Surface mounting
Step 1: Locate and drill screw holes based on the installation size of the surface.
Step 2: Use four M4×8 cross recessed pan head screws with M4 nuts to mount MT50
Surface onto the panel.
Step 3: Mount the four associated white screw plugs into the screw holes.
Note: Take full consideration of the plugging/unplugging space of the
communication cable and the cable's length during installation to see if they are
appropriate.

The controllers' parameters are displayed below:
Operational tips: and buttons are respectively used to turn the browse page
upward and downward.
4.5 Test operation
Load switch test operation is conducted on the connection solar controller to see if
the load output is normal. The test operation does not affect the working settings
under actual load, which means that the solar controller will exit from the test mode
when exiting the Test Operation page.
