Tower Installation

Attach the appropriate feet to the unit and place it in a well ventilated area. The tower can
be placed on its side (horizontally) on a hard surface with the cover latch facing up or placed
standing up (vertically) on a flat surface.

Rack Installation

This section provides information on installing the recorder into a rack cabinet. Rack
installation requires the use of the rack mount kit, which is included with the VNM Recorder.
There are a variety of rack cabinets on the market, which may mean the assembly
procedure will differ slightly. If necessary, refer to the instructions that came with the rack
cabinet to complete the rack installation.

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.
Consider the equipment nameplate ratings 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).
