7. Installation & Wiring

7.1 Mechanical Installation

1. Mount directly on SEW DRS/DRE/DRP series motor flange.

2. Tighten mounting screws to 3.0 Nm.

3. Ensure adequate ventilation; avoid heat sources.

7.2 Electrical Wiring

1. Power (L1/L2/L3/PE): 3‑phase 380–500 V AC, proper grounding.

2. Motor (U/V/W/PE): Shielded cable to motor terminals.

3. Control: 24 V DC for run/stop, direction, enable.

4. Communication: RS‑485 for Modbus RTU (optional).

5. EMC: Install external EMC filter on input side.

8. Commissioning

1. Verify all wiring and insulation before power‑on.

2. Set motor parameters and control logic via DIP switches.

3. Power on; steady green LED indicates standby.

4. Test run at low speed; check for noise/vibration, then ramp to speed.

9. Status & Faults

9.1 LED Indications

• Steady green: Ready

• Flashing green: Running

• Flashing red: Fault

9.2 Common Faults

• Overcurrent: Short circuit, overload, or motor fault.

• Overvoltage: Input surge or regenerative voltage.

• Overtemperature: Poor ventilation or high ambient temp.

• Communication error: Cable fault or wrong address.

10. Maintenance

• Clean heat sink every 6 months.

• Check terminal tightness and cable condition regularly.

• Replace damaged seals to maintain IP55.

11. Storage & Disposal

• Store in dry, clean environment within temperature limits.

• Dispose per local WEEE regulations; recycle metal, plastic, electronics.
