PWM KN series can be ETS adressing/programming WITHOUT connecting to AC mains 

## ◎ **Cautions** 

Before commencing any installation or maintenance work, please disconnect the power supply from the utility. Ensure that it cannot be re-connected inadvertently! 

Keep proper ventilation around the unit and do not stack any object on it. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source. 

Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. 

Current rating of an approved primary /secondary cable should be greater than or equal to that of the unit. Please refer to its specification. 

Tc max. is identified on the product label. Please make sure that temperature of Tc point will not exceed limit. DO NOT connect "KNX- to Vo-". 

The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. 

For more information about installation, Please refer to : http://www.meanwell.com/manual.html for details.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
