Mounting

Plenum Placement

The MPA 401-70V and MPA 401-100V amplifiers meet UL 2043 requirements for heat and smoke release. They can be installed in the ceiling, out of sight, with reduced risk of theft.

ATTENTION: Although the amplifier is plenum rated, the	power supply provided with
it is not. The power supply must not be placed in the plenum space. Cables to and
from the amplifier must also be plenum rated. The DC	power cord provided with
the unit is not plenum rated.

Tabletop Placement

Attach the four provided rubber feet to the bottom of the unit and place it in any convenient location.

Rack Mounting

UL Guidelines For Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:

1.Elevated operating ambient temperature — If the unit is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma: +122 °F, +50 °C) specified by Extron.

2.Reduced air flow — Install the equipment in the rack so that the equipment gets adequate air flow for safe operation.

3.Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

4.Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of the equipment nameplate ratings should be used when addressing this concern.

5.Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).
