Follow all SAFETY INSTRUCTIONS as well as DANGER and OBLIGATION warnings3. Never incorporate equipment or accessories not approved by L-ACOUSTICS®4. Read all the related PRODUCT INFORMATION documents before exploiting the systemThe product information document is included in the shipping carton of the related system component.5. EnvironmentsUse the product only in E1, E2, E3, or E4 environments according to EN55103-2 standard.6. Radio interferenceA sample of this product has been tested and complies with the limits for the EMC (Electro MagneticCompatibility) directive. These limits are designed to provide reasonable protection against harmful interferencefrom electrical equipment. However, there is no guarantee that interference will not occur in a particularinstallation.7. Power cord cautionDo not use the product if the power cord is broken or frayed.Protect the power cord from being walked upon or pinched - particularly at the plugs and the point where thepower cord exits from the apparatus.8. Mains supplyOnly connect the LA8 (CE type) or LA8US (US type) to an AC power outlet rated 230 V, 16 A, 50 - 60 Hz or120 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.9. Three-phase circuitVerify that each phase works, in particular the neutral one.Balance the loads between the three phases.Never try to reproduce a 230 V circuit connecting an LA8 or an LA8US to two live wires of a 120 V three-phasecircuit.Never try to reproduce a 200 V circuit connecting an LA8JP to two live wires of a 100 V three-phase circuit.10. Electrical generatorYou must power on the generator before powering on the amplified controllers.Verify that the amplified controllers are turned off before powering on the generator.11. Thermal circuit breakerAlways 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).12. GroundingTo plug the controller to mains only use an outlet fitted 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 If the local outlet is obsolete ,consult an electrician.The product is fitted with a grounding-type plug. Do not defeat the ground wire connecting the plug’s femalecontact to the product’s chassis.13. Plug replacementIf the AC plug on the power supply cord of this product does not match the local outlet, it must be replaced by anappropriate one. This operation should only be performed by qualified service personnel.Verify that the cut-off plug is withdrawn from use, as it can cause severe electrical shock if connected to an ACoutlet.
