Main Power Switch
External Connections
The main power switch must be turned 90° clockwise/anti-clockwise to
switch on/off the instrument (see Figure 1-8). Placing the main power
switch in the Off position turns off all power to the LTQ Orbitrap XL
(and linear ion trap as well, including the vacuum pumps).

Note When the main power switch is in the Off position, you can secure
it with a padlock or a cable tie (to prevent unintended re-powering when
performing maintenance, for example). ▲
Figure 1-9 on page 1-11 shows the lower right side of the instrument
with the external connections for mains supply, gases, cooling water, and
Ethernet communication.
The power connector for the mains supply is located on the center. The
cooling water ports are located below the power connector. (See also
topic “Cooling Water Circuit” on page 1-28.) A Teflon® hose connects
the instrument to the nitrogen gas supply. An analogous port is used for
the HCD collision gas supply. Metal tubing connects the instrument
with the helium gas supply. (See also topic “Gas Supply” on page 1-25.)
Located at the top are two ports for Ethernet cables for connecting the
LTQ Orbitrap XL and the linear ion trap via an Ethernet hub with the
data system computer.
The exhaust hose from the rotary pumps is led backwards below the
instrument, comes out the back of the instrument, and connects the
pumps to the exhaust system in the laboratory.
