1. Model 6400 / 6405 Spectrophotometer
2. Mains cable
3. Pack 100 disposable cuvettes

2.2 INSTALLATION
The 6400 / 6405 are designed to operate on 230V or 115V (50/60Hz) mains supply.
The standard 2 metre cable supplied with the unit is fitted with an IEC type connector which can be
plugged directly into the POWER IN socket on the rear panel.
The mains fuse is housed within the POWER IN socket. When replacing the fuse the unit should be
disconnected from the mains supply.
In the event of the fuse failing after replacement, it is advisable to consult with the manufacturer or
your local distributor before proceeding further.
Fuse rating:
1.6A (T-type) for 230V operation
3.15A (T-type) for 115V operation
NOTE: The unit should be positioned within 1.5 metres of an earthed mains supply.
VOLTAGE SELECT
NOTE:
When changing the voltage select switch position always ensure the fuse rating is
correct.
Before attempting to change the voltage select, disconnect the unit from the mains supply. Withdraw
the fuse holder from the power input socket and remove the fuse. Extract the grey fuse retainer and
rotate so that the correct voltage is visible through the aperture in the fuse holder. Replace the fuse
retainer in its holder, fit the correct fuse and push the assembly back into the power input socket.
