Installation and Operation

Mounting the Scaler

The DVS 304 is 1U high, half rack wide, and is rack mountable. Alternatively, it can be placed on a table or other furniture. Rubber feet and rack mounting hardware are included.

The 1U high and full rack DVS 304 A (audio model) can be rack mounted using included rack/through-desk mounting brackets.

Tabletop/desktop placement

Four self-adhesive rubber feet are included with the DVS 304. For tabletop use, attach one foot to each corner of the bottom side of the unit and place the unit in the desired location.

UL guidelines for rack mounted devices

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the DVS in a rack.

1. Elevated operating ambient temperature — If 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 DVS 304 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 a rack so that the amount of air flow required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.

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 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 (e.g. use of power strips).
