B.9
Connecting Ethernet cables
Requirement:
Use shielded Ethernet cables with the instrument to ensure compliance with FCC,
and other, limits.
To make Ethernet connections:
1.
Connect one end of one shielded Ethernet cable to the network switch, and then connect
the other end to the Ethernet card on the preconfigured ACQUITY workstation.
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 back of the instrument, and
then connect the other end to the network switch.
B.10 I/O signal connectors
Warning:
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.
To avoid electric shock and damage to the instrument, do not apply more than
•
±30 V d.c. to the Analog (Out) connection.
•
30 V d.c. 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 two removable connectors 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.

To avoid electric shock, separate all electrical connections to the rear panel from
I/O signal connectors
