1  Preliminary note

This document applies to the DF21xx supply modules and the DF22xx circuit 

protection modules.
Read this document before use to familiarise yourself with operating conditions, 

installation and operation. Keep this document during the entire duration of use of 

the device.

WARNING

Adhere to the warning notes and safety instructions (→ 2 Safety instructions).

The devices are not suitable for battery-backed applications.

2  Safety instructions

•  The devices are intended for use with a 24 V DC safety extra-low voltage.

•  A wrong connection to voltage which is higher and/or not safely isolated may 

lead to damage or conditions which are dangerous to life.

•  Use the supply module only with the matching circuit protection modules.

•  Observe the technical data of the circuit protection modules used.

•  The devices must be installed, connected and put into operation by a qualified 

electrician.

•  Adhere to the national regulations regarding the installation and selection of 

cables.

•  Do not mount the devices and do not actuate the contact levers while live.

•  Supply the devices with energy only after they have been properly installed.

•  After triggering a circuit protection module and before power on again, remove 

the cause of triggering (short circuit or overload).

•  Check the devices for damage prior to installation. Faulty devices must not be 

used.

•  In case of malfunction of the unit or queries, please contact the manufacturer. 

Any tampering with the device can seriously affect the safety of operators and 

machinery.This is not permitted and leads to the exclusion of any liability and 
warranty claims.
