## **1. General** ~~a~~ 

**Proper handling of the product** The faultless and safe operation of the products requires proper transport, proper storage, set-up, assembly, installation, commissioning, operation and maintenance. The permissible ambient conditions must be observed. Instructions in the associated documentation must be observed. 

## **Protection enclosure required** 

The device must be installed in a protective housing or control cabinet to which only qualified personnel have access. 

## **Humid environments** 

Do not operate the device in a damp environment or in an environment where condensation is likely to occur. 

## **Switch or circuit-breaker mounting position** 

A switch or circuit-breaker must be mounted near the equipment. 

## **Observe country-specific regulations** 

In addition to the product documentation, the relevant country-specific regulations for the installation of the device must be observed. 

## **Prohibited electrical/mechanical modifications** 

The product must not be modified in any way electrically or mechanically. Modifications can result in fatal injuries and damage to property. 

## **Expiry of the manufacturer’s warranty** 

The power supply is maintenance-free. Repairs can only be carried out by the manufacturer. Opening the housing voids the manufacturer’s warranty. 

## **Use of third-party products** 

If third-party products and components are used for power or voltage increase, buffering (primary or secondary side), EMC filtering, redundancy 

or for load protection, it must be approved by TDK-Lambda.

**7. Reliability and Service lifetime** ~~Lo~~ 

The service lifetime of the power supply is determined primarily by the electrolytic capacitors utilised. The values provided herein are calculated estimates, and as such, do not represent guaranteed lifetimes. The calculation is based on the respective capacitor manufacturer’s method, taking into account ripple current, operating frequency, and capacitor temperature under the herein specified operating conditions. It is important to note that, due to the theoretical nature of the calculation, all capacitor manufacturers specify a maximum expected service lifetime of 15 years. 

TDK-Lambda applies strict component selection criteria and utilises electrolytic capacitors exclusively from reputable manufacturers such as Murata, Nippon Chemi-Con, Nichicon, Rubycon, and TDK.

~~a~~ **14.4 HIPOT test** Apart from routine and type test, the end user might need to check the insulation strength during the final inspection and testing to guarantee the electrical safety of the end application. Therefore, a high-voltage test (HIPOT test) can be performed in the field. The following conditions must be observed: 

- As every HIPOT test causes stress on the power supplies safety insulation, avoid frequent HIPOT testing or excessive test voltages 

- The test voltages and durations, as indicated under „14.2 Insulation strength“ on page 18, must not be exceeded 

► The test voltages rise and fall time should be between 2 and 4 seconds 

- According to EN 60204-1 (Safety of machinery - Electrical equipment of machines), an individual HIPOT test of the power supply isn't 

- ~~@~~ required. During the HIPOT test of the end application, the power supply can be disconnected and only installed once the test has been completed. 

Unless otherwise stated, all values are specified in normal mounting position, at full load, nominal input and output voltages, 25°C (77°F) ambient temperature and a run-in time of 5 minutes.

Conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA). 

UKCA (UK Conformity Assessed) is the product marking that is used for certain goods being placed on the United Kingdom market. 

The Waste Electrical and Electronic Equipment Directive (WEEE Directive) is the European Community Directive 2012/19/EU on collection, recycling and recovery targets for all types of electrical goods. 

The Restriction of Hazardous Substances Directive 2011/65/EU (RoHS 2) regulates the use of certain hazardous substances in electrical and electronic equipment. 

Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation that addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. 

## **20. Application notes** 

## ~~LLL~~ **20.1 Parallel operation** 

The power supplies do not offer a parallel mode for load sharing. Paralleling power supplies to increase power is not recommended. 

A 1+1 redundant system can be built by connecting the power supplies in parallel using a decoupling module. The products in the TDK-Lambda DRM series are recommended for this purpose. (refer to chapter "Add-ons and accessories" on page 3) 

The following measures must be taken into account when setting up a 1+1 redundant system: 

- Only power supplies of the same series and power rating must be paralleled 

- Load wiring shall be identical in terms of length and cross section 

- The output voltage of the power supplies must be set to the same value 

- The output voltage of each power supply should be checked and maintained in regular intervals 

- All power supplies must be operated under the same ambient conditions 

- The power supplies must not be operated under any condition which requires a power derating (e.g. altitudes above 3000mASL 

   - (9842ftASL), temperatures above 55°Camb (131°Famb), mounting orientations others than the normal mounting position, etc.) 

- The increased installation distances must be taken into account when installing the power supplies side by side (see "Installation clearances" on page 15) 

   - In parallel operations the values of output load regulation, inrush currents, EMI, harmonic and leakage currents will increase.

## ~~LL~~ **20.2 Series operation** 

In order to increase the output voltage, it is possible to connect the power supplies in series.  The following measures must be taken into account: 

- The output voltage sum must not exceed 250VDC 

- If the output voltage sum exceeds 60VDC, a safeguard against unintended touching must be considered 

- Only power supplies of the same series and power rating must be connected in series 

- All power supplies in series must be operated under the same ambient conditions 

- The power supplies must not be operated under any condition which requires a power derating (e.g. altitudes above 3000mASL (9842ftASL), temperatures above 55°Camb (131°Famb), mounting orientations others than the normal mounting position, etc.) 

- The increased installation clearances must be considered (refer to chapter "Installation clearances" on page 15) 

In series operations the values of output load regulation, inrush currents, EMI, harmonic and leakage currents will increase.
