1.3 General
DANGER!
RISK OF ELECTRIC SHOCK.
When the STS operates, some of its parts are necessarily under a hazardous
voltage.
Do not remove the cover; there are no user serviceable parts inside.
There may be danger, loss of life or personal injury if warnings are not strictly
observed.
CAUTION
There may be damage to the equipment if procedures and practices are not
strictly observed and followed.
NOTE
Do not attempt to service the STS unless you have had proper training. Refer
all maintenance and servicing to properly qualified, skilled and competent
service personnel.
Properly qualified, skilled and competent service personnel are persons who:
•Are familiar with the erection, installation and operation of the equipment and the system that is
being installed.
•Are capable of performing switching operations according to safety technology standards and
entitled and authorized to switch the equipment on and off and to isolate from the voltage.
•Are instructed according to the standards of safety technology in the care and use of safety
equipment.
•Are trained to immediate rescue measures (first aid).
•Have completed instructions with appropriate confirmation of GE.
1.4 Intended use
•A Static Transfer Switch (STS) is designed to transfer power supply between independent AC power
sources, thus protecting the connected load from power supply interruptions. It protects automatic
systems for power industry, power supply systems for petrochemical industry, computer and
telecommunication centers, automatic and security systems of ‘intelligent’ buildings as well as other
equipment that is highly sensitive for power supply interruptions.
•The STS is intended to be operated by technically qualified personnel.
Technically qualified personnel are persons who (because of their training, experience, and position
as well as their knowledge of appropriate standards, regulations, health and safety requirements and
working conditions) are authorised to be responsible for the safety of the equipment, at all times whilst
carrying out their normal duties and are therefore aware of, and can report, possible hazards (observe
IEC 364, DIN VDE 0105 and national wiring regulations and accident prevention rules).
•The technical data as well as information concerning connecting requirements can be found on the
rating label and in this document and shall be strictly observed.

1.5 Transport, storage, unpacking
•The STS should be transported in a container truck with shock protection against moves during
transport. The STS should be belted to the wall of the container.
•Any special treatment during storage of the STS is not needed.
•Move the STS in its original package to the final destination room.
•Check for sufficient floor and elevator loading capacity.
•Immediately after unpacking carefully check the integrity of the equipment. In case you note
recognizable damage, do not connect any voltage to the STS, do not put the STS into operation, but
contact the nearest Service Centre.
1.6 Installation
The following instructions are provided for the personal safety of operators and also for the protection
of the described product and connected equipment.
•Observe the prescribed accident prevention and safety rules for the specific application.
•When installing the STS strictly observe all information on technical data and operating conditions.
Comply with all warnings, and strictly follow the procedures and practices as described in this manual.
•This STS is intended to be used in a controlled indoor environment and free of conductive
contaminants and protected against animal intrusion.
•Check for sufficient floor loading capacity.
•Avoid placing the unit in direct sunlight or near heat sources.
•It is important that the unit has adequate ventilation. Maintain air movement around and through the
unit. Do not block the air vents.
•The unit must be placed in a sufficiently ventilated area; the ambient temperature should not exceed
40°C (104°F).
•Do not install the STS in an excessively humid environment or near water.
•Avoid spilling liquids or dropping any foreign object into the STS.
•Emergency stop devices must be provided for all applications. An emergency stop must inhibit any
further uncontrolled operation.
•The electric connections must be covered.
•Earth connection must be checked for safe function after assembly.
•Countermeasures should be taken to avoid accidental turning on of previously switched off systems
through either a control vault or a third party (e.g. key switches).
•Do not touch electronic components. They may be electrostatic sensitive and are for that reason easily
damaged due to improper handling.
•To avoid potential health risks, electrical components should not be mechanically damaged or
destroyed.
•Isolate from mains and battery before installation or dismantling work, as well as for fuse changes or
post installation modifications.

1.7 Electrical connection
•All electrical connections are to be realized by properly qualified, skilled and competent service
personnel only.
•When working on live STS, be sure to comply with the applicable national accident prevention rules.
•Before putting into operation make sure that the rated voltage for the unit conforms with the local
supply voltage.
1.8 Operation
•These instructions cover normal operation in the automatic as well as in manual modes. Special
operating conditions, such as short circuit tests, input supplies, etc., are not covered in this document.
These operating modes require comprehensive knowledge of the overall system and should be carried
out by properly qualified, skilled and competent service personnel only.
•Operators shall make sure that the system is ready for operation and that all cabinet doors are properly
closed before switching it on.
•Warning signs are placed on all cabinet doors to warn of excessive voltage (over 50 V) in the control
cabinets, but also of voltages in the power section and enormous short circuit currents. These signs
supply a warning not to open the doors during operation.
DANGER ! High Voltage!
Only qualified personnel may carry out work or manipulation of the device.
•Operators are prohibited from performing any work inside the control cabinets.
•Service and maintenance will not be covered in this document.
1.9 Fire regulations
WARNING
Should a fire break out inside the system, a fire extinguisher with CO2 or
halogen must be used. Do not inhale vapors.

2.2 Description
Static Transfer Switches type STS-230-XX (STS-230-25, STS-230-40 and STS-230-63) are designed for
switching between two alternative electrical power sources without supply interruption for energy receivers. The
static transfer switch (STS) is connected to two sources of electrical power with terminals called X01 PRIMARY
SOURCE and X02 SECONDARY SOURCE. The rated voltage of both sources is 230V AC and the frequency
is 50Hz. Depending on the current settings and the state of the system, one of the two sources (PRIMARY
SOURCE or SECONDARY SOURCE) is “connected” to the output terminal called X03 STS OUTPUT. Possible
methods for transferring the load from one source to other one are explained in chapter 4.
Optionally the device is equipped with a Switch Board. The Switch Board consists of an Integrated Switch (K1,
K2, K3, K4 and K5) and it functions as manual bypass that allows uninterruptible exchange of the STS.
Mechanical arrangement of the Integrated Switch ensures “brake before make” type of switching and their
proper sequence.

Each single line on the diagram represents two wires inside the STS-230-XX.
PRIMARY SOURCE, SECONDARY SOURCE and STS OUTPUT connections consist of three wires each
including Protective Earth (PE).
