Arcam 290 - Installation Procedures; Mains Safety Guidelines; Mains Plug and Wiring Safety; Mains Supply Connections

INTRODUCTION
This manual is in 4 parts:
1. This section has information relevant to
both the Delta 290 and Delta 290P. This
includes Warnings and Cautions on use
and details of how to bi-wire your
loudspeakers.
2. D290 integrated amplifier operating
instructions.
3. D290P power amplifier operating
instructions. (The Xeta 290P power
amplifier has different front panel
graphics but is functionally identical).
4. Using the D290&D290P together to bi¬
amp your loudspeakers.
N.B. Circled numbers eg © refer to items on
the diagrams inside the flap of the front
cover.
INSTALLATION
® Check that your mains supply voltage
agrees with the voltage setting indicated
on the rear panel of the unit.
■ If your mains supply voltage is different,
consult your Arcam dealer.
MAINS SAFETY
■ This product is normally supplied with a
moulded mains plug already fitted to the
lead. If for any reason the plug needs to
be removed, it must be disposed of
immediately and securely, as it is a
potential shock hazard when inserted into
a mains socket.
■ If the plug is removed then the remaining
lead must be rewired as follows:
■ The blue wire must be connected to the
terminal which is coloured blue or
marked with the letter N.
■ The brown wire must be connected to
the terminal which is coloured brown or
marked with the letter L.
■ The green and yellow wire must be
connected to the terminal which is
coloured green and yellow, or marked
with the letter E or the safety earth
symbol.
■ When replacing the fuse in the supplied
moulded mains plug, the integral fuse
holder/cover must always be refitted.
■ Warning: This apparatus must be
SAFETY STANDARD
■ This product has been designed to meet
the IEC 65 international electrical safety
standard.
MAINS SUPPLY CONNECTIONS
<2> Insert the IEC line socket of the mains
lead fully into the power inlet on the rear
panel. Connect the other end to your
mains supply.
CAUTION: Your Delta 290 and D290P
generate heat when in use, particularly at higher
volumes. It is therefore most important never to
obstruct the ventilation slots on the top and
bottom of the unit as this will cause overheating.
If the temperature of the internal heatsinks rises
above a safe level, then a thermal cut out within
the amplifier will operate.
The POWER LED on the front panel will turn
amber and the output protection relays will
temporarily remove the feed to the loudspeakers.
The system will reset itself as the heatsinks cool
down.
Please note that under certain extreme
conditions it is possible for the Delta 290 or
D290P's thermal cut out to operate when
playing music at very high levels.
