When using the FLEXware 500 or 1000, it is installed in one slot in the DC enclosure.
When using the FLEXware 250, it is not installed inside the enclosure. It is installed externally using the included bracket. It connects alongside the FLEXnet DC Battery Monitor.
When using the GSLC, it is installed in one circuit breaker slot on the DC rail.
If necessary, the slotted holes on the included bracket allow it to be installed in various external locations on the GSLC or the Radian inverter.
