Excessive pollution, dust, chips, oil, water and similar liquids can cause negative effects
on the motor and the brake assembly. Therefore, the motors must be cleaned regularly,
and the surface of the motor must be protected against such effects.
The motor must not be connected directly to the main power grid without a driver! The
motor must be connected to a suitable driver, and it shall never be operated without
taking all safety precautions and making the necessary driver adjustments. All the metal
parts of lift installations must be grounded. The grounding connection must be connected
to the motor driver. The grounding line must absolutely be separate from the neutral line.
The length of the motor cable shall not exceed 25 m.
Driver (inverter) settings and identification of encoder angle must be
carried out separately for each motor. Otherwise, dangerous and
uncontrolled accelerations may occur.
According to the national and international color code directives, the NEUTRAL line
must be blue and the GROUND line must be green-yellow.
There is a risk of electric shock in cases of short circuits in the stator. The electrical
system connected to the motor must be de-energized carrying out any work on the motor.
If there is a damage to the motor cables, the cables must not be touched until the power
is cut off. The cables can only be changed after power is cut off.
Touching the body of the motor before it cools can cause burns. In case of extreme
heating (100 °C) or abnormal noise during motor operation, deactivate the motor
immediately. Check the possible motor failures section and contact with the
manufacturer if necessary.
The surfaces of the motor must be kept clean. Insufficient heat transmission on motor
surfaces may reduce the life of the motor. The motors can be damaged if necessary
precautions are not taken. The motor heat sensor must absolutely be connected to the
necessary protective circuit.
The distance between the motor and persons who have cardiac
pacemakers must be at least 0,5 m.
