Connecting The Pv Cable To The Inverter; Safety - Fronius Tauro 50-3 Operating Instructions Manual

Connecting the PV cable to the inverter

Safety

Danger due to grid voltage and DC voltage from solar modules that are exposed
to light.
An electric shock can be fatal.
▶
▶
Danger of electric shock due to incorrectly connected terminals / PV plug con-
nectors.
An electric shock can be fatal.
▶
Danger from DC voltage. Even when the DC disconnectors are switched off, the
fuse boards (100-3-D / 99-3-D) / fuse board (50-3-D) and everything before the
DC disconnectors are live.
An electric shock can be fatal.
▶
Risk of damage to the inverter as the result of incorrectly tightened terminals.
Incorrectly tightened terminals can cause heat damage to the inverter that may
result in a fire.
▶
Risk of damage to the inverter as the result of incompatible plug connectors.
Incompatible plug connectors can cause heat damage to the inverter that may
result in a fire.

WARNING!
Prior to any connection work, disconnect the inverter on the AC side and the
DC side.
Only an authorised electrical engineer is permitted to connect this equip-
ment to the public grid.
WARNING!
When connecting version D ("direct string"), ensure that every pole of a
string is fed across the same PV input, e.g.:
'+ pole string 1' at input PV 1.1+ and '- pole string 1' at input PV 1.1-
WARNING!
Prior to any connection work, disconnect the inverter on the AC side and the
DC side.
CAUTION!
When connecting AC and DC cables, ensure that all the terminals are
tightened to the specified torque.
CAUTION!
Only use the original plug connectors (MC4) manufactured by Stäubli
(formerly Multi-Contact).
