as to avoid earth leakage or
short circuits.
4.6.1 Integrated overvoltage protection
The MT series inverters have integrated surge arresters (varistors) on both the DC and
AC ends.
n
On the DC end, each MPP tracker has a surge arrester from the plus and minus pole to
the earth. The surge arresters comply with requirement class C as defined in VDE
0675-6 or type 2 as defined in EN 61643-11.
n
On the AC end, each grid phase (L1/L2/L3) has a surge arrester to the earth. The surge
arresters comply with requirement class D as defined in VDE 0675-6 or type 3 as de-
fined in EN 61643-11.
