How do I Mount my ETO2 Controller?
Use a DIN Rail to Mount your ETO2 Controller
The ETO2 controller doesn’t mount to a standard North American electrical box. It has a DIN rail on the back of the unit.
So we recommend either putting a DIN rail on the wall or cabinet to mount, or utilizing the four mounting holes (shown below) in the corners of the housing and screw it to a surface.
Please refer to the ETO2 installation manual for further information regarding your controller.
