2.3.6 Connecting the Power Supply
Please ensure that you have the Autosampler connected correctly to the
M420 Series Instrument before connecting it to the power supply.
The electrical connection to the external power supply is made at rear
of the instrument, see Figure 3.2.1.
The universal external power supply will operate from an input supply
in the range 90V to 240V a.c., 50Hz or 60Hz. Please ensure that the
mains supply you are using is suitable.
Fit a suitable 3-pin plug to the a.c. supply lead. Check that the correct
colour coded leads are connected to the plug terminals. Follow the plug
manufacturer’s fitting instructions.
CAUTION
Ensure that the green/yellow earth connector in the a.c.
supply lead is connected to a properly grounded earth
point, the brown lead is connected to the Line terminal
(L) and blue lead is connected to the Neutral terminal
(N).
The mains power cable (471 71 900), constructed to British Standard
1363, should be connected to the IEC socket on the External Power
Supply.
A good ground (earth) connection is essential for satisfactory operation
of the power supply and the safety of the user. The mains plug must
only be inserted into a socket outlet provided with an earth contact.
This protective action must not be negated by the use of an extension
cable without a protective conductor.
WARNING:
Any interruption of the protective conductor
inside or outside the power supply is likely to
make the unit dangerous.
2.3.7 Fitting the Safety Cover
Align the slot in the front of the Safety Cover over the Autosampler
Probe and at the same time locate the Metal Pin on the right hand
bottom end of the Safety Cover into the slot in the front of the
instrument housing. Push the top of the Safety Cover onto the rounded
top cover. This is a snug push fit.
Note: The right hand top edge should be flush with the
housing to ensure that the magnetic sensor functions
correctly.
