Installation
Ventilation
To maintain moderate operating temperatures, the LA8 is equipped with fans providing front to rear airow.
Ventilation instructions
Ensure the front foam lter is clean and dirt free.
Do not block the front and rear ventilation grills.
Ventilation when rack-mounted
Do not block the ventilation grills with front or back panels or doors. If not possible, use a forced-ventilation
system.
When stacking more than one controller in a rack, mount them directly on top of each other or close any open
space in the rack with blank panels.
Connecting to AC mains
Electrical specications
AC mains specications
Only connect the LA8 (CE model) or LA8US (US model) to an AC power outlet rated 230 V, 16 A, 50-60 Hz or
120 V, 30 A, 50-60 Hz.
Only connect the LA8JP (Japan model) to an AC power outlet rated 100 V, 30 A, 50 - 60 Hz or 200 V, 15 A,
50-60 Hz.
To plug the controller to mains only use an outlet tted with a pin tied to ground.
Do not defeat the ground pin of the outlet as it connects the controller to earth. If the local outlet is obsolete,
consult an electrician.
The following table gives the LA8 power data in nominal use (4 Ω, 1/8 of maximum output power. Refer to section
Power consumption
(p.20)).
Voltage (V)

If the mains voltage value increases up to more than 142 V, the amplied controller automatically switches to the 230
or 200 V mode.
If the mains voltage value decreases down to less than 132 V, the amplied controller automatically switches to the 120
or 100 V mode.
Three-phase circuit
When the product is used in a three-phase circuit, verify the electrical conformity and
compatibility of the three-phase circuit.
Verify that the three phases work, and balance the loads between the three phases.
Verify that the neutral and earth work.
Never try to emulate a 230 V circuit connecting an apparatus to two live wires of a 120 V three-phase circuit.
Never try to emulate a 200 V circuit connecting an apparatus to two live wires of a 100 V three-phase circuit.
Circuit breaker
Always interconnect a thermal circuit breaker between the product and the mains.
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).
