Installation Guidelines
- Ensure the power supply is disconnected from the AC source before performing any wiring or installation.
- Mount the module in a well-ventilated area to allow for natural convection cooling; maintain adequate clearance around the enclosure.
- Use appropriate wire gauges for input and output connections to prevent voltage drop and overheating.
- Ensure a solid chassis ground connection to the metal enclosure to maintain EMI/EMC compliance.
- Verify that the input voltage matches the module's rated range (100-240V AC) before energizing.
- Handle with care to avoid damage to the conformal coating; observe standard ESD precautions when handling the module.
FAQs
