3.4.3
Connect DC voltage
DANGER
Risk of death due to high DC voltage! As soon as the sun shines, volt-
age is applied to the PV modules.
f Before connecting the inverter, check whether voltage is applied to
the generator's DC voltage connection.
f Before connecting the inverter, check whether the polarity of the DC
voltage is correct.
f If voltage is applied, wear insulating protective clothing and face
protection.
f Ensure that the cable plug has engaged completely with the socket.
f Detach the DC voltage cable only if the inverter is not in operation.
f Make sure that the DC isolator or a central isolation device can be
accessed freely.
f Do not earth PV modules. The inverter does not have a transformer.
CAUTION
Damage to property!
f Use only the original DC voltage Multi-Contact MC4 cable plug.
f Only connect PV modules that meet the requirements of IEC 61730
class A.
f Ensure that the max. DC voltage permitted is not exceeded.
f Ensure that the max. direct current permitted per string is not ex-
ceeded.
f If national provisions require an external disconnect device, one
disconnect must be installed for TA and one for TB.
Connection C is not used.
