General Safety Information Ordinances and Regulations
REGATRON Performance. Precision. Quality. TC.ACS - Device Manual (V04.60) - 26.4.2022 9 / 66
1.2 Ordinances and Regulations
Follow the mounting and installation instructions during electrical installation!
In particular, in the countries of the European Union the following standard applies:
EN 62477-1 Safety requirements for power electronic converter systems and equipment
If you want to use the electrical power supply in special applications, you must comply with the related standards
and health and safety regulations.
Due to the high operating voltage and the high output voltages, an industrial electrical power supply represents a
mortal hazard.
To avoid serious injuries or significant damage, only appropriately qualified personnel who are familiar with
industrial electrical power supplies are allowed to work on the devices. These individuals must carefully read
these operating instructions prior to installation and commissioning and follow the safety instructions.
Electronic devices are in principle not fail-safe. The user is responsible for ensuring that the electrical power
supply, mains supplies and loads connected to it are placed in a safe state in the event of a failure of the device.
1.3 Categorization of the hazard Areas
The assessment of the effects of hazards from low-voltage systems with a flow of energy for supply and possibly
regeneration is divided into the following areas:
• Personnel Area (1.3.1)
• Systems and Material Area (1.3.2)
• Mains Connection Area (1.3.3)
• Surrounding Area (1.3.4)
• Area related to Interaction with the Device (1.3.5)

General Safety Information Categorization of the hazard Areas

1.3.1 Personnel Area
The utmost attention is to be paid to the hazards for individuals. There are various risks and hazards, the most
important of which are mentioned here.
1.3.1.1 Electric shock
The system can produce electrical potentials that can be dangerous or even fatal for individuals. During work on
the system the following guidelines are to be observed:
• Work in electrically isolated state
This is the recommended way of working, it should be rigorously applied during all connection and wiring
work. Follow the rules:
Electrically isolate.
Secure against switching back on.
Discharge and short-circuit capacitors, disconnect and isolate batteries.
Verify the voltage free status by measurement.
Connect to earth.
Report and instruct.
• Work in the vicinity of live parts
In these circumstances an increased hazard potential is to be expected. Minimize the risks by means of:
Guards
Covers
Insulating encapsulation, cladding
Imposed separation by means of mechanical features, protective grilles
Supervision, reporting
• Work on live equipment
It is imperative that this form of working is avoided. If it cannot be avoided, careful work preparation is essen-
tial. Pay attention to the following:
The personnel must be specially trained.
Work in accordance with recognized specialist methods.
Controlled personal protective equipment must be available (passive protection).
Organization of the working areas.
Supervision and preparatory measures (active protection).
Use appropriate protection against physical contact throughout.
Set up a suitable emergency stop chain and test it at regular intervals.
Mark all wires and cables to prevent mistakes.

1.3.1.2 Electrical Heating
TC.ACS power supply systems operate with significant amounts of energy. High currents can cause heating of
cables and wires. In particular, during unmonitored endurance tests insulation fires and short-circuits may be
caused.
• At particular risk are connectors, switchgear and cable terminals. Check these parts particularly carefully and
at regular intervals.
• Use wiring material suitable and stipulated for your application with the related insulation class.
• Monitor your system actively or passively using appropriate sensors or by monitoring parameters.
1.3.1.3 Arcing and sparking on opening Contacts
Note that on opening a circuit through which a current is flowing, arcing with very high energies can be produced
depending on the inductance!
In some circumstances this arcing can result in burns, damage to the eyes as well as damage, destruction or fire
on parts of the system. The usage of appropriate DC contactors as isolating devices in DC circuits is
recommended! In case of doubt contact the related manufacturer. Take into consideration that the protective
devices on the TC.ACS system cannot detect an arc as a fault condition, as this situation may be a required
function.
1.3.1.4 Mechanical Injury
As on all electrical installations, mechanical injuries to the head and hands may be caused on removing and fitting
covers, wire and cable connections. Always use the correct tool. If necessary protect the head and hands against
injuries due to cuts and impacts.
1.3.1.5 Chemical Injury
While handling with cooling liquid, open doors and windows and ensure the room is well ventilated also on the
ground level. Avoid work which leads to the formation of aerosols. Use, if necessary the personal safety
equipment:
• Use the respiratory protection at short time and existing low concentrations of vapor and aerosols. Use
breathing apparatus with independent air supply at long time and high concentrations of vapor and aerosols.
• Use protective gloves which are resistant against acids and solvents and safety gloves to avoid direct skin con-
tact.

1.3.2 Systems and Material Area
1.3.2.1 Fire
TC.ACS power supply systems are manufactured from nonflammable materials exclusively.
In case of fire, electrically isolate the system immediately, on the one hand to interrupt the supply of energy and
on the other hand to shut down the fans.
Fight the fire from bottom to top in accordance with the rules in your organization using suitable firefighting
equipment (CO2 fire extinguisher). If possible use fire extinguishers with asphyxiation action to keep the
secondary damage low.
1.3.2.2 Electromagnetic Fields
Like any electrical system, TC.ACS systems produce electrical and magnetic fields. However, these fields comply
fully with the usual standards.
Note that particularly the EM fields from your wires and equipment connected could nevertheless produce
interference on objects in the immediate area.
• Keep data carriers and PC-based measuring environments at an adequate distance from live wires to prevent
interference and data loss.
• Protect highly-sensitive sensors and instruments.
• Test effects on communication networks, in particular radio networks.
• Make individuals with electronic implants aware that implants may be affected.
1.3.2.3 Noise and Noise Level
The inductive elements as well as the fans on the TC.ACS low voltage system produce a lower or higher noise level
dependent on the operating mode. However, in the immediate vicinity of the cabinet this noise is under the
tolerance limit that would make acoustic protection equipment necessary.
The usage of acoustic protection equipment or acoustic insulation measures can be necessary in specific
circumstances.
1.3.2.4 Mechanical Damage
Incorrect operation of the systems can result in mechanical damage to the downstream equipment and systems.
In particular, on the supply of power to drives it is to be ensured, that excessively high speeds cannot result in
load shedding. The monitoring of the maximum speed with intervention in the safety chain is recommended
above all.

