3.2 Cooling
Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and
out through the back. It is of course essential that, while the power amp is running, the air is able to circulate around it
freely. The efficiency of the cooling will depend on both the immediate environment (e.g. an enclosed rack, direct sunlight)
and if the front filter is clogged. If the amp is installed in a case, the open area at the back of the case must be at least 140
cm2. This area should be in line with the amp. If this cannot be achieved, a forced ventilation system has to be used.
3.3. Mains
3.3.1 Mains supply
Only connect the LINUS5-C amplifier to an appropriate AC circuit and outlet in accordance with the requirements indicated
on the rating plate. Only use mains cables with original Neutrik powerCON
®
32 A connectors for safety reasons.
For installation mains cable and amplifier protection, we recommend the use of a 16 A mains breaker with C-type tripping
characteristic for 230 V operation for each LINUS5-C amplifier (or a 30 - 32 A breaker for 115 V operation respectively).
Please do NOT use much larger mains breakers than recommended here and especially do NOT connect several
LINUS5-C amplifiers to one single (very large) breaker.
Always respect this rule of thumb for good installation practice for guaranteeing long term reliable, robust and safe
operation:
one LINUS5-C - one circuit breaker.
As soon as the amplifier is connected to mains, the primary capacitors are charged through the inrush current limiter.
At the same time the auxiliary power supply is activated, powering the main controller and the display. This allows
powering up the main SMPS from the switch on the amplifiers front panel.
NOTE: Turning the amplifier off from the user interface (1/0 switch) does not disconnect the amplifier from mains.
Disconnecting the amplifier from the mains can only be achieved by physically removing/disconnecting the mains
cable. The mains cable therefore has to be freely accessible at all times.
Attention: Never unplug the powerCON® connector while the amplifier is playing music.
Always turn the amplifier off from the front panel before disconnecting the powerCON®connector.
Alternatively, you can disconnect the amplifier from the mains via an external all-pole disconnection (e.g. a mains breaker).
Disconnect the mains cable during a lightning storm or when the amplifier remains unused or unsupervised for a
prolonged period of time.
If a power cut occurs while the amplifier is switched on, it will restart auto matically once the mains distribution has been
restored. All settings prior to the loss of power will be maintained.
