Notes on these operating instructions
Instruction Obligation These operating instructions must be read carefully by all persons working with or on the switch mode power supply prior to installation and initial start-up. These operating instructions are a composite part of the switch mode power supply. [. . . ] Connect the load/battery Set the UA output voltage to the required value with the UA potentiometer. The maximum output current is also adjustable within a limited range with the IA potentiometer.
-
Procedure: Increase the load until the set current limitation is triggered Adjust the IA potentiometer with a screwdriver (IA smaller when turned to the left).

Monitoring Mains Monitoring
The mains monitoring assembly fulfils various functions. It ensures the intrinsic safety of the unit against overloads and overvoltages with fixed switching point settings. The response values (switching points) are given in the technical data sheet.

Mains undervoltage monitoring The unit is switched off if the mains supply drops below the switching point. When the hysteresis voltage is exceeded the unit automatically resumes operation with a "soft start".

Mains overvoltage monitoring When the maximum permissible mains voltage is exceeded, the SMPS is stopped for the duration of the overvoltage. When the voltage level drops below the hysteresis voltage the unit automatically resumes operation with a "soft start".

Output Monitoring
The setting potentiometers and the LED indicators for the following monitored functions are located on the front plate: Overtemperature monitoring AC 2000 with deactivation, without latching. When the unit has cooled down it automatically resumes operation with a "soft start". Fault, with deactivation and latching - DC overvoltage indicator UA>

5. 3. 3
Reset Buttons/Functions
A fault signal (response of an output monitoring device) can be acknowledged with the "Reset" button. A fault signal can also be acknowledged by switching off the mains voltage or with the external on/off function.
5. 3. 4
Signalling
The faults are indicated by LEDs on the front panel and signalled on signal connector X11 as a collective signal via a potential-free relay contact (changeover contact) (refer to circuit diagram). The contact between X11:12 and X11:13 is closed in the event of unit failure. Relay contact load: Umax = 110 V DC Iper < 0. 45 A DC Umax = 60 V DC Iper < 1 A DC Umax = 24 V DC Iper < 8 A DC Maximum isolation from the secondary side: 110 V DC

Parallel Operation
Due to the inclination of the voltage step of approximately 1% a load distribution of approximately 10% is achieved in parallel operation of several SMPS units. If load distribution is to be optimized the output voltage of the unit with the lowest load current should be increased and the output voltage of the unit with the highest load current decreased. Selective monitoring of the individual SMPS units is only possible with external isolating diodes in the output. Systems with redundancy As the units can be connected in parallel it is possible to create systems for redundant operation in accordance with the n+1 principle.
7.
Separate Networks
When the SMPS is connected to separate networks, mains overvoltages must be expected which can last for a period of seconds. For example if rotary converters are used for supply, up to 20% overvoltage over a period of seconds occurs. The mains overvoltage monitoring device (refer to 5. 3. 1) stops the unit for the duration of the overvoltage.

Signal Interface (X11)
External On/Off
The unit can be switched on and off externally via a potential-free contact (contact load 15 V DC/5mA, contact open = "Unit Stop"). To this purpose the bridge on signal connectors X11:7 and X11:8 must be removed and a relay contact looped in (refer to Chapter 5. 1). In the case of positive pole earthing the potential - UA which is now higher (in relation to reference potential) is applied to these inputs. Electrical isolation must therefore be carried out by the external relay.
8. 2
External Sensor Lead Output Voltage UA
On all units is possible to compensate a voltage drop of 1 V on both the positive and negative output cables. For compensation on the positive output cable X11:9 is connected to the positive pole of the load, for compensation on the negative output cable X11:10 is connected to the negative pole of the load. [. . . ] In the case of an external set value input, is the set value correct?
