• Ensure that the AC output power cable is connected securely. Otherwise, the SUN2000 may fail 
to operate or experience a fault that will damage the terminal block. For example, the SUN2000 
may generate heat during operation due to unreliable connection.
• If the SUN2000 is insecurely installed and the AC output power cable bears the pulling force, 
ensure that the last cable bearing the force is the PE cable.
