Tip:
On preconfigured systems, the Ethernet card is identified as the Instrument LAN card.
2.
Connect one end of the other shielded Ethernet cable to the Ethernet port in the top, right-
hand corner of the mass spectrometer’s rear panel, and then connect the free end to the
ACQUITY instrument’s network switch.

Warning:
To avoid electric shock, separate all electrical connections to the rear panel
from hazardous voltages by double or reinforced insulation. Circuits of this type are
classified as safety extra low voltage (SELV). Examples of circuits that are typically
SELV include contact closure inputs and outputs for autosamplers, and UV, RI, and
fluorescence detector signal outputs for LC/MS systems. The electrical connections on
the rear panel of this mass spectrometer are all SELV.
Notice:
To avoid damage to the instrument, do not exceed these voltages:
• ±30 Vdc to the Analog (Out) connection.
• 30 Vdc to the Stop Flow (Out), Inject Start (In), Switch 2 (Out), Switch 3 (Out), and
Switch 4 (Out) connections.
The instrument’s rear panel includes a removable connector that hold the screw terminals for I/O
signals. These connectors are keyed so that they can receive a signal cable inserted only one
way.
