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.
I/O signal connectors:
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.
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.
