Installation

Safety measures before installation
This equipment is to be protected against improper use. Components are not to be bent or isolation spacing changed, especially through handling and transport. The contact with electrical components and terminals is to be avoided. Always disconnect the equipment from the mains supply, before commencing installation or wiring. The product description, technical information in our main catalogue and the marking on the equipment ratings plate are to be observed.

Installation
Installation must be carried out according to the prevailing local conditions and safety regulations (e.g. VDE 0100) national accident prevention regulations (e.g. UVV-VBG4 or BGV A3) and the generally accepted rules of technology. This equipment is a component designed for installation into electrical systems and machines, and fulfils the requirements of the low voltage guidelines (2014/35/EU).

The required minimum spacing to neighbouring components must be observed to guarantee the required cooling. When installed into machinery, the normal operation is forbidden until it is determined that the machine fulfils the requirements of the machinery guidelines (2006/42/EG). EN 60204 must be observed. The EMC requirements (2014/30/EU) must be fulfilled before operation is commenced. The observance of the required limitations for the EMC legislation is the responsibility of the manufacturer of the installation or machinery.

Terminals handling

1 LED: The green LED lights as soon as the output voltage is present.
2 Input
3 Output
4 Mounting: Place the device with the DIN rail guide on the upper edge of the DIN rail, and snap it in with a downward motion.
5 Removing: Pull the snap lever open with the aid of a screwdriver and slide the device out at the lower edge of the DIN rail.
