Safety Symbol and Message Conventions Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first andunderstand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

WARNINGWhen Installing the Unit

• Donotexpose theunit to rainor anenvironmentwhere it may be splashed by water or other liquids, asdoingsomayresultinfireorelectricshock.

• Use the unit only with the voltage specified onthe unit. Using a voltage higher than that which is specifiedmayresultinfireorelectricshock.

• Do not cut, kink, otherwise damage nor modifythe power supply cord. In addition, avoid using the powercordincloseproximitytoheaters,andneverplace heavy objects -- including the unit itself -- on the power cord, as doing somay result in fire orelectric shock.

• Avoid installing or mounting the unit in unstablelocations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling downandcausingpersonal injuryand/orpropertydamage.

• Installtheunitonlyinalocationthatcanstructurallysupport the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/orproperty damage.

When the Unit is in Use

• Should the following irregularity be found duringuse, immediately disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in thisconditionas thismaycausefireorelectricshock.

5. INSTALLATIONTheN-8000AFcanbeinstalledinanyofthreeways:Equipment rack mounting, Desk-top installation, and Wall mounting.

5.1. Equipment Rack Mounting

A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should begiventoinstallingtheequipmentinanenvironmentcompatiblewiththemaximumambienttemperature(Tma) specified by the manufacturer.

B)ReducedAirFlow-Installationoftheequipmentinarackshouldbesuchthattheamountofairflowrequiredfor safe operation of the equipment is not compromised.

C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips)."
