Is my UPS “Hot-Swappable”?

If N+1 is purchased, YES! If your system is not configured for N+1, each power module supplies 10KVA of power, so if you are running 20KVA of load on a 40KVA system you can swap power modules because the system will remain running on 30 of 40KVA, easily picking up your 20KVA load until the new power module is installed. For batteries, the same applies. If at least one extra battery string is provided, the UPS can operate fully protected while the battery modules are replaced one at a time.
