B-26 External Connections
Connecting Ethernet cables
Requirement: Shielded Ethernet cables must be used 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.
I/O signal connectors
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.
Warning: To avoid electric shock, all electrical connections to the rear
panel must be separated 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 auto-samplers, 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.
