3.
Lead the cable through cable gland, and insert into the insulator until it
snaps into place. Then tighten the cable gland (torque 2.5 N
m to 3 N
m).
4.
Make sure that the cable polarities of the PV string are correct.
The inverter will not function properly if the DC polarities are reversed.
5.5.3 Installing the PV Connector
There is a risk of inverter damage! The following requirements should be met,
otherwise they will lead to loss of any and all warranty rights.
y
Make sure that the maximum short circuit current of each DC input is less
than inverter allowable limit.
y
Make sure that the maximum open voltage of each string is less than 600V.
Voltage over 600 V can damage the inverter.
Connect the inverter to PV array according to the following procedure.
1.
(
Optional
) If you purchase the DC switch, rotate it to “OFF”.
2.
Check the connection cable of the PV string for the correct polarity and that
the open-circuit voltage does not exceed the inverter input limit of 600 V,
even under the lowest operating temperature. Refer to the module
specification supplied by the module manufacturer for detailed information.
