1.2 Mounting the PS 1000/230 010 and 011 in the M 3421 Subrack The equipment depends on the wiring of the M 3421 subrack. Slots not in use can be fitted with the M 4413 dummy front plate (part no. 60 5240002). Maintain a distance of 30 mm to the front of the power supply fan. 1.2.1 ESD Protective Measures Only personnel with knowledge of ESD protective measures may install and remove a power supply unit. An electrostatic discharge can damage the electronic components within the systems. Touch a grounded object to discharge any static in your body. When performing the work, make sure that the workspace is free of static, and wear an ESD wrist strap. If not used, ensure that the module is protected from electrostatic discharge, e.g., by storing it in its packaging. 1.2.2 Mounting the Power Supply Unit A Phillips screwdriver PH1 is required for mounting the power supply unit. 1. Check the mechanical coding on the subrack. 2. In the off-state, insert the power supply unit completely in the subrack. 3. Use the four captive screws to secure the power supply unit to the subrack housing. 4. The M 4413 dummy plates can be secured to the slots not in use. Please check the correct coding on the subrack before inserting the power supply unit. Inserting a 48-V instead of a 24-V power supply unit causes the destruction of electronic components. 1.2.3 Removing the Power Supply Unit A Phillips screwdriver PH1 is required for removing the power supply unit. 1. Use the overcurrent circuit breaker to switch off the power supply unit. 2. Release the four captive screws on the subrack. 3. Remove the power supply unit from the subrack. 5 of 12
1.3 Product Description Figure 4: PS 1000/230 24 VDC Front View and Rear View Figure 5: PS 1000/230 24 VDC Side View The PS 1000/230 010 and 011 variants are modular cartridges for use in the 19'' subrack M 3421, with 4 RU high, see M 3421 data sheet. The M 3421 subrack is designed for up to three power supply units and is used for the HIMA PS 1000 series of power supply units. This variant is mechanically coded to ensure that only the correct power supply unit type can be inserted into the subrack, see Chapter 1.6.2. The PS 1000/230 016 and 017 variants are secured to a backplane (e.g., mounting plate), see Chapter 1.1. The power supply unit supplies a 24 VDC output voltage to the L+/L- or R+/L- terminals with a nominal current of 40 A (short-circuit-proof) and bridges voltage drop outs of 20 ms. For redundant operation, the power supply units can be connected in parallel via the decoupled R+ terminals, see Chapter 1.6. 6 of 12
The power supply unit is equipped with a fan on the front side. If the fan fails, the fault relay trips, see Chapter 1.5. The fault relay's contact is lead through to the rear side of the power supply unit. Two LEDs on the front plate indicate that the power supply is operating properly. The green LED RUN is lit if sufficient output voltage is available. The red LED ERR is lit if fan speed is too low, the fan is idle or if the output voltage is too low. A ΔU potentiometer is located on the front side for adjusting the voltage, see Chapter 1.7. 1.3.1 Standards The power supply unit's output voltage meets the requirements for SELV- and/or PELV circuits. PS 1000/230 01 CE IEC 61131-2: 2007 IEC 61000-6-2: 2005 IEC 61000-6-4: 2007 IEC 60079-15: 2005 EMC Directive EX Directive Low Voltage Directive BUREAU VERITAS Table 3: Standards 2004/108/EC ATEX 94/9/EC, for variants PS1000/ 230 011 and 017 2006/95/EC Rules for the Classification of Steel Ships 1.4 Block Diagram Figure 6: Block Diagram 7 of 12
1.5 Function of the Fault Relay The fault relay's contact can be used to connect optical and acoustic detectors with a current input of up to 1 A, see Chapter 1.8. The fault relay is activated during normal operation and trips if the following faults occur: The fan speed is too low. The fan is blocked. The output voltage is too low. The temperature is too high. The power supply unit is defective. The following table describes the statuses of the fault relay contacts: Contact (Fail) C-NC closed (C-NO open) C-NC open (C-NO closed) State Relay energized, normal function Relay de-energized, fault within the power supply unit Table 4: Fault Relay States 8 of 12
1.6 Operation The power supply unit must be switched on and off using the thermal overcurrent circuit breaker located on the front side. To switch on, press the overcurrent circuit breaker until it is engaged. To ensure the soft start electronics can regulate the power-on current, wait at least 1 minute after switching the power supply unit off and before switching it on again. All connections are established using separated female connectors located on the back of the power supply unit. The decoupled R+ terminal must be used when multiple power supply units are connected in parallel to increase power or implement redundancy. 1.6.1 Operating Multiple Power Supply Units in the M 3421 Subrack All connections for the power supply units are established using separated female connectors located on the back of the subrack, see Figure 8. With redundant power supply units, a unit can be replaced during operation. Prior to removing the power supply unit, it must be switched off using the overcurrent circuit breaker located on the front side.

1.6.2 Mechanical Coding The variants for the M 3421 19" subrack are mechanically coded on the rear side. The coding is performed with up to 4 coding pins and the corresponding coding screws are screwed in to the rear side of the M 3421 subrack. The Variants PS 1000/230 010 and 011 are not coded. To prevent the use of coded power supply units, screw all coding screws delivered with the PS 1000/230 010 and 011 in to the M 3421 subrack, see Figure 9. Figure 9: Securing the Coding Screws on the M 3421 Subrack 1.7 Adjustment of Power Supply Units Connected in Parallel The output voltage for the power supply units is preset in the factory to 24.2 V ± 10 mv with 40 A load on L+. Decoupling reduces the output voltage on R+ by the amount of voltage drop, see Chapter 1.8. To avoid load differences during parallel operation, connect cables of the same length to R+. The power supply units are adjusted to other voltage ranges using the ΔU potentiometer located on the front side. 1. Measure the output voltage on each power supply unit's R+. 2. Turn the ΔU potentiometer to the desired output voltage (approx. 21.6...26.4 VDC) 3. Repeat step 2 with all power supply units connected in parallel. 4. Use a clamp-on ammeter to verify that the current of all power supply units connected in parallel is distributed uniformly. 5. If the current is not distributed uniformly, use the ΔU potentiometer to adjust the output voltage. 10 of 12
