5.5 Installing the AC Output Power Cable
Precautions
An AC switch must be installed on the AC side of the SUN2000 to ensure that the
SUN2000 can be safely disconnected from the power grid.
● Do not connect loads between an inverter and an AC switch that directly
connects to the inverter. Otherwise, the switch may trip by mistake.
● If an AC switch is used with
specications beyond local standards, regulations,
or the Company's recommendations, the switch may fail to turn
o in a timely
manner in case of exceptions, causing serious faults.
Each inverter must be equipped with an AC output switch. Multiple inverters
cannot connect to the same AC switch.
● Ensure that the AC terminals are securely connected.
● Keep the AC output power cable and the PE cable close to each other.
● Ensure that AC output cable is secured. Failing to do so may cause SUN2000
malfunction or damage to its AC connector.
● Ensure that the cable is not twisted.
Procedure
Step 1 Prepare AC cord end terminals and route them into the maintenance
compartment through the cable hole at the bottom of the SUN2000.
