KV2 Audio EX26 - Manual (Page 7)

AC Cable Colour Coding
If the colours referred to in the diagram don’t
correspond to the terminals in your plug, use
the following guidelines: Connect the blue wire
to the terminal marked with a N or coloured
black. Connect the brown wire to the terminal
marked with an L or coloured red. Connect
the green and yellow wire to the terminal marked
with an E or coloured green or green and yellow.
Safety Summary
To reduce the risk of electric shock, disconnect
the loudspeaker from the AC mains before
installing audio cable. Reconnect the power
cord only after making all signal connections.
Connect the loudspeaker to a two pole,
three-wire grounding mains receptacle.
The receptacle must be connected to a fuse
or circuit breaker. Connection to any other
type of receptacle poses a shock hazard and
may violate local electrical codes. Do not
allow water or any foreign object to get
inside the loudspeaker. Do not put objects
containing liquid on or near the unit. To
reduce the risk of overheating the loudspeak-
er, avoid exposing it to direct sunlight. Do not
install the unit near heat-emitting appliances,
such as a room heater or stove. This loud-
speaker contains potentially hazardous volt-
ages. Do not attempt to disassemble the unit.
The unit contains no user serviceable parts,
repairs should be performed only by factory
trained service personnel.

Current Requirements
Each EX26 requires approximately 4 Amps
max at 115V AC for proper operation. This
allows up to three EX26’s to be powered from
one 15 A breaker at 115V and up to seven
EX26’s at 230V.
The EX26 presents a dynamic load to the AC
mains, which causes the amount of current to
fluctuate depending on quiet or loud operat-
ing levels. Since different cables and circuit
breakers heat up at varying rates, it is essential
to understand the types of current ratings and
how they correspond to circuit breaker and
cable specifications.
The maximum long-term continuous current
is the maximum rms current during a period
of at least ten seconds. It is used to calculate
the temperature rise in cables, in order to select
a cable size and gauge that conforms to
electrical code standards. It is also used to select
the rating for slow-reacting thermal breakers.
The burst current is the maximum rms current
during a period of approximately one second,
used to select the rating of most magnetic
breakers and to calculate the peak voltage
drop in long AC cables according to the formula:
V pk (drop)= I pk x R (cable total)
The ultimate short-term peak current is used
to select the rating of fast reacting magnetic
breakers. Use the table below as a guide
when selecting cable gauge size and circuit
breaker ratings for your operating voltage.
