The motor should be installed according to the following guidelines:
- Follow the installation instructions provided in the complete manual.
- Ensure that the motor is installed by qualified personnel who are familiar with safety requirements.
- Comply with the relevant standards and regulations for electrical and mechanical installations, such as IEC/EN 60034-1, IEC/EN60034-2, IEC 60034-8, IEC 60034-12, IEC 60204-1, EN 60204-1:2018, IEC 60072, IEC/EN 60034-5, IEC/EN 60034-6, IEC/EN 60034-7, IEC/EN 60034-9, and IEC 60034-14.
Maintenance
Proper maintenance is essential for the safe and reliable operation of the motor. Follow these maintenance guidelines:
- Refer to the supplier and examine the complete manual for extra maintenance information.
- Disconnect the power before performing any maintenance work.
FAQ
Q: Can the motor be used in potentially explosive atmospheres?
A: No, the motor is prohibited for use in Atex classified areas.
Q: How should the temperature control probes be connected?
A: When temperature control probes are present, they must be connected to
a non-automatic reset release device.
Installation, operation and ma intenance manual
These instructions must be followed to ensure safe and proper installation, operation and maintenance of motors. They should be brought to the attention of anyone who install,operates or maintains this equipment. Ignoring these instructions may invalidate the warranty.
- Prohibition of use in Atex classified area.
- Confirm that the parameters on the nameplate meet your requirements.
- Confirm that the motor is not damaged. If found damaged not use the motor (and contact FELM®).
- Remove any shaft locking device fitted to provide safety during transportation. Re‐install it before transporting the motor again.
- Only lift the motor using the eyebolts or the lifting lugs integrated with the motor frame. Alternatively, follow any otherwise stated separate lifting instructions.
- Check that the eyebolts or the lifting lugs integrated with the motor frame are undamaged before lifting.
- Lifting eyebolts must be tightened before lifting. If necessary the position of the eyebolt must be adjusted with suitable washers. If there is more than one lifting lug, they must be used together to share the weight.
- The center of gravity of motors with the same frame may vary due to different outputs, mounting arrangements and auxiliary equipment. To move a motor with packing, a sling must be used to lift the motor under the base, or eyebolts or lifting lugs integrated with the motor frame should be used.
- After installation, confirm that the mounting (IM) is in line with the identification on the nameplate. Check that the drain holes are at the lowest position (where present).
- The temperature of the outer casing of the motor may be hot to the touch during normal operation.
- Do not open terminal box while energized.
- If there are any questions, please contact FELM®.
Observe the safety precautionary measures as follows:
the motor is intended for installation and use by qualified personnel,
familiar with relevant safety requirements.
If the motor is not installed, operated and maintained correctly, it could
become a danger to health and human life.
Before maintenance is carried out, all electrical supplies connected with the
motor and its auxiliary parts must be turned off. Ascertain that the motor is
already at a standstill.
Earth connections must be carried out according to the local regulations
before the motor is connected to the mains supply.
Any protection devices used, must also be earthed to prevent accidents in
service.
Any fitted thermal protection devices should not be left open circuit and
should always be used. The protection devices can ensure the life of motor.
Depending on the operating conditions and environment, the most suitable
degree of protection must be chosen to prevent any damage and accidental
contact with internal rotating parts or with live parts.
There should be no possibility of contact with live parts. In the case of
auto‐starting, auto‐shutting down and remote starting, there must be a warning
notice to state that the motor could start unexpectedly.
Before starting, confirm that all shaft keys are fitted firmly.
In order to prevent overload, it is advisable to install a device to monitor
the winding temperature.
Some Felm motors are provided with re‐greasing nipples for continuous
operation. These machines are intended for lubrication during operation by
qualified personnel who are familiar with relevant safety requirements. Any
rotating parts or live parts should be integrally protected.
Environmental requirements and operating conditions
Normal ambient temperatures limits are ‐20°C / + 40 °C if standard performance
is to be achieved.
Maximum altitude 1000 meters above sea level.
Relative humidity should be less than 90%.
Check that the motor has sufficient airflow. Ensure that no nearby equipment,
surfaces or direct sunshine, radiate additional heat to the motor. Check that
the fan cover is not obstructed to ensure proper airflow cooling.
Short period storage (not exceeding 3 months, for extra storage period examine
the complete manual ”Long period storage”).
The motors should always be stored in clean, dry, vibration free, dust free
and corrosive free conditions.
The motors should always be stored on a smooth foundation surface and entirely
free from vibration and easy for handling.
The storage place should not be located in uncertain environments, and not
located near to a boiler or a freezer.
The best temperature of the storage place is 5°C to 50°C. If the motor is
equipped with space heaters, they should be energized.
Every week, rotate the shaft by 90°.
Measure insulation resistance before starting and when winding dampness is
suspected. Resistance should exceed 1M ohm. If the 1M ohm resistance value is
not achieved, the winding is too damp and must be dried in an oven. If after
oven drying, the 1M ohm resistance value is still not achieved, the motor must
be rewound.
Lubrication
It is essential to use grease of good quality and with the correct soap base
and grade.
Re‐greasing method
- Before re‐greasing, the grease nipples should be thoroughly cleaned to prevent any accumulated dirt from being carried into the bearing with the new grease. The exit grease relief valve or plug should be opened to allow the proper venting of the old grease. Use a grease gun to pump grease through the grease nipple into the bearings.
- After re‐greasing, operate the motor for 10‐20 minutes to allow any excess grease to vent out. Close the grease inlet and outlet plug if fitted.
Types of grease
Grease with the correct properties is available from all major lubricant
manufacturers. If the brand of grease is changed and its compatibility is
uncertain, consult the FELM®.
The types of grease standard by FELM® are “Chevron SRI‐2” and “SKF LGHP2”.
Please use identical grease or its equivalents when maintaining and
re‐lubricating.
The conformity of the end product according to Directive 2006/42/EC
(Machinery) has to be established by the commissioning party when the motor is
fitted to the machinery.
