DANGER Components with dangerously high voltage and high stored energy are located in the device! Never carry out work on live parts! Depending on the ambient temperature and the load, the housing can become very hot! 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)! The ground conductor is connected! 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 is guaranteed! ATTENTION 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. 103131_en_01 PHOENIX CONTACT 7

8 Installation ATTENTION In order to ensure sufficient convection, we recommend a minimum vertical distance of 50 m to the other modules. A lateral distance of 5 mm, and in the case of active components, that of 15 mm is necessary for proper functioning of the module. Depending on the ambient temperature and the load of the module, the housing can become very hot! 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 Installation position 5 60 5 122 230 130 115 50 Slim-style installation: Installation depth 125 mm ( DIN rail) (state at delivery) Low-profile installation: Installation depth 63 mm ( DIN rail) 103131_en_01 PHOENIX CONTACT 8

10 Mounting on DIN rails A B Slim-style installation Assembly: Position the module with the DIN rail guide on the upper edge of the DIN rail, and snap it in with a downward motion. Removing: Pull the snap lever open with the aid of a screwdriver and slide the module out at the lower edge of the DIN rail. A B Low-profile installation Low-profile installation can be achieved by mounting the device at right-angles to the DIN rail. Mount the DIN rail adapter (UTA 107/30) as described in the figure. No additional mounting material is required. Fixing screws: Torx T10 (torque 0.8 Nm... 0.9 Nm). 103131_en_01 PHOENIX CONTACT 9

The device can be connected to 3-phase systems with nominal voltages 3x 400 V AC... 500 V AC are connected. In the event of a phase failure, unrestricted operation is possible with nominal capacity. An operation in DC networks is also possible without any limitations. ATTENTION In DC applications, a suitable fuse must be wired upstream! Connect not more than one power supply unit to a fuse or a power switch. Suggestion: In AC connections, connect a maximum of one power supply unit to a fuse or a power switch. In order to comply with UL approval, use copper cables with an operating temperature of > 75 C (ambient temperature < 55 C) and > 90 C (ambient temperature < 75 C). 12 Input ATTENTION If an external fuse is triggered, there is most probably a malfunction in the device. In this case, the device must be inspected in the factory! Protection of the primary side 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. Primary circuit mains protection, for example, is suitable for this purpose. Required backup fuse (device and line protection) External thermo-magnetic fuses are necessary for device protection: 2/3 x 6 A, 10 A or 16 A power circuit breaker, characteristic B (or identical function). Connect a suitable fuse upstream for DC applications! 103131_en_01 PHOENIX CONTACT 10

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 established using screw connections on the screw connection of the DC output: 24 V DC: "" and " "; switching output active: "" and " "; output floating: "13" and "14"; POWER BOOST switching output active: "I < I N " and " ". At the time of delivery, the output voltage is 24 V DC. The output voltage can be set on the potentiometer. Protection of the secondary side Input AC 100-240 V L N PE 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. 14 Signaling An active signal output, a floating signal contact and an active signal output POWER BOOST are available for function monitoring. In addition, the LED and the BOOST LED can be used to evaluate the function of the power supply directly at the installation location (see output characteristic curve).

13 14 Output 24 V DC - - - Floating contact The floating signal contact opens and indicates that the set output voltage has undershot by more than 10%. Signals and ohmic loads of up to maximum 30 V and currents of maximum 1 A (or maximum 60 V with maximum 0.5 A) can be switched. For heavily inductive loads such as a relay, a suitable protection circuit (e.g. damping diode) is necessary. max. 30 V AC/DC 1A Active signal outputs 13 14 18... 24 VDC 20 ma Output 24 VDC - - - The 18... 24 V DC signal is applied between the "" and the " " connection terminal blocks or between "I < I N " and " " and can carry up to 20 ma. By switching from "active high" to "low", the signal output signalizes when the output voltage is fallen short of by more than 10 %. The signal is decoupled from the power output. This ensures that an external supply does not enter from devices connected in parallel. The POWER BOOST signal output I < I N signalizes that the nominal current is exceeded. The power supply unit is then in the POWER BOOST mode. Using this preventive function monitoring, critical operating statuses can be governed at an early stage before it results in a voltage dip. The 18... 24 V DC signal can be directly connected to a logic input for evaluation. 1 2 13 14 Output 24 V DC - - - 13 14 Output 24 V DC - - - Signal loop Monitoring two devices: Use the active signal output of device 1 and loop in the floating signal output of device 2. In the event of malfunctioning, a common alarm is output. Any number of devices can be looped in. This signal combination saves wiring costs and logic inputs. 103131_en_01 PHOENIX CONTACT 12

