SAFETY & EMC 

INDUSTRIAL & AUTOMATION BUILDING & HOMEAUTOMATION ENERGY DATACOM & TELECOM INFRASTRUCTURE ~~|~~ MY ~~\CO~~ | | ~~amu~~ . DESCRIPTION ~~|~~ 

The slim RACPRO1-T240 is a high reliability, three phase AC input, 24V/240W DIN rail mount power supply in extremely compact dimensions of 135 x 125mm with a width of only 43mm. It is specially designed for demanding applications in the harsh industrial automation field with an extended mains input surge immunity of up to 6kVAC and return voltage immunity >35V at the output making it suitable for safe operation against back feeding loads like decelerating motors and inductors. These units will deliver up to 240W over the full -40°C to +60°C ambient temperature range with only convection cooling. An Thermal Power Bonus of up to 288W at 45°C plus a power boost of up to 150% for 5s makes them suitable for powering highly inductive or capacitive loads. The unique and innovative modern design with 25° push-in connectors allows easy tool-less installation or replacement. The product is certified according to the global safety standards IEC/EN/UL 62368-1, IEC/EN/UL 61010-1 and IEC/EN/UL/CSA 61010-2-201. Electromagnetic radiated and conducted emissions are compliant to heavy industrial EN 61000-6-4 Class B emission standard and EN 61000-6-2 immunity standard.

1. Place the device on the DIN rail with a slight upward tilt. Snap the device into the DIN rail. 

2.  Now tilt the device downwards until it reaches the lower part of the DIN rail. 

3.  Press the lower part of the device firmly against the rail until the device locks into position on the DIN rail. 

4. To make sure it is securely locked in place, give the device a gentle shake.

1. Press the unlock button on the top of the device to release the latch from the rail. 

2. While pushing the button, slightly tilt the device forward. 

3. Pull the device away from the DIN rail by pushing it up 

4. Remove the power supply completely from the rail.

## INSTALLATION & APPLICATION 

## Installation Instructions 

To ensure sufficient convection cooling, keep a distance of 20mm above and 40mm below the device. For vertical installation, the device must be installed with the input terminal facing downwards. A gap between the units is not required.

0mm<br>20mm<br>40mm<br>**----- End of picture text -----**<br>


## Parallel operation to increase power rating 

- 1) Adjust each power supply to the exact same output voltage with same load and cooling conditions. 

- 2)  Use the same wire length and cable cross-section for each power supply (star connection) and energize all units at the same time to avoid triggering overload protection. 

- 3) Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation (input terminals on the bottom of the unit) or in any other condition where a derating of the output current is required (e.g. above 60°C, …). 

- 4) Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
