1. Safety and commissioning instructions
1.1 General
Attention: Read installation, operation and maintenance documents (BUW), terminal diagram,
additional terminal diagram and safety data sheet before transport, installation, commission-
ing, maintenance and repair, and observe the instructions!
These supplementary operating and maintenance instructions apply together with the operating and mainte-
nance instructions for standard motors, which contain the basic specifications for connection, assembly, op-
eration and maintenance, the spare parts lists and the documents previously specified.
This BUW is intended to help the operator to transport, install, commission and maintain the explo-
sion-proof electrical machine safely and properly.
Neither compliance with this manual nor the conditions and methods of installation, operation, use and
maintenance of the electric motor can be monitored by the manufacturer. Improper installation can cause
damage to property and consequently endanger personnel. We cannot therefore accept any responsibility or
liability for loss, damage or costs arising from or in any way connected with incorrect installation and im-
proper operation, use or maintenance.
Drawings and illustrations are simplified representations. Due to improvements and modifications, it is possi-
ble that they do not correspond in detail to the electrical machine supplied. We are constantly striving to im-
prove our products. We therefore reserve the right to make changes to the product, the technical data or the
assembly, operating and maintenance instructions without prior notice. Designs, technical data and illustra-
tions are only ever binding with written confirmation from the supplier.
1.2 Symbols
Three symbols are used in this operating manual to indicate particularly important passages:
Safety and warranty information,
including possible personal injury.
Warns of electrical voltage, danger to life.
Indicates that damage can be caused to the electrical machine and/or
the auxiliary equipment.
Ex additional information for electrical machines of equipment group II for
category 2 (zones 1 and 21) or equipment group II for category 3 (zones 2 and 22).
1.3 Safety regulations
The safety regulations, accident prevention rules, guidelines and recognized rules of technology
must be observed without fail!
Failure to observe the safety instructions can result in danger to persons and/or damage to the machine.
High-voltage machines > 1kV have dangerous, live and rotating parts, and possibly hot surfaces. All work
relating to transport, connection, commissioning and maintenance must be carried out exclusively by quali-
fied, responsible technical personnel (observe EN 50 110-1)
Improper conduct can cause serious personal injury and material damage.
Caution: Danger to life!
1.4 Intended use
These high voltage machines are intended for industrial plants. They comply with the harmonised standards
of the IEC/EN 60034 and IEC/EN 60079 series.
For use in ex areas, the additional instructions for the ignition protection type must be observed. The motors
are designed as standard for ambient temperatures from -
20°C to +40°C and installation altitudes of ≤ 1000
m above sea level.
The conditions at the place of installation must correspond to all the rating plate specifications
