Installation of SINAMICS G120 Smart Access
1.Power Supply Consideration
- Note: SINAMICS G120 Smart Access has no internal power supply; it directly draws power from the inverter via the RS232 interface.
- Nonvolatile configuration data stored on the Smart Access module is actually kept in its memory; the setting is retained even though there is no external power provided to the module at this point.
2. Fitting the SINAMICS G120 Smart Access to the Inverter
Some of the important guidelines to follow so that it is properly mounted and working on the inverter are as follows.
Verify Proper Inverter Installation:
- Check whether the SINAMICS G120 smart access module has already installed the inverter, provided the installation instructions from Operating Instructions have been followed and the inverter has been done correctly.
- Proper inverter installation prevents electrical and/or operational issues during the integration stage.
Installation Location:
- The SINAMICS G120 Smart Access is mounted in a cabinet.
- During mounting, ensure that during operation, the cabinet door remains open.
- This enhances good signal transmission and avoidance of interference.
- Mounting of the module should ensure adequate clearance to avoid probable issues of airflow or communication signals.
3. Mounting Restrictions
No Door Mounting:
- The SINAMICS G120 Smart Access is not mounted on the door of a control cabinet.
- This restriction means that you cannot mount the module directly on the door of a control cabinet.
- Make sure it is placed on the appropriate mounting surface inside the cabinet to ensure stable operation.
Keeping Distance for Safety:
For safety and to minimize exposure to radio frequency electromagnetic fields:
- The body and SINAMICS G120 Smart Access should be at least 2 cm apart from each other when the module is operating.
- This ensures that the human exposure to electromagnetic fields is always kept within the safe limit during the operation of the module.
4. Final Checks and Considerations
Double-check connections:
- Before powering up the system, all RS232 connections are ensured to be secure and the module is placed appropriately in its intended location in the inverter system.
Environmental Considerations:
- SINAMICS G120 Smart Access should be mounted in an environment that conforms to temperature, humidity, and vibration standards as described in the Operating Instructions to prevent possible operational problems.
- Ensure that there is adequate ventilation in the cabinet so that the module and inverter do not overheat when functioning.
Summary of Key Notes for Installation:
- Power Supply: Derived from the inverter via RS232; no external power needed for retention of configuration.
- Installation of Inverter: Ensure the correct installation of the inverter before the module addition.
- Mounting: The module should be mounted within the cabinet and not on the door.
- Safety: There should be a 2 cm clearance between the module and other objects when in operation to reduce exposure to electromagnetic fields.
- Environmental Factors: Ensure that the environment meets standards to guarantee safety and efficiency.
Following these guidelines and precautions, you are sure to successfully install SINAMICS G120 Smart Access and guarantee the safe and efficient functioning of this system in your industrial control.
