Hello! The L / G terminal is needed to connect zero, this is shown in the diagram from the manufacturer. The COM terminal is used when connecting walk-through and cross-circuit breakers. L is the incoming phase from the network. L1 and L2 are the outgoing phases to the corresponding groups of luminaires. Connection schemes provided. Has everything become clear?
