5 Transportation, storage and check of delivery Transportation Always transport the RHE46 Coriolis transmitter in its original packaging. Storage Store the RHE46 Coriolis transmitter under the following conditions until it is installed: ■ In the original packaging ■ Dust-free, dry and not exposed to direct sunlight ■...
Mounting on the DIN rail Open the DIN rail lock at the bottom (1). Place the RHE46 on top of the DIN rail (2) and press it down (2). Close the DIN rail lock (4) to fix the RHE46 on the DIN rail.
Wire the RHE Coriolis transmitter to the RHM Coriolis sensor according to the corresponding wiring diagram (QR code on the side of the RHE46), e.g.: Make sure that you connect the associated RHM to the RHE. See type plate of the RHE for the serial number of the associated RHM at "Set for".
Connecting the power supply The RHE46 Coriolis transmitter requires a regulated DC power supply of 12 to 24V ±10%. The power consumption is max. 4W. Fuse (suitable for the cable being used, max. 10 A) +24 V connection Ground connection Connection for protective conductor 1.
For the wiring of the Modbus TCP / EtherNet/IP / Profinet interface, please refer to the wiring diagram (QR code on the side of the RHE46). Once the RHE46 Coriolis transmitter has been connected, it is assigned an IP address, which is required in order to connect the RHE46 Coriolis transmitter with your own network.
