6.2 Alencon Isolated Disconnect (AID) 

Alencon offers a 4-input fused disconnect box (fuses are optional). Both positive and negative 
terminals of PV strings are isolated from the SPOT when the Switch is in the OFF position.

The AID may be mounted on the side of SPOT or on a separate Unistrut hanging plate and wired 
directly into SPOT inputs. 

 6.3 Third Party Disconnects 

Third party disconnect switches can be used such as IMO’s DC isolators, though the other 
options are recommended instead. A typical IMO DC-isolator is shown below in Figure 11.
