Rack mounting
UL requirements for rack mounting
The following Underwriters Laboratories (UL) requirements pertain to the installation of an IN3254 DA onto a rack.
1. Elevated operating ambient — If installed in a closed or
2. Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
