Rack Mounting

UL guidelines for rack mounting

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

DVS 510 in 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. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

•Reduced air flow — Install the equipment in the 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 the use of power strips).

Rack mounting procedure

The DVS 510 scaler is delivered with MBD 249 mounting brackets attached. For optional rack mounting, do not install the rubber feet.

Mount the scaler in the rack as follows (see figure 52 on the next page):

1.Insert the unit into the rack and align the holes in the mounting brackets with the holes in the rack.

2.Use four machine screws (provided) to attach the brackets to the rack.
