Master chassis with Secondary chassis electrical
connections
Figure 47 shows how to connect an analyser that is supplied with a master
chassis and a secondary chassis. Connections to a power source must use
properly rated cables (see section 3.13).
If an auxiliary oven is supplied, connect the cable coming out of the auxiliary
oven to the chassis
connector named “Auxiliary
O
ven”
(see section 1.5.2). The
cable carries the power supply and the temperature measurement.
The master chassis communicates with the secondary chassis using RS-485
ports. Connect both RS-485 ports using the provided high density DB-9 cable
(see section 3.11 and Figure 47).
