Either type A (W…, WR…, WS…, WF… series) or type B (W…AB series) measuring current transformers can be selec- ted for each measuring channel. When using up to six type B measuring current transformers, an AN420-2 or AN110 power supply unit is required (for connections see page 29). The channels k9…k12 of the device versions RCMS490-D4/- L4 require the connection of type A measuring current trans- formers.A, BBMS bus (RS-485 interface with BMS protocol)R, T/R
