Page 14: Disposal
Assembly instructions Centrifugal-motorized impellers Mounting • Secure pallets during transport. • Do not stack pallets. • Only handle with suitable hoisting gear. • Never stand underneath the suspended fan because defective transport equipment could cause death. • Store the fan / motor in the original packaging in a dry area protected from the weather and protect it from dirt and weather until final installation. -
Page 15: Special Installation Features For Explosion-Protected Motor Impel- Lers
In terms of material selection, due to special protective measures relating to possible contact surfaces between rotating and stationary components (impeller end plate, cover disk / inlet nozzle), ZIEHL-ABEGG centrifugal motor impellers satisfy the requirements of the EN 14986. standard. -
Page 16: Protect From The Penetration Of Foreign Bodies
• Comply with the permissible material combinations of rotating and stationary housing) parts according to DIN EN 14986. A copper inlet nozzle can be ordered from ZIEHL-ABEGG SE as an accessory. This complies with the specified material pair. Danger! The following principle applies in general:Fans that do not comply with the required minimum gap dimensions must not be put into operation under any circumstances! RE..P... -
Page 17: Sealing
RH56M RH63M The possible contact diameter corresponds to the internal diameter at the aspirating hole in the impeller, which is specified on ZIEHL-ABEGG SE dimension sheets as “DSI” (RE..P) or “DE” (RH..M). Danger! Always check the gap dimension with a feeler gauge before start-up. Safe operation is only guaranteed if it is compliant. -
Page 18: Connection Cable & Junction Box
If the line ends are connected to the external circuits in the potentially explosive area, a junction box suitable for this area must be used. Appropriate explosion-proof junction boxes with tested cable and line inlets are available in our ZIEHL-ABEGG parts lists. Allowed medium temperature see intended use. -

Page 20: Motor Protection
The motors contain triple thermistors. No more than two PTC thermistor chains may be connected in series, as this can lead to undefined shutdown. • Tripping device for motors with thermistors “TP” (PTC thermistor) e.g. ZIEHL-ABEGG type U-EK230E with switch-off via a contactor. •... -
Page 21: Start-Up
Assembly instructions Centrifugal-motorized impellers Start-up For operation with electronic voltage controllers using phase cutting, observe the following: • As well as the rise in current due to voltage reduction, an additional rise in current occurs due to harmonics. The value of this additional rise in current depends on the control methods of the electronic voltage controller and cannot therefore be specified on a general basis. -

Assembly instructions Centrifugal-motorized impellers Start-up 11. Connection data complies with the specifications on the rating plate? 12. Thermistors “TP” (PTC) and triggering device have been properly installed and are operational? Information If motor impeller units are stored or operated after long periods without use, or if they have been exposed to condensation over a longer period, the insulation resistance of the motor winding must be measured before start-up(or restarting). - Page 23 (contact ZIEHL-ABEGG SE service if necessary). 3. ZIEHL-ABEGG SE fans are delivered balanced in compliance with DIN ISO 21940-11 for the corresponding fan category as set out in ISO 14694.

Please observe the safety regulations and the worker´s protection rules by all maintenance and service work (EN 50 110, IEC 60364-1). • Replacement of the ball bearings is only allowed by the manufacturer ZIEHL-ABEGG. • As the opening on the motor is partially covered by the rating plate, and as custom bearings with special ZIEHL-ABEGG lubrication are employed, only ZIEHL-ABEGG SE is allowed to carry out the bearing exchange. -
Page 28: Particularities When Using In Explosive Atmospheres
Be aware of the following Points: • ZIEHL-ABEGG recommends that during the phase of commissioning of a new fan, a visual inspection during which the fan is especially checked for the tight seating of all bolted connections, dirt, vibrations and unusual noises is undertaken at least weekly. -
Page 29: Cleaning
Assembly instructions Centrifugal-motorized impellers Maintenance 8.3 Cleaning To avoid risks of imbalance, the impeller must be checked and cleaned regularly. The impeller must be cleaned and dusted at least once a year. Depending on the place of use, this interval can also be shorter to exclude all risks of imbalance. Danger due to electric current •... -
