Setting up the TTI-7-R
2.3 Voltage selection and fuse rating
The AC Power Input Unit incorporates a voltage selector and fuse
holder, to enable the TTI-7-R operating voltage and fuse rating to be
selected for the local AC electricity supply. The table below describes
the correct voltage selection range and fuse to use.
Voltage Selection
Voltage Range
Fuse Type
100V 90-110V T630mA (250V AC)
120V 108- 132V T630mA (250V AC)
220V 198-244V T315mA (250V AC)
240V 216-264V T315mA (250V AC)
WARNING: DO NOT CONNECT THE POWER
CABLE UNTIL THE VOLTAGE AND FUSE RATING
OF THE INSTRUMENT HAVE BEEN CHECKED
AND CHANGED IF NECESSARY.
2.3.1 Setting the Voltage and Fuse Rating
Lever open the Power Input Unit from the top with a flat bladed
screwdriver. Inside is a plastic cam: remove this and replace it so that
the voltage to be set is displayed through the window as detailed in
Figure 2.1.
Where fused plugs are connected to the AC power cord, the correct
fuse rating is 3 Amps. The AC power cord provided with the TTI-7-R is
colour coded in accordance with national standards to match the plug
type fitted, as follows:
