IN1606 and IN1608 Series Scaling Presentation Switcher • Reference Information 101

UL Guidelines for rack mounted devices

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

1. 

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, install the scaler 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 no 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).
