3.2 Special versions
The following special versions (amongst others) can be supplied in consultation with the manufacturer (not for
every type):
• 24 VDC;
• Version for non-standard mains voltage and/or frequency;
• Versions for use with high relative air humidity (RH > 60%);
• Non-standard approvals.
3.2 Conditions of use
The following conditions of use are applicable when using the motor gearbox:
• Operating ambient temperature range:
• Above 0.6 kW: -15°C to 60°C [5°F to 140°F];
• Below 0.6 kW: +5°C to 60°C [32°F to 140°F];
• Max. force on output shaft:
• GW10: radial 1,000 N, axial 400 N
• All other types with the exception of GW10: radial 4,000 N, axial 400 N;
• Hoisting of freely suspended loads (not persons), such as a growth tube or chrysanthemum (hoistable) heating
frame or assimilation lighting, is only permitted with a fall-arrest brake protection system;
• The motor gearboxes are suitable for S3-30% operation;
• The maximum continuous on time is 25 minutes;
• The motor gearbox may be cycled a maximum of 3 times per minute;
• The service life of the motor gearbox increases significantly with low loads and switching cycles which allow
intermediate cooling of the motor gearbox.
3.3 Restrictions on use
Structural modifications to the motor gearbox are not permitted. Any such modifications render the manufacturer's
warranty null and void and relieve the manufacturer of liability for any consequences. In addition, the following
restrictions are applicable with regard to the use of the motor gearbox:
• Do not load the motor gearbox or drive train with a torque greater than the maximum specified torque;
• Do not use the motor gearbox to operate parts located in the immediate vicinity (within easy reach) of people.
Maintain safe distances in accordance with EN ISO 13857;
• Do not expose the motor gearbox to direct water spray, rain or snow;
• Do not use the motor gearbox to operate smoke and heat exhaust ventilation systems compliant with NEN
6093 or DIN 18232;
• Do not use the motor gearbox to operate automatic doors or gates used by people;
• Do not use the motor gearbox in explosion hazard areas if express permission has not been granted to do so.
3.4 Unintended use (misuse)
We expressly warn against the following types of unintended use:
• Do not use the motor gearbox for lifting suspended loads in areas in which people are present;
• Do not use the motor gearbox for transporting people (for example, for passenger lifts, etc.).
3.5 Storage
To safeguard the service life and correct functioning of the motor gearboxes, the following rules must be followed:
• Ensure that the motor gearboxes are stored in a dust-free and moisture-free environment;
• The relative air humidity of the storage location must be less than 50%;
• Store the motor gearboxes at temperatures between -15 and +60°C [5°F to 140°F];
• Avoid sudden changes in temperature to prevent the formation of condensation.
If you wish to store the motor gearboxes for a lengthy period of time, you can use preservatives to protect the
unpainted surfaces, such as threaded holes and mounting surfaces for chain couplings, against corrosion.
