For the KL1804 and KL1814 Bus Terminals, the reference ground for all inputs is the 0 V power contact. The versions have input filters with different speeds. The wires can be connected without tools in the case of solid wires using a direct plug-in technique.
The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
