SETUP PROCEDURE
1. Wire the motor and the motor starter device according to the wiring diagrams examples. A forward (clockwise) rotating field is
assumed for normal operation. A anti-clockwise rotating field triggers a fault message.
2. Turn TON/TOFF dial fully clockwise, MON and MOFF dials fully anti-clockwise, and Ie dial to the required current.
3. Connect voltage and start the motor using control inputs R and L.
4. The starting time is set by turning the TON dial anti-clockwise and the starting torque is set by turning the MON dial clockwise to the
desired value. If set correctly, the motor shall swiftly accelerate to the nominal speed.
INSTALLATION INSTRUCTIONS
• Install the motor starter on the DIN rail, as shown on fig. 1.
• Wire the motor starter to the control side. AWG #22 (0.5mm²) minimum, AWG
#14 (2.5mm²) maximum.
• Wire the motor starter to the output side. AWG #30 (0.05mm²) minimum, AWG
#12 (4 mm²) maximum (stranded/solid).
• Maximum terminal screw torque control side 3.46 lb-in (0.39 Nm) & output side
5-7 lb-in (0.564-0.79 Nm).
• Use 60°C / 75°C copper conductors only.
• If multiple units are installed, be sure to follow derating curves.
WARNING! Latching system could be damaged if
product is removed incorrectly out of the DIN rail.
Safety Notes:
- Never clear a fault when the device is switched on.
- The user must ensure that the device and the necessary component are mounted and connected according to the locally applicable regulations and
technical standards (UL, VDE, TÜV, BG).
- Adjustments may only be carried out by qualified specialist staff and the applicable safety rules must be observed.
- After a short circuit the motor starter is damaged and has to be replaced (Assignment type 1).
- If several motor starter devices are protected together, the sum of the motor currents must not exceed 25 A.
When designing circuits with this motor starter unit, components
that generate magnetic fields like contactors, transformers, or high
current wires, should not be placed close to the current sensor.
