DIN Rail Mount
•
Assembly: Place the switch on the
the slot. Push the front of the switch toward the mounting
surface until it audibly snaps into place
•
Start-up: Connect the supply voltage to start up the switch
via the terminal block (or DC JACK)
•
Dismantling: Pull out the lower
switch from the DIN rail.