1.3.2.5 Handling Storage Systems containing large Amounts of Energy
Modern energy storage systems are able to absorb very large amounts of energy. This situation has the following
consequences:
• The cabling should not just comply with the maximum charging and discharging currents to be expected, to
some extent significantly higher peak currents are to be expected during switching processes.
• A short circuit or failure can be very serious in the case of storage elements containing large amounts of
energy. Due to the high currents serious injuries and serious damage can be caused. The following, incomplete
list indicates some of this damage:
Burning of wires and connectors
Sparking
Fires, insulation fires
Arcing, welding
Electric shocks
• Never short-circuit energy storage systems to discharge them! Always use a suitable discharge resistor of
appropriate power rating!
• Visibly secure a discharged energy storage element using a short-circuit bridge.
• Always monitor the maximum storage element voltage, also during practical test operation.
• Use a device that clearly indicates the charge state of the energy storage element, e.g. by monitoring the
voltage.
1.3.3 Mains Connection Area
When a TC.ACS power supply device is switched on, there may be an uneven load on the three phases; this
uneven load may cause older residual current circuit breakers to trip. Here a modern make of residual current
circuit breaker is to be used that will tolerate such asymmetries during the switch-on process.
1.3.4 Surrounding Area
TC.ACS power supply devices are generally forced-air cooled (some are water-cooled in addition). Despite the
very high efficiency, a power loss occurs in the components that must be dissipated in the form of heat to the
surroundings. The energy is dissipated with the aid of forced ventilation to the rear of the TC.ACS device. It is to
be ensured that the rooms in which TC.ACS power supply devices operate are cool so that the heat produced can
be removed. It is to be ensured that there are no undesirable effects (e.g. stirring up of dust or sand, deformation
due to the action of heat etc.) due to the flow of air and the heat, which at high load may be powerful.
1.3.5 Area related to Interaction with the Device
Compliance with the design data for the specific device is a prerequisite for malfunction-free operation. Load
systems can have significant effects on the power source. The following points are to be noted:
• The maximum voltage specified must not be exceeded.
• Protective measures must be provided against voltage spikes on the load side and their function must be
monitored (voltage spikes could damage the filter capacitors and semiconductors in the device).
• Periodic over currents are to be avoided.
• The ripple currents produced on the load side are to be monitored to avoid overloading filter capacitors; in
case of doubt ask the manufacturer.
• The device is always to be operated within the permissible temperature range. High temperatures will
significantly reduce the service life of various components.

2 Introduction
This section includes the following subsections:
• Range of Application (2.1)
• Control Interface (2.2)
• Model Identifier (2.3)
2.1 Range of Application
The full 4-quadrant grid simulator TC.ACS allows for all relevant testing according to the grid-feed-in regulations
(CENELEC, DIN, IEC). It can be operated in the following modes:
• Waveform Generator Mode (2.1.1)
• Amplifier Mode (2.1.2)
• Load Simulation Mode (Option) (2.1.3)
Generally, the device is capable of 4-Quadrant Operation.
2.1.1 Waveform Generator Mode
There are the following kinds of the waveform generator mode:
• Basic Waveform Generator Mode (2.1.1.1)
• Full Waveform Generator Mode (Option) (2.1.1.2)
2.1.1.1 Basic Waveform Generator Mode
In the basic waveform generator mode the TC.ACS device simulates a grid. I.e. it generates a signal waveform that
resembles the signal given by a grid, i.e. a sine wave. This signal can be configured and controlled via ACSControl.
2.1.1.2 Full Waveform Generator Mode (Option)
In the full waveform generator mode the TC.ACS device simulates a grid or any other kind of electrical source. I.e.
it generates signal functions that resemble those being generated by the respective source. Here ACSControl
allows to generate all kinds of signal waveforms and sequences of these in order to represent the influences of
various factors (e.g. failures or interferences in the power system).
2.1.2 Amplifier Mode
In the amplifier mode the TC.ACS device works as a triphase voltage or current (option) amplifier. I.e. it receives
external signals via its analogue interfaces for each phase. These signals are amplified and then transferred to the
output. Here any device, which creates electrical signals, can be used as an external signal generator.

2.1.3 Load Simulation Mode (Option)
In the load simulation mode the TC.ACS device simulates loads and their properties within specified RLC-circuit
topologies.
2.1.4 4-Quadrant Operation
The TC.ACS supports the feeding mode and the regenerative mode as a part of 4-Quadrant operation modes.
Here the sign of the power determines the direction of the energy flow, and hence whether Feeding Mode
(positive Power) or Regenerative Mode (negative Power) is active.
Alternating grids change between feeding mode and regenerative mode according to their reactive power by
phase shifting between voltage and current.
2.1.4.1 Feeding Mode (positive Power)
In the feeding mode energy flows from the line to the device under test (DUT):
2.1.4.2 Regenerative Mode (negative Power)
In the regenerative mode energy flows from the device under test (DUT) to the line:
2.2 Control Interface
The TC.ACS device can be operated via a PC with the software ACSControl, exclusively.
The load simulation mode is an optional feature. It needs to be enabled via key code and an
external hardware filter may be needed in some applications (see Application Notes). Contact
Regatron Customer Support, if necessary.
The software ACSControl is included in the scope of delivery.
