3.6 Connections to electronic boards
Note: Any loose connection wires should be bundled tightly together with the use of nylon cable ties.
3.6.1 Sensor cable
An ORBISPHERE cable (10 wire shielded, Part N° 32505.mm) is needed to connect the
sensor(s) to the instrument. The instruments have a Lemo 10 socket on the back panel where
the sensor cable has to be connected.
3.6.2 Electronic boards connectors
Connectors P8 on the main board, and connectors J7 and J8 on the measurement board(s) are
made of two parts. Push down carefully the black levers on either side of the connector and pull
it out securely. Perform all connections with these connectors unplugged. Once finished, attach
the connectors to the boards by pushing them firmly in place (levers up).
3.6.3 Main board connections
NOTICE
Potential Instrument Damage. Delicate internal electronic components can be
damaged by static electricity, resulting in degraded performance or eventual failure.

Connector P3
Ethernet RJ 45. Connect the wall and panel mount instruments to the local network by passing
an ethernet cable through the ethernet cable gland (refer to Figure 6 on page 24 for the wall
mount and Figure 10 on page 27 for the panel mount). Connect to the P3 connector illustrated
above.
