3.3 Connecting to the network
The network can be connected (depending on the device) via RJ45 ports using twisted pair
cables (IEEE 802.3i/u/ab).
3.3.1 Using RJ45 Ethernet connectors
Connecting RJ45 Ethernet connectors
• Observe the correct connector coding (see also Table 3 - 2 ).
• Only use twisted pair cables with an impedance of 100

and a length of maximum
100 m (per segment).
• Only use shielded twisted pair cables and corresponding shielded RJ45 connectors. In -
sert the Ethernet cable with the RJ45 connector into a port of the twisted pair interface
(network interface 1 or 2), until the connector engages with a click.
NOTE: Connect the network connections (Ethernet) of the device to LAN installations on -
ly. Some telecommunications connections also use RJ45 connections; these must not be
connected to the RJ45 connections of the device.
For operation with 1000 Mbps (Gigabit), the following applies: Cables with four twisted
pairs (eight wires) that meet the requirements of CAT5e as a minimum must be used.
