1.5 Line Fuses
There are two 5 x 20 mm fuses mounted inside the power entry module. They are
accessible via the snap-in cover. Replace with the correct fuse rating: IEC T Type
(Slow), 4/10 A, 250 V(ac). See
section 4.2.6 on page 4-2 for instruction to replace
the fuse.
1.6 Power Switch
WARNING - Risk Of Electric Shock
Do NOT use the power switch as a disconnecting device;
disconnect the power cord from the power entry module
to fully remove hazardous voltage from inside the TM
monitor.
The power switch is located on the front of the TM monitor. The switch is a toggle
type, marked with
I
and
O
. The
I
(on) position applies the power to the instrument.
The
O
(off) position cuts off the power to the instrument. However, turning the
power switch off does not fully remove the AC power from inside the instrument.
Always disconnect the power cord from the power entry module to fully remove AC
power from inside the instrument.
