Legend to connection example
RCMS… Residual current monitors
AN420 When AC/DC sensitive W…AB series measuring current
transformers are used, an AN420 or AN110 power supply
unit is required that supplies up to six measuring current
transformers of this type. When the supply voltage of
AN110-1 is < 30 V, the output power decreases, so that only
five measuring current transformers can be connected.
COM460IP Protocol converter for connecting the BMS bus (Bender
measuring device interface) with a TCP/IP (Transmission
Control Protocol/Internet Protocol) network via Ethernet.
