6.2 Cooling
The amplified controller uses a forced air cooling system to maintain a low and even operating temperature. All fan

amplified controllers have front to rear airflow. Therefore when stacking more than one unit in
a rack, mount units directly on top of each other or close any open space in the rack with blank panels.
If the controller is rack-mounted do not block front or rear air vents with front or back panels or doors. If
this cannot be achieved a forced ventilation system has to be used.
If the controller is installed in an enclosed rack the open area at the back of the controller must be at least
140 cm

per controller.
Ensure that the front filter system is clean and dust free [8.1].
6.3 Connecting to AC mains
6.3.1 Operating voltage
Operating voltage range and frequency are indicated on the controller back panel.
Only connect the controller to an appropriate AC circuit and outlet.
If the output voltage of the AC mains is unsure consult an electrician.
The following table gives the nominal data of the power supply for LA8 in normal use (4 Ω, 1/8 of maximum output
power [6.5]):

If the mains voltage value increases up to more than 142 V the amplified controller will automatically switch to the 230 or 200 V mode.
If the mains voltage value decreases down to less than 132 V the amplified controller will automatically switch to the 120 or 100 V mode.
6.3.2 Three-phase circuit
VERIFY the electrical conformity and availability of each connection, in particular the neutral one.
BALANCE the loads between the three phases.
NEVER connect an LA8 or LA8US to two live wires of a 120 V three-phase circuit (in order to use it in the
230 V mode).
NEVER connect an LA8JP to two live wires of a 100 V three-phase circuit (in order to use it in the 200 V
mode).
6.3.3 Electrical generator
FIRST power the generator on and THEN power the amplified controllers on.
VERIFY that the amplified controllers are turned off before powering the generator on.
6.3.4 Circuit breaker
ALWAYS interconnect a thermal circuit breaker between the product and the mains supply.
The circuit breaker current rating depends on the mains voltage rating as follows:
16 A for 230 V or 30 A for 120 V (LA8 or LA8US), 15 A for 200 V or 30 A for 100 V (LA8JP).
