Commissioning MindConnect Element

Objective

The MindConnect Elements should be connected to the power supply and commissioned.

Requirements

  • The protective conductor is connected (valid only for MindConnect Nano). Refer to the chapter Connecting the protective earth.

  • A two-core cable with a cable cross-section of 0.75 mm² to 2.5 mm².

  • A slotted screwdriver with a 3 mm blade.

NOTICE

Power supply requirements

MindConnect Nano should only be connected to a 24 V DC to power supply which satisfies the requirements of safety extra low voltage (SELV) according to IEC/EN/DIN EN/UL 60950-1.

MindConnect IoT2040 should only be connected to a 9...36 V DC power supply which meets the requirements of safe extra low voltage (SELV) according to IEC/EN/DIN EN/UL 60950-1.

The power supply must meet the NEC class 2 or LPS requirement in accordance with IEC/EN/DIN EN/UL 60950-1.

NOTE

The MindConnect Nano/IoT2040 package does not include power supply. The appropriate power supply product from Siemens with the name SITOP can be used.

Procedure

CAUTION

Danger of burns

The surface of the device can reach temperatures of over 70 °C. Any unprotected contact may cause burns.

Avoid direct contact during operation of the device. Touch the device only with appropriate protective gloves.

  1. Switch off the power supply on the device.
