Waters ACQUITY UPLC I-Class, System Manual, Page: 61 / 68

Signal connections B-5
Ethernet connections
The sample manager incorporates an internal 10/100/1000 megabit Ethernet
switch that accommodates the PC (workstation) and as many as six ACQUITY
UPLC I-Class modules. Connect the shielded Ethernet cables from each
module to the electronic connections on the rear panel of the sample manager.
The sample manager is connected internally to the Ethernet switch.
Tip:
Use a Waters switch box if you are running multiple stacks of modules.
Column heater connection
The sample manager powers and communicates with the column heater. The
external communication cable must be connected to the rear of the column
heater and the sample manager.
To make column heater connections:
1. Make sure the sample manager and the column heater are powered-off.
2. Connect the external communication cable to the High Density (HD)
port on the rear of the column heater.
3. Connect the other end of the external communication cable to the QSPI
port on the rear of the sample manager.
Signal connections
Making signal connections
Refer to the signal connection location shown on the silk-screened label affixed
to the rear panel of each system module.
Caution:
To avoid damaging electrical parts, never disconnect an
electrical assembly while power is applied to a system module. To
interrupt power to a module, set the power switch to Off, and then
unplug the power cord from the AC outlet. After power is removed,
wait 10 seconds thereafter before you disconnect an assembly.
