The mains plug is used as a disconnect device and shall remain readily
operable.
To prevent electric shock do not remove top or bottom covers. No user
serviceable parts inside. Refer servicing to qualified service personnel.
To completely disconnect this equipment from the AC mains, disconnect
the power supply cord plug from the ac receptacle. The mains plug of the
power supply cord shall remain readily operable.
Do not install this device in a confined space.
Check the voltage in your area and use the correct type of mains
connector.

Unpacking and visual checks
Every Lab.gruppen amplifier is carefully tested and inspected before
leaving the factory and should arrive in perfect condition. If any damage
is discovered, please notify the shipping carrier immediately. Save the
packing materials for the carrier's inspection and for any future shipping.

Installation
Wall mounting – For attaching brackets (marked "B" on the drilling guide)
to the wall, please use appropriate means for mounting to a specified load
of 3 kg minimum on each screw. Ensure that all four screws are secured
properly to the wall.
For drywall mounting, use a woodscrew (3.5 mm diameter with 25 mm
minimum length) and 4.5 mm drywall plug with specified maximum
load of greater than 3 kg (e.g. Molly E22412). This method of mounting is
evaluated for North America according to
UL/CA60065.
For mounting on surfaces other than drywall, please ensure that the
method of mounting is suitable for the wall material. Also ensure that the
brackets will be secured to the wall with the appropriate means to ensure
similar load condition as specified above.
To attach the wall brackets "B" to your amplifier, please use the supplied 3
mm Torx machine screws.
Rack shelf mounting – The amplifier can be mounted to a rack shelf
or similar by means of the three holes in the bottom marked "A" on the
drilling guide.
Use a 4 mm diameter machine screw (not supplied), ensuring that the
length of the screw is suitable for the thickness of the shelf. The screws
used should not penetrate into the amplifier for more then
10 – 20 mm after mounting.
Lab.gruppen rack shelf kit – A special dedicated rack mount
shelf designed to hold two LUCIA amplifiers is available from Lab.gruppen.
It includes all necessary accessories, screws, and mounting instructions.
Cooling
Ensure that there is sufficient open space on at least two ventilating
surfaces (top, bottom, front and rear) of the amplifiers to allow for free air
flow. Please refer to the Thermal Dissipation Chart in the full Operation
Manual when installing large numbers of amplifiers in air conditioned
spaces.
LUCIA amplifiers feature intelligent fan control. In low power applications
and with good ventilation, the fan will remain off. At moderate power
levels, the fan may activate in "whisper mode. "
The fan will run at full speed only at elevated output levels, when noise
will be masked by the louder program.

Operating voltage

LUCIA amplifiers have a universal power supply that operates on AC
mains from 100 – 240 V at 50 or 60 Hz. The power receptacle on the rear
panel accepts the supplied IEC cord which terminates in a connector
appropriate for the country of sale.
Grounding
Signal ground is floating via a resistor to chassis, and therefore grounding
(earthing) is automatic. For safety reasons, never disconnect the earth
(ground) pin on the AC power cord. Use balanced input connections to
avoid hum and interference when longer input cables (more than about 1
m/ 39") are used.
