Power Supply sources
At least one of the next indoor or outdoor options must be selected in order to setup the Smart Spot device to work. This device needs an external power supply to be turned on.
Indoor
There is an Indoor power supply source with three different terminations depending on the region standard:
- EU connector (type F)
- US connector (type B)
- UK connector (type G)
Outdoor
There are three Outdoor electrical panel options to be selected depending on the deployment requirements:
-
Outdoor electrical panel that includes a fuse holder, differential and a 15 VDC source
-
Outdoor electrical panel that includes a fuse holder, self-resettable differential and a 15 VDC source
