2.1.2 Cabling
2.1.2.1 Connecting to Earth (Ground)
The device must be permanently connected to earth (ground), using an equipment-earthing
conductor.
Protective Earthing
The equipment is classified as Class I EN60950 and UL60950 and must be earthed
at all times.
¾ To earth the device:
1. Connect an electrically earthed strap of 16 AWG wire (minimum) to the chassis' earthing
screw (located on the rear panel), using the supplied washer.
2. Connect the other end of the strap to a protective earthing. This should be in accordance
with the regulations enforced in the country of installation.

2.1.2.2 Connecting to Network
The connection to the network depends on the module housed in the device’s chassis:
CMX (refer to Section 2.1.2.2.1)
CRMX (refe
r to Section 2.1.2.2.2)
2.1.2.2.1 CMX Module
The device's CPU module provides two 10/100Base-TX RJ-45 ports for connectivity to the
Ethernet network (IP network). The dual ports provide Ethernet redundancy.
Figure 2-9: CMX Module
¾ 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.