15 Function Output characteristic curve The power supply unit works with the static power reserve POWER BOOST as shown in the U/I characteristic curve in the figure. At ambient temperatures T amb <40 C, I BOOST is available continuously. At higher temperatures, it's available for a few minutes. In the event of a secondary-side short circuit or overload, the output current is limited to I BOOST. Thereby, the module does not switch off, but rather supplies a continuous output current. The secondary voltage is reduced here until the short circuit is eliminated. The U/I characteristic curve with the power reserve POWER BOOST ensures that both high inrush currents of capacitive loads as well as consumers with DC/DC converters in the primary circuit can be supplied. In order to trip standard power circuit breakers magnetically and very quickly, power supply units must supply a multiple of their nominal current for a short period. As can be seen from the characteristic curve, when I < I N, I > I N and U < 0.9 x U N. The relevant signaling can be found in the table "Signaling". U N = 24 V I N = 10 A I BOOST = 15 A SFB technology = 60 A P N = 240 W P BOOST = 360 W U [V] OUT U N I<I N I N I>I N U<0,9xU N I BOOST I OUT [A] Thermal behavior Output current [A] I BOOST I N 0-25 20 40 60 Ambient temperature [ C] With an ambient temperature of up to 40 C, the device supplies the continuous output current of I BOOST. The device can supply a nominal output current of I N with ambient temperatures of up to 60 C. In the case of ambient temperatures above 60 C, the output current must be reduced by 2.5% per Kelvin increase in temperature. The device does not switch off at ambient temperatures of 70 C or thermal overload. The output capacity is reduced as far as necessary to provide device protection. After it has cooled down, the output capacity is increased again. 103131_en_01 PHOENIX CONTACT 13

Parallel operation Devices of the same type can be connected in parallel to enable both redundancy and an increase in efficiency. On default upon delivery, a further adjustment is not needed. If the output voltage is adjusted, a uniform distribution of power is guaranteed by setting all parallel operated power supply units to exactly the same output voltage. To ensure symmetrical current distribution we recommend that all cable connections from the power supply unit to the busbar are the same length and have the same cross-section! Depending on the system, for parallel connection of more than two power supply units a protective circuit should be installed at each individual device output (e.g. decoupling diode, DC fuse or power circuit breaker). This prevents high return currents in the event of a secondary device fault. Redundant operation I N I N Σ =I N Redundant circuits are suitable for the supply of systems which make especially high requirements on the operational safety. If a fault occurs in the primary circuit of the first power supply unit, the second device automatically takes over the entire power supply, without interruption, and vice versa. For this reason, the power supply units to be connected in parallel are dimensioned in such a way that the total current requirement of all consumers can be completely covered by one power supply unit. 100% redundancy makes external decoupling diodes necessary (QUINT-DIODE/40, Order No. 2938963)! I N I N Increased performance For n parallel connected devices, the output current can be increased to n x I N. Parallel connection for increasing power is used when extending existing systems. A parallel connection is recommended if the power supply unit does not cover the current consumption of the most powerful load. Otherwise the loads should be divided on individual devices independent from each other. Σ =2xI N 103131_en_01 PHOENIX CONTACT GmbH & Co.
