Maintain a minimum clearance of 20 mm above and below the unit to facilitate natural convection cooling.
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.
