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
