5.7 Connecting DC Input Power Cables
CA UTION
Two models of PV connectors are delivered with the device: Amphenol Helios H4
and Staubli MC4. PV connectors of
dierent models cannot be used together.
Device damage caused by mixed use of dierent PV connectors is not covered by
the warranty.
● For details about using Amphenol Helios H4 PV connectors, see section 5.7.2
Connecting Cables to Amphenol Helios H4 Connectors.
● For details about using Staubli MC4 PV connectors, see section 5.7.3
Connecting Cables to Staubli MC4 Connectors.
5.7.1 Cable Connection Description
Precautions
D ANGER
● Before connecting the DC input power cables, ensure that the DC voltage is
within the safe range (lower than 60 V DC) and that the three DC switches on
the solar inverter are set to OFF. Failing to do so may result in electric shocks.
● If you turn a DC SWITCH to ON by mistake when connecting or disconnecting
DC input power cables, do not remove or insert DC input terminals. If you need
to remove or insert a DC input terminal, perform the operations provided in 8.2
Power-O for Troubleshooting.
● When the solar inverter operates in grid-tied mode, do not perform
maintenance or operations on the DC circuit, such as connecting or
disconnecting a PV string or a PV module in the PV string. Failing to do so may
cause electric shocks or arcing, which may also cause
re.
WARNING
Ensure that the following conditions are met. Otherwise, the solar inverter may be
damaged, or even a
re could happen.
● According to IEC 62548, the maximum open-circuit voltage of each PV string
cannot exceed 1100 V DC at the lowest average annual dry-bulb temperature.
● The polarities of electric connections are correct on the DC input side. The
positive and negative terminals of a PV module connect to corresponding
positive and negative DC input terminals of the solar inverter.
