Choosing a Suitable Location for Mounting

The VNM 250 is designed to be used either as a free‑standing unit or mounted in a 19‑inch

rack using optional mounting kits. Wherever the unit is mounted, observe the Environmental

Requirements listed below.

Environmental Requirements

ATTENTION: The points in this section must always be observed whether the

VNM250 is free‑standing or rack‑mounted.

Orientation

The VNM 250 is designed to be used free‑standing on a stable, horizontal surface. It can,

however, be used in any orientation subject to the necessary ventilation requirements.

Temperature

z Do not install or operate the VNM 250 in an area where the ambient temperature

exceeds 35 °C (95 °F) or falls below 5 °C (35 °F).

z The VNM 250 and its associated power supply produce heat, which may affect the

ambient temperature.

z After the VNM 250 has been in use for a period of time, the external casing may

become slightly warm to the touch. Ensure that any adjacent surfaces are not affected

by the heat.

Ventilation

Do not obstruct the ventilation openings during use. The VNM 250 has an integral forced‑air

cooling system. A fan draws air in through the ventilation openings in the front panel and

expels the heated air through the openings in the back panel. The fan speed is controlled

automatically by an internal temperature sensor. The fan may, therefore, appear to run faster

as the unit warms up or if the ambient temperature increases.

A self‑resetting thermal cutoff shuts down the VNM 250 if the temperature exceeds design

limits.

Humidity and water

Do not install or operate the VNM 250 in an area:

z where the ambient relative humidity exceeds 85%

z that is prone to condensation

z near water or in a location that may be prone to water

Mounting Procedures

WARNINGS:

• This equipment must be grounded.

• To avoid the possible risk of electric shock or product damage due to

condensation, always allow the power supply to adapt to the ambient temperature

and humidity for at least 30 minutes before switching it on. This is particularly

important when moving the unit from a cold location to a warm location.

The VN‑Matrix 250 Series encoders and decoders are housed in rack mountable, 1U high,

metal enclosures. Optional mounting hardware lets you install the unit in any standard

19‑inch rack or under or through furniture.

Tabletop Use

For tabletop use, affix one of the supplied self‑adhesive rubber feet to each corner of the

bottom of the unit.

Rack-Mounting

UL Rack-Mounting Guidelines

The following Underwriters Laboratories (UL) requirements pertain to the installation of the

VN‑Matrix 250 into a rack.

Elevated operating ambient temperature — If the equipment 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, consider installing the equipment

in an environment compatible with the maximum ambient temperature (Tma = +122 °F

[+50°C]) specified by Extron.

Reduced air flow — Install the equipment in a rack so that the amount of air flow required

for safe operation of the equipment is not compromised.

Mechanical loading — Mount the equipment in the rack so that uneven mechanical

loading does not create a hazardous condition.

Circuit overloading — When connecting the equipment to the supply circuit, consider

the effect that circuit overloading might have on overcurrent protection and supply wiring.

Consider equipment nameplate ratings when addressing this concern.

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 use of power strips).

Mounting Instructions

Mount the unit in a rack or under or through furniture in accordance with the directions

included with the mounting kit.
