You must check whether the following data on the gear model plate agrees with the permis-
sible explosive area on site:
- Equipment group
- Ex category
- Ex zone
- Temperature class
- Maximum surface temperature
Make sure that when fitting the gearbox there is no explosive atmosphere, oils, acids, gases, vapours or radiation.
Check whether the ambient temperature is within the range of application in accordance with section Installation
Notes.
Ensure that there is enough ventilation to the gear and there is no external heat source (e. g. from couplings).
The cooling air must not exceed a temperature of 40°C.
Check that the conguration matches the conguration specied on the gear's model plate.
Please note: The design may only be changed after prior consultation with Sumitomo, otherwise the ATEX ap-
proval will lapse.
Please check that all drive parts to be installed are ATEX approved.
With gears with adapters, make sure that the data given on the gear's model plate is not exceeded
With mains operated motors:
Check that the data given on the gear and motor model plates matches the environmental conditions of the instal-
lation location.

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 Sumitomo, 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 permissible dierence from ambient tempera-
ture: 55 K. At a value of >55 K stop the drive immediately and contact Sumitomo.
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).
