Installation
Connecting to Ethernet Network
1. Unscrew the 4 screws of the housing cover (see Figure 3.6 on page 23).
2. Remove the housing cover.
3. Route the Ethernet cable through the cable gland in the middle of the Gateway housing.
The permissible cable diameter lies between 6 ... 10 mm.
4. Connect the Ethernet cable to the terminal block labelled "Ethernet" (see Figure 3.9 on
page 26) according to the following figure/tables.
5. Screw the housing cover to the housing again.
6. Tighten the cable gland with appropriate torque (see table "Installation torque cable
glands" on page 32).
The Gateway is now connected to the Ethernet network. The yellow Ethernet
communication status LED starts flashing when a correct HART or Modbus protocol
message is received (see chapter 6.1).
