Ensure the system is powered down before inserting or removing the module to prevent electrical damage.

FAQs

What is the primary function of the 6ES7407-0KA02-0AA0?

This module acts as the primary power source for the S7-400 backplane bus, converting standard industrial AC/DC voltages into the required 5 V DC and 24 V DC levels for the PLC system.

Does this unit support redundant power configurations?

No, this is a standard power supply module. For redundant power configurations, you must utilize the specific 6ES7407-0KR02-0AA0 model.

What battery is required for memory backup?

This power supply supports the use of a 3.6 V / 2.3 Ah AA lithium battery to maintain RAM contents and system parameters during power loss.

What are the input voltage tolerances?

The module accepts a wide range of inputs, specifically 88 V to 300 V DC and standard 120/230 V AC mains.
