G-Size Chassis Information:
The G-size chassis (1533×326×545mm) is the largest chassis in the MM430 series, covering power ratings 160kW-250kW. The larger enclosure provides enhanced thermal management for the highest power applications.

Selection Guide:
The 160kW model is the entry point to the G-size chassis. Choose 160kW when your pump or fan motor is rated 160kW or when the 132kW FX-size model is insufficient. For higher power, consider the 200kW or 250kW models within the same G-size family.

Important Notes:
- This product is discontinued. Available ONLY as a spare part
- A BOP or AOP is required for parameter changes beyond factory defaults
- SINAMICS G120 series is the recommended successor for new designs

FAQ:

Q1: What is the output frequency range for this model?
A: For power ratings 110kW and above, the output frequency range is 0-267Hz [8†L17-L18].

Q2: What is the typical efficiency of this drive?
A: For 110kW-250kW models, efficiency is 97%-98% [8†L19].

Q3: What physical clearance is required for installation?
A: The G-size chassis (1533mm height) requires significant vertical clearance. Allow 100mm above and below the drive for proper air circulation. Plan cabinet layout carefully.

Q4: Does this drive include a built-in EMC filter?
A: No. This is the unfiltered version (GB0 suffix). For EMC compliance, external filters are available as accessories.

Q5: Can this drive be used for multi-pump control?
A: Yes. MM430 includes built-in multi-pump staging logic. Using the relay outputs, it can sequence additional pumps based on system demand.
