Instrument Overview 21
The back panel of the TomoScan FOCUS LT contains the following elements:
Power entry module
The power
entry module enables the connection of a standard three-lead power
cord with a central ground. The universal-type internal power supply accepts any
voltage level in the range of 100 VAC to 240 VAC, operating at frequencies
between 50 Hz and 60 Hz. Voltage fluctuation must not exceed ±10 % of the
supply voltage range. The fuse rating must be selected according to the power
supply voltage level used.
Please note that the on/off switch is located on the front panel. The TomoScan
FOCUS LT can also be supplied from a DC power source. The
DC IN
connector,
located on the front panel, accepts voltages between 15 VDC and 24 VDC, rated at
5 A.

POWER DISCONNECT
This marking on the back panel indicates that the internal AC power supply is not
disconnected from the AC source when the unit is turned off using the front panel
on/off switch (
). To disconnect the AC source, first disconnect the power cord from
the AC outlet, and then disconnect the power cord from the back of the instrument.
Failure to do so can cause electric shocks.
Fuse and fuse holder
• A fuse holder contains the instrument main fuse. This fuse is used to protect
the TomoScan FOCUS LT from an external power surge or from an internal
short circuit.
• The fuse holder also contains a spare fuse in a small compartment if a fuse
replacement is required (for details, see chapter “Maintenance and
Troubleshooting” on page 35).
