Fronius Primo 10.0-1 208-240 Instructions D'installation page 5

CAUTION! Overloading the inverter may damage it.
- Observe the maximum current carrying capacity of different power categories (see Table A).
- Only connect a maximum of 33 A to each DC terminal.
- Connect the DC+ and DC- cables to the correct DC+ and DC- terminals on the inverter.
- Observe the maximum DC input voltage.
Table A
Power category
10.0-1 208-240 / 11.4-1 208-240 / 12.5-1 208-240 / 15.0-1 208-240
CAUTION! Danger of short circuit from loose metal parts from knockouts. Loose metal parts in the in-
verter may cause short circuits when the inverter is powered up. When removing knockouts, make sure
that
- no loose metal parts fall into the inverter,
- any metal pieces that do fall into the inverter are removed immediately.
NOTE! Degree of protection NEMA4X is only ensured when the inverter is mounted and firmly screwed
into the wall bracket.
The wall bracket without inverter has no NEMA protection
NOTE! Photovoltaic modules exposed to light supply current to the inverter.
NOTE! When using the cable inlets at the back, take care to seal them according to degree of protec-
tion NEMA4X before operating outdoors.
NOTE! When installing outdoors, only use waterproof conduit fittings and conduits. Conduit fittings and
conduits are not part of the scope of supply for the inverter.
NOTE! When connecting aluminum cables:
- follow all national and international guidelines regarding the connection of aluminum cables,
- follow the instructions of the cable manufacturer,
- perform an annual check to ensure that the cables are firmly attached according to the proper tor-
que.
NOTE! When connecting DC cables, ensure the polarity is correct.
NOTE! Form a wire loop according to NEC using all wires.
NOTE! Follow general ESD guidelines when handling option cards.
NOTE! Fronius will not bear any costs for loss of production, or installations, etc., which may arise due
to a detected electric arc and its consequences. Fronius accepts no liability for fires which may break
out despite integrated arc detection/interruption (e.g., due to a parallel arc).
NOTE! Before an inverter can be reset following a detected electric arc, check the entire affected pho-
tovoltaic system for any damage.
