5.10.1 Electric motor
WARNING
Risk of explosion due to electric ignition sparks or electrostatic charging.
If inadmissible components are used for the ATEX marking and ATEX zone, the unit may carry
an electrostatic charge. Electrical ignition sparks can lead to an explosion.
„
The motor used must be suitable for the required ATEX marking.
„
Integrate the motor into the unit potential.
ATTENTION
Electric motors with a nominal output of 3 kW or more must be operated with star-delta start -
ing. Increased switching frequencies ("cycling") of the motors lead to premature malfunctions.
„
Wire the motor according to the supplied circuit diagrams.
„
Measure the power consumption on all three phases and compare the measured values with the values on the mo-
tor type plate.
ATTENTION
„
Wiring must be carried out according to DIN VDE 0100-100, DIN EN 60204-1
(DIN VDE 0113) and DIN EN 50156-1 (DIN VDE 0116).
„
Motor wiring must be designed so that the motor can be moved to the V-belt tension.
„
The power consumption may only be measured with the maintenance doors and main-
tenance panels closed due to the risk of overloading the motor. The power consumption
must not exceed the specified nominal current.
„
With multistep motors, operation via a frequency converter is not permitted.
„
Depending on the motor, frequency converter or fan manufacturer, a sine filter must be
taken into account.
„
If the motor is speed-controlled, the frequency converter - in combination with the addi-
tional MCB112 plug-in board - can also be used to evaluate the PTC thermistor.
„
Alternative evaluation via a separate PTC thermistor evaluation unit with corresponding
ATEX approval.
„
All other motors must be protected with an overload circuit breaker.
„
For adjustable motors, the maximum power consumption of the transformer and the mo-
tor must not be exceeded. For adjustable motors, the motor protection must be dimen-
sioned accordingly.
„
All electrical clamping points must be retightened.
„
If the motor is operated via a FC or EC technology, the combination can be secured using
a residual current circuit breaker. For this purpose, an all-current sensitive residual cur-
rent circuit must be selected.
NOTE
The operating and assembly instructions of the motor manufacturer must be observed.
