1 Preliminary note
This document applies to the DF11xx supply modules and the DF12xx 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.

To disconnect press the orange pusher using a suitable tool.
To open the push-in terminals IO-Link use a 2 mm wide micro screwdriver.
As soon as the supply module is supplied with voltage, the device closes
the contacts connected to terminals 13 and 14. If a fault occurs at min. one
of the connected channels, the device opens the contacts again.
