Procedure
Step 1 Prepare DC power cables and route them into the maintenance compartment
through the cable holes at the bottom of the SUN2000.
Use the DC terminals provided with the SUN2000. Using other terminals may
result in serious consequences. The caused device damage is not covered under
any warranty.
● Keep the DC input PV+ cable and PV– cable close to each other.
● Cables with high rigidity, such as armored cables, are not recommended as DC
input power cables, because poor contact may be caused by the bending of the
cables.
● After crimping the DC wiring terminals, pull the DC input power cables back to
ensure that they are connected securely.
