Only remove equipment when it is disconnected and not in the potentially explosive area. DANGER The device contains dangerous live elements and high levels of stored energy. Never carry out work when the power is turned on. WARNING: Before startup please ensure: The mains connection has been carried out by a competent person and protection against electric shock is guaranteed! The device can be disconnected outside the power supply unit in accordance with the regulations as in EN 60950 (e.g. through primary side line protection)! All feed lines are sufficiently protected and dimensioned! All output lines are dimensioned according to the maximum output current of the device or separately protected! Sufficient convection must be guaranteed. CAUTION: The power supply units are built-in devices. The device may only be installed and put into operation by qualified personnel. The corresponding national regulations must be observed. 106206_en_00 PHOENIX CONTACT 8 Produktbezeichnung 8 Installation NOTE: In order to ensure sufficient convection, we recommend a minimum vertical distance of 30 mm to the other devices. The power supply unit can be snapped onto all DIN rails as per EN 60715; it can also be mounted on walls. The device must be mounted vertically (connecting terminals above or below). 9 Mounting position 18 55 30 150 90 45 30 44 50 61 106206_en_00 PHOENIX CONTACT 9 Produktbezeichnung 10 Mounting on DIN rails Assembly To mount on an EN DIN rail, snap the device straight onto the DIN rail. If the power supply unit is to be fastened directly onto an even surface, press the orange base latch upward and down. Place a washer between the pulled-out base latch and the even surface (max. outer diameter 8.5 mm, max. thickness 1.3 mm, e.g., spring washer for M4 in acc. with DIN 127-B or toothed lock washer in acc. with DIN 6797). Then fasten the device with two screws (max. thread diameter 4 mm, max. head diameter 8.5 mm). Removing To dismantle from the EN DIN rail, press the orange base latch outward and pull the device off of the DIN rail. In the case of wall mounting, loosen the screws and press the base latch inwards again. 11 Input CAUTION: If an internal fuse is triggered, there is a device malfunction. In this case, the device must be inspected in the factory. Protection of the primary side 43-52 V The device must be installed in acc. with the regulations as in EN 60950. It must be possible to disconnect the device using a suitable isolating facility outside the power supply. The primary side line protection, for example, is suitable. For device protection, there is an internal fuse. Additional device protection is not necessary. Permissible backup fuse for mains protection Power circuit-breaker 6 A, 10 A or 16 A, characteristic B (or identical function). 106206_en_00 PHOENIX CONTACT 10 Produktbezeichnung 12 Output CAUTION: Make sure that all output lines are dimensioned according to the maximum output current or are separately protected. The cables on the secondary side must have sufficiently large cross sections in order to keep the voltage drops on the lines as low as possible. The connection is made using the "+" and "-" screw connections on the screw connection of the DC output. The set output voltage is 24 V DC at the time of delivery. Protection of the secondary side The device is electronically protected against short-circuit and idling. In the event of a malfunction, the output voltage is limited to 35 V DC. 13 Signaling The "DC OK" LED enables evaluation of the function of the power supply directly on site.
