6 Isolators / Disconnects
Alencon requires using disconnects (or contactors) to enable an electrical cut-off of the SPOT
from its input power source.
Always disconnect SPOT from input power when performing maintenance on the
SPOT.
Disconnects must be rated to the max input voltage and UL approved
Do not disconnect the SPOT output while under load by disconnecting from the
output. Always use an appropriately rated disconnect to isolate SPOT from input
power before disconnecting the output.

6.1 Alencon Fused Electrical Disconnect (FEED)
Alencon’s FEED
TM
(Fused Electrical Disconnect), see Figure 133, provides a configurable add-on
device to SPOT input and output. Mounted directly onto the SPOT front, the FEED is used to
add disconnects and over-current protection via fuses to PV strings connected to the SPOT. As
well, FEED offers PV grounding with ground-fault detection.
FEED is only available for deployment indoors as it is not weather rated.
See more about FEED options in FEED Manual.
