
Use the test outlets on MI 3399 walls for test purpose only and not for
supplying different loads (radio, cooker, lamp etc.) because the components
inside the board (wiring, switches, contacts, resistors etc.) are dimensioned
for test purpose only.

To supply additional loads or instruments use the F0/1 outlet. This outlet is
connected in parallel to mains and not through electronic circuits.

Do not short accessible contacts at one-phase or three-phase outlets.
4.2.1 Connection to a 1-phase outlet
Figure 4-1: Connection of the Application Trainer to one-phase outlet.
After connecting the MI 3399 to the wall outlet check if lights L1, L2 and L3 are ON.
Turn the Application Trainer ON by switching the circuit breaker on the bottom of the
error switch panel (4 in Figure 4-4: Parts of the Application Trainer explained.). When
the switch is turned ON, lights L1, L2 and L3 should light up.
If lights L1, L2 and L3 do not light up, check chapter 4.2.3 Error handling for further
information.
