SAFETY REGULATIONS FOR ELECTRICAL EQUIPMENTS IN
LOW-VOLTAGE POWER INSTALLATIONS
5. Electric connection
The connection is to be realized only by
qualified skilled persons and in released
state being protected against re-starting. All
the data being necessary for that are to be
taken from the operating and maintenance instructions
delivered with the equipment. Before re-starting the
installation for the first time, there is to be checked
if the electrical equipment is running in the required
direction of the rotation. When exceeding the tolerances
according to DIN VDE 0530 part 1 / DIN EN 60034-1 (for
voltage ± 5%, for frequency ± 2%) and when deviating
from the waveform and the symmetry, the temperature can
possibly rise and the electromagnetic compatibility can be
impaired.
6. Operation
The maintenance measures specified in the operating
and maintenance instructions are to be carried out by a
qualified personnel in regular periods. The reasons for every
variation in view of the normal operation, in particular the
reasons for modified noise, for modified temperatures and
for the reaction of protective devices are to be determined
and eliminated by qualified personnel. If there’s any doubt,
the equipment is to be switched-off immediately.
7. Important information
Because of the great variety of the operating conditions
and for the clear understanding of the operating and
maintenance instructions, it is only the general case of
application which can be considered in this operating and
maintenance manual. For special cases (such as exceptional
environmental conditions or special safety instructions) it is
necessary to come to an agreement with the manufacturer
or with the selling company.
8. Warranty
The warranty requires the observance of the safety
regulations and of the operating and maintenance
instructions as well as the intended use.
1. General endangerings
These safety regulations are valid in connection with the
operating and maintenance instructions of the product
and they are to be observed strictly. Electrical machines
are equipped with hazardous live parts and rotating parts.
Therefore, severest personal and physical damages can
be caused through non-intended use, because of faulty
operation, through imperfect maintenance and because
of non-permissible disassembly of protective devices. It is
to be quaranteed that only qualified persons (definition
for skilled persons see DIN VDE 0105 or IEC 364) will be
engaged to realize any work at the equipments (such as
design, transport, assembly, installation, commissioning,
maintenance, repair, disassembly), though it should
be noted that the documents for the mounting, the
commissioning, the operation, the maintenance and the
repair of the equipment are available and that they are to
be observed.
2. Intended use
The machines are intended for industrial power
installations. The conditions on the site have to coincide
with all data given on the rating plate. In particular the
indicated degree of protection is to be realized by the
driven machine. Corresponding details are part of the DIN
VDE 0530 T. 1.
3. Transport, Storage
The ring bolts or shackles of the equipments are exclusively
intended for transporting the equipments. Additional parts
or loads must never be attached. Before the commissioning,
existing transport lockings are to be removed. Electrical
equipments with recognizable damages must never be put
into operation.
4. Mounting of the equipment
When mounting the electrical equipment there is to be
observed that the informations about the technical data
and operating conditions (such as determined in the
documents being part of the equipment), the general safety
and mounting regulations and the specific regulations
of the installation and of the operation are followed. In
case of types of construction with the shaft end upwards,
there must be taken measures preventing that foreign
matters can fall into the ventilation system. For ensuring
the unhindered ventilation of the machine, there are
to be followed the informations given by part of the
manufacturer.
