Liability disclaimer

We have checked that the contents of this document correspond to the hardware and software de­scribed. However, since deviations cannot be precluded entirely, we cannot guarantee full consisten­cy.

The information in this document is regularly checked, however, and the necessary corrections in­cluded in subsequent editions. Suggestions for improvement are welcome. Technical data are sub­ject to modifications.

Warning notices

These Operating Instructions contain information which you should observe in order to ensure your
own personal safety, as well to avoid material damage. The notices referring to your personal safety
are highlighted in the manual by a warning triangle. Notices referring only to equipment damage have
no safety alert symbol. Warnings are shown in descending order according to the degree of danger
as follows:

DANGER

indicates that death or serious injury will result if proper precautions are not
taken.

WARNING

indicates that death or serious injury may result if proper precautions are not
taken.

CAUTION

indicates that minor personal injury may result if proper precautions are not
taken.

NOTICE

means that material damage can occur if the appropriate precautions are not
taken.

Note

highlights important information about the product, handling the product, or part of the
documentation that is of particular importance.

In the event of a number of levels of danger prevailing simultaneously, the warning cor­responding to the highest level of danger is always used. A warning that uses a safety
alert symbol indicating possible personal injury may also include a warning relating to
material damage.

Qualified personnel

The device/system must only be set up and used in conjunction with this documentation. Transport,
commissioning and operation of the device/system may only be performed by qualified personnel.
For the purpose of the safety information in these Operating Instructions, a "Qualified Person" is
someone who is authorized to energize, ground, and tag equipment, systems, and circuits in accord­ance with established safety procedures.

Correct usage of Siemens products

Please observe the following:

WARNING

Danger in case of none designated use of the product!

Serious injury may result.

Siemens products may only be used for the applications indicated in the cata­log and in the relevant technical description. If third-party products and com­ponents are used, these must be recommended or approved by Siemens. To
ensure trouble-free and safe operation of the products, they must be appropri­ately transported, stored, assembled, installed, commissioned, operated and
maintained. The permitted environmental and ambient conditions must be ad­hered to. Notices in the relevant documentation must be observed.

CAUTION

Risk to be burnt!

Burns at the hands by hot surfaces of the equipment’s housing or the heat
sink!

Do not touch the surface of the housing and the heat sink and let it cool down
before an exchange.

Note

For ecologically compatible recycling and disposal of your old device, contact a certifi­cated waste disposal service for electronic scrap. Please dispose the old device ac­cording to the local regulations in your country.

Electrostatic Sensitive Devices ESD

Almost all electronic devices and modules are equipped with highly integrated components or ele­ments in MOS technology. For technological reasons, these electronic components are very sensitive
to overvoltage and, consequently, to electrostatic discharge.

The short designation for such electrostatic sensitive components/modules is: "ESD", which is the
commonly used international abbreviation ”ESD” (Electrostatic Sensitive Device).

NOTICE

Electrostatic Sensitive Devices ESD can be damaged!

The presence of this symbol on cabinet, rack or packaging labels indicates the
use of electrostatically sensitive devices and thus the touch sensitivity of the
respective modules. When touching the modules these can be damaged. This
can lead to an immediate failure or to a reduction of the life time of the mod­ules.

Open the packing only at an ESD workplace. Discharge the body of your own
by establishing of an electrical connection to the earth potential before touch­ing the module.

These modules can be destroyed by voltage and energy far below the limits of human perception.
Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not
electrostatically discharged.

Components which were subject to such overvoltage are usually not recognized immediately as being
defective, because the malfunction does not occur until after a longer period of operation.

When working on the system, the following points must be followed exactly to ensure the safe dis­charge of electrostatic charges:

∂ Before performing any work on the system, create a ground connection by wearing a

wrist band.

∂ Always place or work on components on a grounded, conductive surface.

∂ Only transport components in suitable protective bags.

Tolerances of the prescribed tightening torques

Note:

If not indicated differently, the tolerances of the prescribed tightening torques in these
operating instructions are ±10 %.

2 Application

2.1 Utilization

SIPLUS PSU is a power supply module in electronic cabinets for the feeding and sub-distribution of
the power supply DC 24 V. It was developed especially for use in instrumentation and control cabi­nets of the Siemens power station instrumentation and control systems SPPA-T2000 and SPPA­T3000 and the Siemens automation system PCS7. It serves for the protected power supply of cabinet
components like racks, fans, heat exchangers, thermostats, door contacts and cabinet lamps.

Figure 1: SIPLUS PSU

The SIPLUS PSU was designed for the installation into electronic cabinets with 19 inch modular de­sign. By turning the lateral mounting angles by 180° backwards it can also be screwed to rear as­sembly walls without problems (see Chapter 7 “Commissioning”).

2.2 Functions

The SIPLUS PSU integrates the following functions in a compact unit:

∂ Redundant cabinet feeding power supply DC 24V
∂ Separate branch terminals DC 24V for the power supply of an adjacent cabinet
∂ 20 supply outputs for sub-distribution of the DC 24 V supply within the instrumentation and

control cabinet

∂ Fuse Protection of the cabinet sub-distribution
∂ Manual switch-off of every single electrical circuit of the cabinet sub-distribution
∂ Monitoring and signaling of a blown fuse or detection of a failure
∂ Indication of the operating state of all power supply outputs (X1-20) via LED displays
∂ Electrical connection of the ground potential M of the cabinet feeding with cabinet ground
∂ Disconnection of the earth connection for plants with central earth connection point
∂ Flexible installation by lateral assembly brackets with several fixing options
∂ Test of the feeder diodes with power supply in operating state
