Only qualified personnel are allowed to perform any planning, installation or maintenance work.
The personnel must be trained for the job and must be familiar with the installation, assembly, commissioning and operation of the
product.
The instructions given in this manual or any other instructions supplied must always be observed.
Safety instructions
The motors of the series DUM/F 6 are designed for use in commercial plants. They comply with the harmonised standards of the
series VDE0530/EN60034. They are not to be operated in hazardous areas unless expressly permitted (note additional refer-
ence).
The local conditions on site shall comply with the nameplate data. During operation (even at zero speed), the motors possess dan-
gerous live and moving parts and may have hot surfaces. Only qualified and competent specialist personnel are allowed to han-
dle, connect, commission and maintain the motors. (Observe VDE0105; IEC364). Improper conduct may result in serious injury to
persons and property.
In this manual, the following pictograms are used to mark warnings and important notes.
means that death or serious injury to persons or property will occur unless the appropriate precautions are
taken.
means that death or serious injury to persons or property may occur unless the appropriate precautions are
taken.
means that slight injury or damage to persons or property may occur unless the appropriate precautions are
taken.
·
Remove power to the machine before starting any work on the motors.
·
Check the proper functioning of the brake (if provided) after installing the motor.
·
Repairs may only be carried out by the manufacturer or an authorised repair agency. Unauthorised opening
and tampering may lead to bodily injury and property damage and may entail the loss of warranty rights.
·
Before commissioning motors with a shaft key, secure the key to ensure that it cannot be thrown out if this is
not already prevented by driving elements such as a belt pulley, coupling, etc.
·
The motors are not designed for direct connection to the three-phase system but are to be operated via an
electronic power converter. Direct connection to the system may destroy the motor.
·
Surface temperatures of more than 100°C may occur on the motors. Therefore, no temperature-sensitive
parts must be allowed to come into contact or be attached to them. Protection against accidental contact
should be provided, if required.
·
The optional holding brake is only designed for a limited number of emergency brakings. Never use it as a
working brake.
·
On motors with plug connector and built-in brake, it is the user's responsibility to install the varistor provided
to control the brake.
·
Connect the winding temperature sensor and evaluate its signal by means of a suitable circuitry. The temper-
ature sensor protects the motor from thermal overload if the temperature change is slow. It does not, howev-
er, provide an allround protection. Therefore, additional measures such as monitoring I
2
t by the converter
electronic system are required to protect the motor from fastarising thermal overload.
·
Dangerous voltages are applied at the terminals of synchronous motors when the rotor is turning.
