2.3.4 Computer and monitor
The computer and monitor can be connected to any appropriate AC outlet as
long as you make sure the voltage selection switch on the back of the computer
correctly matches the voltage at the outlet (table 2-3). See table 2-2 for plug
and receptacle configurations.
2.4 Requirements for nitrogen cylinders and
pressure regulators
You can use a centralized nitrogen source or provide a separate nitrogen
cylinder for each instrument. This section describes the requirements for
a single locally installed nitrogen
cylinder for both high- and low-pressure
nitrogen, but the principles apply similarly to remote nitrogen sources.
Warning When you install a nitrogen cylinder, make sure you bolt a standard cylinder
bracket to a solid permanent structure in a manner that meets or exceeds
all local seismic and safety code requirements. Failure to secure the nitrogen
cylinder can cause injury to the operator.
2.4.1 Regulator configuration
A single nitrogen source for both high- and low-pressure supplies—
• High pressure for injecting and removing the matrix.
• Low pressure for rinsing the capillaries and operating the cathode and
anode stages and the service door.
Note: If you are using multiple instruments, contact MegaBACE System
Technical Support for the recommended configuration. See Assistance in the
preface for contact information.
Warnings Do not attempt to adjust the regulators to pressure settings above those described
in this guide and in the MegaBACE instrument user’s documentation. If you are
using separate cylinders for high and low pressure, make sure that the correct
pressure is applied to each line.
The nitrogen pressure in the high-pressure line must not exceed 6.89
×
10
3
kPa
(1 000 psi). Never apply high pressure to the low-pressure line. This can damage
the instrument or the low-pressure line and can cause injury.
Use only hose types with ratings that exceed the required operating pressures.
Do not use a frayed or damaged hose, which can rupture and can cause injury.
