Input/output signal connectors B-15
Input/output signal connectors
Two removable connectors (designated External Connections 1 and External
Connections 2) are on the mass spectrometer’s rear panel; these connectors
hold the screw terminals for input/output signals. The 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 mass spectrometer signal outputs for LC/MS
systems. The electrical connections on the rear panel of this mass
spectrometer are all SELV.
Caution:
To avoid damaging the instrument,
• never apply a voltage to the Analog (out) connectors; these are active
connections driven by the instrument.
• do not apply voltages higher than those shown in the tables on
page B-17 .
