Installation Guidelines
Ensure the power supply is mounted on a standard 35mm DIN rail.
Maintain adequate clearance around the module to allow for proper convection cooling and heat dissipation.
Always disconnect the main AC power source before installing or removing the module to prevent electrical shock or damage to the backplane.
Use appropriate wire gauges for the input and output terminals to ensure secure connections and minimize voltage drop.
Verify that the input voltage selector or auto-ranging configuration matches your local supply voltage before energizing.
Ensure proper grounding of the power supply chassis to the control cabinet's protective earth (PE) bus.
FAQ
Is the 6ES7307-1KA00-0AA0 still in production?
