Installing Cables
1. Before installing cables, ensure that all required OT terminals and cables are prepared.
2. The following table lists only recommended cable specifications. For more cable
specifications, see the user manual.
• Do not connect loads between the inverter and the AC switch that directly connects to the
inverter. Otherwise, the switch may trip by mistake.
• If an AC switch is used with specifications beyond local standards, regulations, or the
Company's recommendations, the switch may fail to turn off 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 output switch.
To ensure that the inverter can be safely disconnected from the power grid when an exception
occurs, connect an AC switch to the AC side of the inverter. Select an appropriate AC switch in
accordance with local industry standards and regulations.
