4.4 Insufficient cooling water quality
NOTICE
Corrosion due to insufficient cooling water quality
The materials used in the cooler are selected to match the cooling water quality for which the
air-water cooler was ordered. The cooler cannot be simply used without taking any other
measures if other water conditions apply. If the cooling water quality is unsuitable, the air-towater heat exchanger may suffer corrosion and fail.
● The chemical composition of the cooling water must comply with the configuration
specifications.
● If the cooling water quality fails to satisfy the quality stated on the order, please contact
the Service Center.
● Please observe the recommended water quality in the operating instructions for the airwater cooler.
NOTICE
Overheating of the machine as a result of additives in the cooling water
Additives for antifreeze or corrosion protection can have a negative impact on the heat
transporting properties. The machine can overheat.
● Only operate the machine with the contractually agreed cooling water quality.

4.6 Interlock circuit for anti-condensation heating
4.6 Interlock circuit for anti-condensation heating
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine.
● Install an interlock circuit that switches off the anti-condensation heating once the main
machine is switched on.
● Only switch on the anti-condensation heating after the machine has been switched off.
See also
Switching on with the anti-condensation heating active (Page 78)
4.7 Space requirements
Ensure that there is sufficient space where the motor is to be installed so that when required,
the air-to-water exchanger can be removed and installed.
Preparations for use
4.8 Noise emission
Excessive sound pressure levels can lead to hearing impairment or hearing loss.
● When assessing the noise level of the system, make due allowance for the noise emissions
from the machine.
● If necessary, take suitable noise protection measures for personnel.
4.9 Voltage and frequency fluctuations during line operation
If nothing else is stamped on the rating plate, the permissible voltage fluctuation is ±5 % and
the permissible frequency fluctuation is ±2 %, corresponding to range A in IEC / EN 60034‑1.
Permissible fluctuations that go beyond this are stamped on the rating plate.
Under operating conditions a machine may sometimes have to be operated outside the limits
of range A.
● Exceeding the permissible tolerances for voltage and frequency can lead to an
impermissibly high temperature rise of the winding. This can result in long-term damage to
the machine.
● Limit exceptions of this sort with regard to the values that arise, how often, and for how long
they occur.
● Where possible and within a reasonable time take corrective actions such as reducing the
power. Such actions can avoid thermal ageing leading to a reduction in the service life of
the machine.

Preparations for use
4.10 Phase synchronization during supply system switching
4.10 Phase synchronization during supply system switching
Damage to the machine may be caused when switching to another supply system with different
phasing.
● The phasing must be synchronized during switching. Use appropriate means to
synchronize the phasing.
4.11 System-inherent frequencies
Excessively high vibration levels and system resonances can damage the machine set.
● Configure and match the system consisting of the foundation and machine set in such a
way that no system resonances can arise and result in the permissible vibration levels being
exceeded.
● The vibration limit values according to DIN ISO 10816-3 must not be exceeded.
4.12 Torsional loading of the shaft assembly
In the event of faults in the electrical connection, such as line switching operations with a
residual field or short circuit at the terminals, excessive air gap torques can occur. These
excessive air gap torques can lead to additional mechanical torsional loads on the shaft
assembly.
If the configuration does not correctly recognize the mechanical torsional loadings of the shaft
assembly, this can lead to serious damage to the machine. This can result in death, serious
injury or material damage.
● When planning the system, make due allowance for the maximum air gap torques that can
occur. This data can be found in the "Electrical data".
The system planner is responsible for the entire drive train.
4.13 Switching high-voltage motors
If vacuum circuit breakers and vacuum contactors are used, then what are known as multiple
restrikes can occur when the machine is switched off. This depends on various factors, such
as:
● Arc-extinguishing principle of the switch
● Machine size
● Length of the power supply cable
● System capacitance, etc.
A surge suppressor to ground is installed in the switchgear between the circuit breaker and
the cable termination for each of the three conductors. The level of protection for the machine
windings is sufficient when the limiter is correctly selected (machine rated voltage / response
voltage).
