During DC input power cabling, leave at least 50 mm of slack. The axial tension
on PV connectors must not exceed 80 N. Radial stress or torque must not be
generated on PV connectors.

Removing DC Connectors
Before removing the positive and negative connectors, ensure that DC SWITCH is
set to OFF and that the current is less than 0.5 A.
To remove the positive and negative connectors from the inverter, insert an open-
end wrench into the bayonet and press the wrench with force. Then remove the
DC connectors with caution.
