at all times.
¾
To earth the device:
1.
Connect an electrically earthed strap of 16 AWG wire (minimum) to the chassis' earthing

To connect the device to the IP/Ethernet network:
1.
On the CPU module, connect the first Ethernet port (labeled
I
) directly to the Ethernet
network, using a straight-through RJ-45 Ethernet cable.
2.
Optionally, for Ethernet redundancy, connect the second Ethernet port (labeled
II
) to the
Ethernet network.
