Ensure that AC terminations provide firm and solid electrical connections. Failing to do so
may cause SUN2000 malfunction and damage to its terminal block, even starting thermal
events. Any SUN2000 damaged due to weak termination will result in revocation of
product warranty.
When connecting a PE cable, secure the screws using a socket wrench with an extension
wrench longer than 200 mm.
If the AC output power cables are subject to a pulling force because the inverter is not
installed stably, ensure that the last cable that bears the stress is the PE cable.
