AC Power Cord Socket
AC power cord socket / Power on/off
switch
AC power is connected to the back of the
DSP-4P. A single module contains the
on/off switch, the power cord socket and
the main safety fuse holder. The processor
can be powered by 230 VAC or 110 VAC.
The normal factory setting of 230 VAC can
be recognized from the fact that the "220 -
240 V" label is in the upright position, and
that the arrowhead adjacent to it is the
one pointing toward the small, white solid
rectangle on the lower border below the
fuse compartment. The voltage setting
must be correct for the AC (mains) voltage
in your region of operation.
The AC voltage setting / Changing the
fuse
The fuse compartment on the back of the
DSP-4P provides the means for setting the
power supply voltage:
To change the setting, unplug the AC
power cord from the socket and insert the
tip of a flat-blade screwdriver into the slot at
the lower edge of the power cord socket
(see photo above on the right side).
Carefully pull the fuse compartment out. To
facilitate changing the fuse, unfold the small
tabs that are on either side of the fuse holder:
When the proper value fuse has been
inserted, turn the fuse holder so that the
intended voltage label is right-side-up, and
carefully slide the fuse compartment back
into the DSP-4P.
Please note:
Both a 100 mA and a 200 mA fuse are
supplied, each in the corresponding position
of the compartment.
The fuse rating for 230-Volt operation must
be 100 mA, and for 110-Volt operation, 200
mA (slow blow in both cases); fuse size is 5
x 20 mm or 6 x 30 mm. It is important for
the fuse to be a 230-Volt type even if the
actual AC voltage to be used is much lower.
Also, when changing the unit from 110- to
230-Volt operation it is important to install
the lower-rated (100 mA) fuse. A 200 mA
fuse at 230 Volts would not provide ade-
quate protection; operating the unit in this
manner is potentially unsafe and will void the
unit's warranty.
Under no circumstances should any
other type of value of fuse be used other
than the types and values given above.
If fuses burn out continually, send the unit
to the factory, dealer or representative for
repair.
