Connecting the Power
Before switching on this unit and connecting or disconnecting any other cable,
the protective earth terminals of this unit must be connected to the protective
ground conductor of the power cord. If you are using an extension cord
(power cable) make sure it is grounded as well.
Any interruption of the protective (grounding) conductor (inside or outside the
instrument) or disconnecting of the protective earth terminal can make this
unit dangerous. Intentional interruption is prohibited.
The line fuse is located in an integral-type fuse holder located on the rear
panel. Make sure that only fuses of the required rating, as marked on the rear
panel, are used for replacement. Do not use repaired fuses or short-circuit the
fuse holder. Always disconnect the mains cable before removing or replacing
the fuse. Whenever it is likely that the fuse protection has been damaged,
make the unit inoperative and secure it against unintended operation.
AC power is supplied to the ASM-61 modem through a standard 3-prong plug
with an integral fuse holder (see Figure 2-1). A cable 1.5m (5 ft) is provided with
the unit.
