7.3 Mounting on a DIN rail
The power supply unit can be installed on all 35 mm DIN rails according to EN 60175. Figure 3 Mounting on a DIN rail
7.4 Normal mounting position
When installed, the input terminal blocks must be at the bot- tom 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. Figure 4 Normal mounting position AB

8 Installing the power supply unit
8.1 Safety regulations and installation notes 8.2 Mains connection The device can be connected to single-phase AC or three- phase power grids (TN-S, TN-C, TT, and IT) while consider- ing the nominal input voltage. Figure 5 Network types WARNING: risk of electric shock! Only qualified specialist personnel may in- stall, start up, and operate the device. Ob- serve the national safety and accident prevention regulations. Prior to installation, disconnect the input volt- age and make sure that it cannot be switched on again unintentionally. Mains connection must be performed by spe- cialist personnel and protection against elec- tric shock ensured. Make sure that the device can be switched off outside the power supply according to the regulations in EN 60950 (e.g., by line protec- tion on the primary side). Cover termination area after installation in or- der to avoid accidental contact with live parts (e.g., by installing in a control cabinet). Protect the device against ingress by foreign bodies, e.g., paper clips or metal parts. WARNING: Make sure that all supply lines are sufficiently dimensioned and have sufficient fuse protec- tion. Make sure that all output cables are dimen- sioned accordingly for the maximum device output current or have separate fuse protec- tion. NOTE: Never open or repair the device yourself. Internal fuses will only blow in the event of de- vice malfunction. Do not modify or attempt to repair the device. Send the device to the fac- tory for examination. For operation on two of the phase conductors of a three-phase system, an isolating facility for all poles must be provided. TN-S TN-C L N PE LN L PEN LN TT iT LN L N L N

8.4 Connecting cables
Figure 8 Connecting cables 1. Connect the supply lines to the input AC L/N connection terminal blocks. 2. Connect the output cables to the output DC +/- connec- tion terminal blocks. The power supply unit is operational as soon as the input ter- minal blocks are supplied with voltage. Use copper cables with an operating temper- ature > 75°C (ambient temperature < 55°C) and > 90°C (ambient temperature < 75°C).

9 Operating behavior of the power
9.1 Normal operation
In normal operation, the loads are supplied with a constant output voltage of 24 V DC.
9.2 Overload response
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 U N x 0.5, the device shuts down. After a short time, the device attempts to start up again. If the overload has been rectified, it will start up as normal. If the overload has still not been rectified, it will shut down again and attempt to restart again (automatic restart). Figure 9 Output characteristic curve
9.3 Behavior at ambient temperatures > 55°C
At an ambient temperature of up to 55°C, the power supply unit supplies the nominal output current. At ambient temper- atures upwards of 55°C, the output power must be reduced by 2.5% per Kelvin temperature increase (temperature-de- pendent derating).

9.4 Behavior in the case of alternative mounting
For mounting positions that differ from the normal mounting position, the output power must be reduced (position-de- pendent derating). The characteristic curve can be used to determine the max- imum output power to be drawn for each ambient tempera- ture for different mounting positions.

10 Operating the power supply unit
10.1 Function monitoring
The DC OK LED is available for visual function monitoring of the power supply unit. Status 1 Status 2 DC OK LED Lit OFF Meaning Output voltage > 21.5 V Output voltage < 21.5 V DC, overload mode or no mains voltage State description The device is operating, output voltage and output current are OK The device is in operation, but there is a fault on the side of the consumer; the current consumption is greater than IN or the output is short-circuited. The device is out of operation because there is no mains voltage, the fuse on the primary side has been triggered, or the device is faulty. Remedy Remove the error at the load, use a more powerful power supply unit, connect a power supply unit of the same type parallel to the existing device, remove the short circuit, apply mains voltage, enable the fuse again or replace the power supply unit.

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. Redundant operation Redundant circuits are suitable for supplying systems which place particularly high demands on operational safety. If a fault occurs in the primary circuit of the first power supply unit, the second device automatically takes over the com- plete power supply without interruption, and vice versa. Using a redundancy module, it is possible for two power supply units of the same type that are connected in parallel on the output side for redundancy to be decoupled from one another. Figure 11 Redundant circuit with redundancy module Increased performance Power supply units of the same type can be connected in parallel to increase the power to n x I N. Parallel connection is recommended if existing systems are to be extended and the power supply unit that is installed here does not cover the current consumption of the most powerful load. Other- wise, the loads should be distributed between individual de- vices that are independent of one another. Using a redundancy module, it is possible for two power supply units of the same type that are connected in parallel on the output side to increase power to be decoupled from one another. Figure 12 Parallel connection to increase power with a redundancy module 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. IN − + IN Σ = IN IN − + IN − Σ =2xI N

10.3 Operating the power supply unit in series
Two devices can be connected in series to double the volt- age. 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. Depending on the specifica- tion of functional earth ground, output voltages of + 48 V/- 48 V as well as ±24 V DC can also be made available. Figure 13 Series operation
