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. For battery terminals, use the delivered Staubli MC4 positive and negative metal terminals and
DC connectors. Using incompatible positive and negative metal terminals and DC connectors
may burn the cables or damage the module. The resulting device damage will not be covered
under warranty.
