UNO-PS/1AC/ 5DC/ 40W 7.3 Mounting on a DIN rail The power supply unit can be installed on all 35 mm DIN rails according to EN 60175. A Figure 3 7.4 B Mounting on a DIN rail Normal mounting position When installed, the input terminal blocks must be at the bottom and the output terminal blocks at the top. If the power supply unit is installed in a mounting position other than the normal mounting position, the output power must be reduced.
UNO-PS/1AC/ 5DC/ 40W 8 Installing the power supply unit 8.1 Safety regulations and installation notes WARNING: risk of electric shock! Only qualified specialist personnel may install, start up, and operate the device. Observe the national safety and accident prevention regulations. 8.2 The device can be connected to single-phase AC or threephase power grids (TN-S, TN-C, TT, and IT) while considering the nominal input voltage.
UNO-PS/1AC/ 5DC/ 40W 8.3 Device connections 8.4 Connecting cables Screw connection for input AC L/N Figure 6 Use copper cables with an operating temperature > 75°C (ambient temperature < 55°C) and > 90°C (ambient temperature < 75°C). Screw connection for input AC L/N Screw connection for output DC +/- Figure 8 1. Figure 7 Screw connection for output DC +/- 2. Connecting cables Connect the supply lines to the input AC L/N connection terminal blocks.
UNO-PS/1AC/ 5DC/ 40W 9 Operating behavior of the power supply unit 9.1 Normal operation In normal operation, the loads are supplied with a constant output voltage of 5 V DC. 9.2 Overload response [V] In the event of overload (I > IN), the device reduces its output voltage. If the output voltage is greater than UN x 0.9, the green DC OK LED lights up. If the output voltage drops below UN x 0.5, the device shuts down. After a short time, the device attempts to start up again.
UNO-PS/1AC/ 5DC/ 40W 9.4 Behavior in the case of alternative mounting positions For mounting positions that differ from the normal mounting position, the output power must be reduced (position-dependent derating). The characteristic curve can be used to determine the maximum output power to be drawn for each ambient temperature for different mounting positions.

UNO-PS/1AC/ 5DC/ 40W 10.2 Operating power supply units in parallel Power supply units of the same type can be connected in parallel to increase both redundancy and power. To ensure symmetrical current distribution, all cable connections from the power supply unit to the busbar must be the same length and have the same conductor cross section. Redundant operation Redundant circuits are suitable for supplying systems which place particularly high demands on operational safety.
UNO-PS/1AC/ 5DC/ 40W 10.3 Operating the power supply unit in series Two devices can be connected in series to double the voltage. Only power supply units of the same type should be connected in series. Series connection should always be used when the output voltage of the module is not sufficient. For example, devices with 24 V DC nominal output voltage each supply 48 V DC in series.
