Q. How do I connect the SUB 2 to a 240-volt line? Does my Dealer need
to pre-wire a 240-volt outlet in my listening room to ensure the highest
possible performance?
A. In addition to a 15-amp 120-volt cord we include a 15-amp 240-volt
IEC connector/cord with each SUB 2. On our cord, the female end
looks normal, the male end has the blades turned 90 degrees to flat.
These cords can also be bought or made. Existing outlets may be
converted as follows:
The following information is included as an FYI ONLY: This work should be
completed by a qualified electrician only.
IMPORTANT: This procedure is NOT to be used with
"Edison" type circuits (i.e. where a red and black pair
of circuit wires feeding outlets share a single white
neutral.) Check inside the circuit breaker panel to verify
the circuit type. Also check to see that only a black (or
other colored wire) and white wire are present feeding the
outlet to be changed. A green or bare wire should also
be present for proper grounding. Presence of another
colored wire (often red) run with a black and a white wire
generally indicates an Edison Circuit. However, if there is
one white wire for each line conductor in the run between
the breaker panel and the plug, this is not an Edison
circuit and it is then okay to use the following procedure:
CONNECTING
1. Turn power OFF at breaker box for selected outlet;
2. Under ideal conditions, one would select an existing dedicated outlet fed
3. If there is a chain of outlets on a circuit, select an outlet that is
SUB 2 TO A 240-VOLT LINE
from a single circuit breaker. There should be three wires feeding this
outlet: a black, white and green wire (sometimes the green wire is
bare copper). The color of the hot wire is not important as long as there
is a "hot" (120 volts), a neutral (zero volts) and a ground wire present.
If the selected outlet is dedicated (one outlet on the circuit breaker), skip
to Step 4.
conveniently located, remove it and then remove the rest of the
receptacles on the same circuit in the following manner:
a)
Remove all of the outlets on the circuit and disconnect all of the
wires. Check the stripped wire ends for damage or the possibility
of wire stress and re-strip if necessary;
b)
Attach red tape around all of the white (neutral) wires for safety.
Red tape indicates that 240 volts may be present and white is
not to be regarded as a neutral to anyone who might open the
outlet box at a later date;
c)
Using wire nuts, reconnect, by color, all of the wires removed
from the receptacles – white to white, black to black, etc. If
there are no wires to connect with wire nuts at a particular
location, cap off the wires anyway;
d)
Cover all of the non-essential outlet boxes with an appropriate
blank plate leaving the selected outlet unfinished for now.
