ELECTRICAL
INSTALLATION
All wiring must conform to local and national codes. Multiple wiring diagrams
are shown in this section. Always refer to the diagrams that apply to your
transmitter configuration and disregard all other wiring diagrams.
Xi Advanced Electronics
NOTE
Line voltage, signal, and relay wiring must be rated for at least 105
°C
(221°F).
NOTE
If metal conduit is used with the Xi the conduit should be reliably bonded to
protective earth. The grounding plate inside the Xi is not bonded to PE and
does not provide adequate grounding.
1. Remove cover screws from the front cover of the Xi. Swing down the
front cover of the interface box.
2. Pull out the I/O board on the right-hand side of the card rack inside the
Xi. If your system is configured to operate two transmitter probes there
are two I/O interface boards.
3. See Figure 2-4. Connect the 4-20 mA signal wires at J4 of the I/O
board. Attach the supplied ferrite clamp over the 4-20 mA OUT wires
that extend past the shield.
NOTE
Installation of the ferrite clamp over the 4-20 mA OUT wires is required for
compliance with the European EMC Directive.
Disconnect and lock out power before connecting the power supply.
Install all protective covers and safety ground leads after installation. Failure to install covers
and ground leads could result in serious injury or death.
To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation
of this equipment, connection to the main electrical power supply must be made through a
circuit breaker (min 10A) which will disconnect all current-carrying conductors during a fault
situation. This circuit breaker should also include a mechanically operated isolating switch.
If not, then another external means of disconnecting the supply from the equipment should
be located close by. Circuit breakers or switches must comply with a recognized standard
such as IEC 947.
