Wiring the XMO2
Transmitter
This section describes how make all necessary electrical connections
to the XMO2 system.
CE Mark Requirements
Caution!
To meet CE Mark requirements, all electrical cables must
be grounded and shielded as described in this section.
IMPORTANT:
CE Mark compliance is required for all units used in
EEC countries.
CE Mark requirements include compliance with both the EMC and
LVD directives.For EMC compliance, the electrical connections must
be shielded and grounded as shown in Table 2-1 below. After all the
necessary electrical connections have been made, seal any unused
cable entry holes with standard conduit plugs or equivalent.
Note:
If the instructions in this section are followed, the unit will
comply with the EMC Directive 89/336/EEC.
For compliance with the European Union’s Low Voltage Directive
(73/23/EEC), the XMO2 requires an external power disconnect
device such as a switch or circuit breaker. The disconnect device must
be marked as such, clearly visible, directly accessible, and located
within 1.8 m (6 ft) of the unit.
Note:
If the instructions above are followed, the unit will comply
with the Low Voltage Directive (73/23/EEC)

Connection Wiring Modification
Power 1. When connecting the line power, select the
cable entry closest to the XMO2 chassis ground.
2. Use shielded cable* to connect the line power to
the XMO2. Terminate the shield at the internal
ground screw (see Figure 2-3 on page 2-7).
3. Connect the power ground wire to the internal
ground screw (see Figure 2-3 on page 2-7).
Input/Output 1. Use shielded cable* to interconnect the XMO2
enclosure with any external I/O devices.
2. Connect the shields to the internal ground screw
(see Figure 2-3 on page 2-7).
*Wires enclosed in a properly-grounded metal conduit do not
require additional shielding.
