Assembly, Startup, and Dismantling
Assembly: Place the switch on the DIN rail from above
using the slot. Push the front of the switch toward the
mounting surface until it audibly snaps into place.
Startup: Connect the supply voltage to start up the
switch via the terminal block.
Dismantling: Pull out the lower edge and then remove
the switch from the DIN rail.
