5.6 Tests before commissioning in Ex area
- Does the data on the gear box's rating plate correspond to the permissible explosive area on site?
- Is the drive undamaged? (Check for any transport or storage damage).
- Is there an explosive atomosphere (oils, acids, gases, vapours, radiation, etc.)?
- Does the design correspond to the information on the model plate? Attention: If the design has not
been changed by SCG, the ATEX approval will lapse.
- Is an unrestricted supply of cooling air guaranteed? Is any hot exhaust air being drawn in from other equiment?
The cooling air must not exceed a temperature of 40 °C.
- Are all drive parts ATEX-approved?
If possible, the gear box is to be started without load. If it runs quietly and without any odd noises, the gearbox is
attached to the driven machine.
Measure the surface temperature after about 3 hours. Maximum permitted absolute temperature 90 °C.
If the temperature exceeds 90 °C, shut down the drive immediately and contact Sumitomo (SHI) Cyclo Drive
Germany GmbH.

With frequency inverter operated gear motors:
Check that the gear motor can be operated by a frequency inverter. The frequency inverter's parameters must be
set to prevent overloading of the gear box (see gear box model plate).
5.7 Installation
The drive must be installed so that it is easily accessible for any top up lubrication.
The xing bolts must only be tightened rmly after a perfectly level, rigid, vibration-reducing base for the whole
installation area has been carefully made and after the drive has been aligned.
After approximately 4 weeks all xing screws must be checked again to ensure they are tightened to the correct
torque.
If the drive is loaded up to the maximum output drive torque or the max. shear force, not only must the feet be
xed with screws of strength category 8.8 but also additional positive locking connections (e.g. cylindrical pins
DIN 6325) must be provided.
Do not use bolts higher in strength than 10.9 for GG cast housings. In the event of vibrations, frequent changes of
direction and heavy impacts, the ring gear housing must be doweled.
Tightening torques of bolts
Drives that are installed in the open air or under very unfavourable environmental conditions, e.g. dirt, dust,
splash water or heat, must be protected by a cover. If this is done the open air feed on the housing surface must
not be adversely aected. Oil check and drain screws as well as breathing lters must be freely accessible.
If there is the risk of electrochemical corrosion between the gearbox and the driven machine (combination of
dierent metals, such as cast iron/ stainless steel) use plastic intermediate layers (2 - 3 mm thick). Also t screws
with plastic washers. Also earth the housing. Use earthing screws on the motor.
A corrosion-inhibiting version of the drive is available for use in moisture-prone areas or in the open air. Any paint
damage that occurs (e.g. on the bleed valve) must be touched up.
If the drive is painted or partially re-painted you must ensure that the bleed valve and the shaft seal rings are
masked carefully. After you have nished painting the adhesive strips must be removed.
