Installing DC Input Power Cables
Use dedicated insulated tools to connect cables. Ensure that battery cables are connected to
correct polarities. If the battery cables are reversely connected, the battery may be damaged.
1. You are advised to connect the battery terminals (BAT+ and BAT–) on the switch side to the
inverter and connect the other side to the cascaded battery.
2. The battery terminals use the Staubli MC4 positive and negative metal terminals and DC
connectors supplied with the solar inverter. Using incompatible positive and negative metal
terminals and DC connectors may result in serious consequences. The caused device damage is
not covered under warranty.
