Checking your spare inventory regularly can add a significant degree of surety that when you need your spare, it is fully functional. It should be noted that depending on your storage conditions, capacitors can dry out and static build up in the storage environment can damage your spares making them unavailable at your most critical times. 

Load testing of AC and DC Drives guarantees that your drive can sit on the shelf with the assurance that when you need it, it will work. This is a standard on all our service repairs to drives.
