Checklists
5.1.1
Before startup
This checklist includes all activities that will have to be executed
prior to startup
of a
gear unit according to Directive 2014/34/EU for operation in potentially explosive at-
mospheres.
Check prior to startup in potentially explosive atmospheres
Verified See
chapter
Inspect the shipment for damage as soon as you receive the delivery. Inform the ship-
ping company immediately about any damage. It may be necessary to suspend startup.
Remove any transport protection prior to startup.
2.6
Does the data on the nameplate of the drive match the situation on site for operation in
a potentially explosive area?
•
Equipment group
•
Explosion protection category
•
Temperature class
•
Maximum surface temperature
3.9
4.2
Have arrangements been made to prevent potentially explosive atmospheres (oils,
acids, gases, vapors or radiation) during installation of the gear unit?
Does the ambient temperature comply with the specifications (nameplate and order con-
firmation)?
3.9
Have measures been taken to ensure that the gear units are sufficiently ventilated and
that they are not heated by an external heat source (e.g. the coupling)?
The cooling air must not exceed the maximum ambient temperature designated on the
nameplate.
Does the mounting position correspond to the specifications on the gear unit name-
plate?
Do not change the mounting position without prior consultation with SEW‑EURODRIVE.
ATEX approval will become void without prior consultation.
7.0
Does the oil level for the mounting position on the gear unit nameplate correspond to the
indicated oil fill quantity?
3.9
Are all oil level plugs, oil drain plugs as well as breather plugs and breather valves freely
accessible?
7.6
Do all input and output elements to be installed have ATEX certification?
Ensure that the data specified on the nameplate are not exceeded for stand-alone gear
units with adapters or input shaft assembly.
3.9
Is the cover mounted properly for gear units with hollow shaft and shrink disk?
4.11
Ensure that no spacer bushing is used as assembly aid during the installation of the AM,
AQA adapter.
4.14
4.15
When mounting a motor on the AD input shaft assembly:
•
Does the belt have sufficient electrical leakage resistance < 10
9
Ω between input
shaft end and motor shaft?
•
Before mounting a protection cover: Does a risk analysis performed by the manufac-
turer of the protection cover demonstrate that no sources of ignition can occur (such
as impact sparks from grinding)?
