Connect the back wires of the eight PT sensors via a potential distribution terminal (KL9187). The KL9187
leads the back wires via Power Contact (0 V) back to the KL3228.
Mount the KL3228/KL9187 directly before the KL9010 bus end terminal
Mount the KL3228/KL9187 directly adjacent to each other and as far to the right as possible in the
Bus Terminal block, ideally directly before the KL9010 bus end terminal!
If further Bus Terminals that draw current from the power contacts are mounted to the right of the
KL3228/KL9187 in the Bus Terminal block, this current will lead to a voltage drop on the power con-
tacts between KL3228 and KL9187. This voltage drop can falsify the measured values of the
KL3228, since the back wires of the PT sensors are also routed via the power contact (0 V).
