Info & Contact Addresses

ET System electronic GmbH 1

INFO & CONTACT ADDRESSES

ET System electronic GmbH was founded in 1986 in the heart of the Rhine-Neckar-Triangle. As a subsidiary of a leading

electricity utility group, the company quickly took on a leading role in the area of laboratory power electronics and

associated electrical measurement. The existing know-how in power technologies in the 90s gave rise to the “Power

Solutions” product division as a strong extension of the historical “Test & Measurement” range.

Since 1997, we have been working successfully as an independent, privately held company with customers in all lines

of business from industry, medical care, railway technology and automotive electronics.

By means of our high vertical range of manufacture and our ever expanding development division we can fast and

flexibly adjust to our customers’ requirements. Necessary approvals such as CSA, UL, VDE, TÜV etc. are flexibly carried

out by qualified personnel. The approval procedures are performed within the scope of development planning and thus

do not negatively impact the start of manufacturing. Permanent manufacturing control through accredited laboratories

and an ISO 9001 compliant quality management system guarantee a constant high-level series-production quality.

We offer repairs and adjustment for units outside of our warranty period. Please contact your local distributor for fur-

ther information:

Important Safety Instructions

4 ET System electronic GmbH

IMPORTANT SAFETY INSTRUCTIONS

Please read this manual thoroughly before putting the device

into operation. Pay regard to the following safety instructions

and keep this manual nearby for future purpose.

This operating manual is based on the state of technology at the time of printing. However, it is possible that despite

regular control and correction, the present document contains printing errors or deficiencies. ET System electronic

GmbH assumes no liability for any technical, printing or translational errors within this manual.

INITIAL OPERATION

UNPACKING

Please make sure that the shipping carton and the packaging is free of damage. If external damage is found, it is im-

portant to record the type of damage. Please keep the original packaging to ensure the device is adequately protected

in case it needs to be transported in the future or claims for compensation need to be asserted.

SETTING UP

To avoid electric shocks and product failure, the device should be installed in a temperature and humidity controlled

indoor environment. The ambient temperature must not exceed 50 °C. The device must never be exposed to liquids or

extreme humidity.

VISUAL INSPECTION

The unit must be examined immediately for defects or damages in transit. Damages caused during transport may be

loose or broken control knobs and bent or broken connectors. Do not use the device if any physical damage is apparent.

Please inform the carriers and a representative of ET System electronic immediately.

MAINS OPERATION

Make sure to verify the model number and voltage stated on the nameplate. Damages due to wrong power feed are

not covered by guarantee conditions.

The unit must only be operated when connected directly to the

mains. To avoid damage, do not connect the unit to

isolating transformers, auto -transformers, magnetic current

limiters or similar devices.

STRUCTURE OF THE MAIN CONTROL UNIT

The main control unit is divided into three modules: protection sampling, main control, display control.

DESCRIPTION OF CABLE CONNECTIONS

The following picture gives an overview about the cable connections of the main circuit:

Before installing the equipment, all switches need to be disconnected. The circuit cables must be connected according

to the diagram above.

CABLE WIRING

Use the voltmeter to confirm whether there is no voltage output in the distribution lines. Confirm whether all switches

of the variable frequency power supply are in the position “OFF”. The input and output cables can be selected according

to the cables recommended in the following tables.

Input distribution cables:

Input Current (A)

Input live wire (mm²)

Input zero line (mm²)

Input ground wire (mm²)

70.8 A

25 mm²

16 mm²

Output distribution cables:

Output Current (A)

Output live wire (mm²)

Output zero line (mm²)

Output ground wire (mm²)

LO: 83.3 A - HI: 41.7 A

25 mm²

16 mm²

The above recommended reference cables are multi-core flexible copper cables which can be selected by the user ac-

cording to the present input and output current situation. If the length of the input or output lines exceeds 20 meters,

it is recommended that the wire diameter of the cable should be doubled. Successively connect the input distribution

lines to the corresponding wiring terminals at the input and the output distribution lines to the corresponding wiring

terminals at the output.
