6.1.4 Stand-alone PC with Secondary chassis electrical connections
Figure 49 shows how to connect an analyser supplied as a stand-alone PC with a
secondary chassis. Connections must be connected to a power source using
properly rated cables (see section 3.12). The stand-alone PC must always be
connected to the same protective earth as the secondary chassis of the system.
If an auxiliary oven is supplied, connect the cable coming out of the auxiliary
oven to the connector named
“Auxiliary
O
ven”
on the stand-alone PC. The cable
carries the power supply and the temperature measurement.
The stand-alone PC communicates with the secondary chassis using a RS-232
port. Connect the
port “To analyser” on the PC to the
RS-232 port on the
secondary chassis (see Figure 49).
