TERMINAL BLOCKS INSIDE OF THE TERMINAL BOX
Terminal block X1 (in the control circuit):
RT1 – temperature sensor;
TK1 – self-resettable thermal switch (normally closed contact), response tempe50 °C;
TK2 – manually resettable thermal switch (normally closed contact), response tempe90 °C;
Connect the thermal switch contacts in series to the circuit of the starter (contactor) actuating coil that starts the unit or the heater. In
case of overheating one of the contacts gets broken and switches the starter actuating coil off to cut power off and stop the motor.
Terminal block X2 (heaters):
L1, L2, L3 – phases (for AOE 9,12,15);
1L1, 1L2, 1L3, 2L1, 2L2, 2L3 – phases (for AOE 18,24,30);
N – neutral;
PE – protecting grounding.
Terminal block X3 (fan):
L – phase;
N – neutral.
The fan, the heaters, the thermal switch and the temperature sensor are mounted on side of the unit, refer to the wiring diagram in page
11.
