CE Installation Requirements

If the bridge is being installed at a site that must meet CE requirements, the

following steps must be taken to complete the installation.

Grounding

The bridge must be provided with a direct ground connection of 0.1 ohm or less.

Mounting the bridge on a suitably grounded panel as described in Section 2.4

satisfies this requirement.

In addition the Modbus Plus cable must be grounded to the panel using the ground

wire that is integral to the cable.

Ferrite Bead on RF--45 Cable

If the Ethernet network is being connected to the 10Base--T (RJ--45) connector, an

approved ferrite bead must be installed on the cable at the connector.

The approved bead shown in Figure 9 and in Table 10 is enclosed in a plastic box

which can be clipped over the network cable. It is not necessary to insert the

cable through the bead before you install the RJ--45 connector on the cable.
