The overall useful life of any electronic equipment can vary based on the environmental conditions they are exposed to where they are installed. The following are critical to the lifecycle of the PSU and continued health of the system.
Humidity
Humidity levels should be maintained between 40% and 60% with fluctuations of less than 6% rate-of-change per hour. If humidity is substantial, conditioned air along with humidity monitoring within the cabinet may be needed. During maintenance, look for traces of condensation anywhere in the cabinet – this is a signal that the climate control is beginning to fail.
Corrosion
Look at the paint and exposed metal surfaces within the cabinet for visible signs of corrosion. Corrosive salts and chemicals are kept out of the cabinet by keeping the door closed. Be aware of metallic debris such as airborne zinc that originates from the underside of raised floor tiles commonly used in computer rooms or any nearby hardware assembly or construction activities. If deterioration occurs that you can see, then even further damage is occurring in the components you cannot see and actions should be taken to further reduce contaminants.
Check the surfaces of the PSU and the bottom of the cabinet for dust and if an excessive concentration is found, remove the dust with a soft anti-static brush and vacuum within the cabinet. Replace the cabinet fan dust filters regularly. The specific filter will vary based on the cabinet installed.
Cabinet Fan and Seals
Ensure the cabinet fan is operational, the filters are clean and not obstructed, that protective plates and covers are secure, and that all cabinet penetrations are sealed. This is essential for avoiding premature PSU failure. A new fan assembly may be ordered under Honeywell part number FC-FANWR-24R. Honeywell recommends replacing the fan every 8 years of operation. The
Safety Manager Systems Troubleshooting and Maintenance Guide section 5 and the Fail Safe Controller FSC Service Manual section 7 provide further guidance.

FC-PSU-UNI2450U V2.1 Safety Manager System Power Supply
Honeywell has made several advancements to the SMS Power Supply based on observations from the field. The design and manufacturing techniques have been altered to increase the ability to withstand dust build up across the High Voltage circuit.
These modifications make the unit more robust against adverse environmental conditions which can lead to failure.
The above changes have been incorporated into PSU version 2.1. This version has been in production since August 2012 and the results in the field prove these enhancements are performing as intended and will increase the overall lifespan of the PSU.
This reduces the risk of failure and unplanned downtime adding additional stability to your Safety System.
Normal temperature is maintained at 35 Deg C and a fully loaded PSU could experience a shorter life based on the temperature reflecting the importance of maintaining the fan operation. Many safety systems utilize a redundant power supply such that under normal operation each unit carries 50% of the load. Additionally, the PSU load is generally specified with spare capacity. For example with a minimum of 25% spare capacity, each PSU worst case only carries 40% of the load. In this configuration, temperature and load are not limiting the PSU reliability. Other factors such as dust and humidity become the limiting factors although the wide variation of these environmental conditions makes an exact life expectancy unknown.
