8 AC Mains Input, Switch and Fuse Assembly
A conventional, 15-ampere IEC standard power cord is used with the SC-1.
A high quality AC mains cord is included with the product, although the
use of the standardized IEC receptacle means that you may easily substi-
tute another high quality AC mains cord if you wish.
Warning! Your new Wisdom Audio SC-1 has been safety-tested and is
designed for operation with a three-conductor power cord. Do not
defeat the “third pin” or earth ground of the AC power cord.
An AC mains switch is located just above to the power cord on the rear
panel of the SC-1. This switch may be used to disconnect the unit from the
AC mains without having to actually unplug the SC-1 from the wall outlet.
If you plan to be away for an extended period, or have any other reason to
turn the SC-1 completely off, you may either unplug the SC-1 or you may
use the AC mains switch.
Danger! Potentially dangerous voltages and current capabilities exist within
your SC-1. Do not attempt to open any portion of the SC-1’s cabinet.
There are no user-serviceable parts inside your SC-1. All service of
this product must be referred to a qualified Wisdom Audio dealer or
distributor.
We recommend that care be taken to ensure that all AC plugs for the equipment
in the system be wired so as to ensure proper AC polarity. Doing so will mini-
mize noise in the system.
In the U.S., a simple AC mains tester (found at any hardware store) can test to
ensure that your electrical outlets are wired properly. Elsewhere in the world
(for example, in European Union countries), the AC mains plugs themselves are
not always polarized. Your dealer can test for the proper orientation of the plug
in the outlet. In such a case, it is good practice to mark both plug and outlet to
ensure that all products remain in the proper orientation should it become nec-
essary to temporarily disconnect the system (as for example, during an electrical
storm).
Finally, the Wisdom Audio SC-1 incorporates a fuse block that protects both the
live and neutral (ground) sides of the circuit. If your SC-1 is plugged into an AC
outlet that you know is live (plug a lamp into it as a test), and yet appears to be
off, check the following:
1 Check the AC cord to make sure it is not damaged.
2. Check the AC mains switch to ensure that it is On (the side
with the straight line is depressed, not the “O” side).
3. If that does not resolve the problem, turn Off the AC mains
switch (“O”) and then disconnect the power cord from the AC
mains receptacle.
4. Using a small screwdriver, gently pry open the fuse block cover
at the top edge of the assembly. (You may be able to do it with
just your fingernail.)
