Avoid liquid at the drive shaft or the shaft sealing
ring in case of vertical installation according to IM
V3.
6.2.12 Coating
One-layer standard varnish (1K), waterbased, in
condutive form, RAL9005 jet black, nominal
thickness 40
µm
WARNING
Danger of explosion due to improper change of
the surface characteristics.
An additional varnish on motors for hazardous
areas is not allowed in order not to negatively
influence the surface characteristics (like e.g.
insulation resistance, electrostatic charging).
6.2.13 Noise emission
The typical sound pressure level Lp(A) is speci-
fied for the speed range 0 rpm up to the rated
speed in the chapter “Technical data”. The instal-
lation situation affects the noise emission.

Transport and storage
7.1
Storage
Store the motors in their original packaging in a
dry, dust-free, vibration-free and light-protected
place without direct solar radiation. Please
observe classes 1K21, 1B1, 1C1, 1S10, 1M11
specified for storage acc. to
DIN
EN
IEC
60721-3-1.
Please observe the following classification limita-
tions:

Shock load
Do not remove factory-fitted transport protection
devices such as
dust protection, shaft protec-
tion, blind screw fittings when storing the motors.
Keep the transport protection devices for later
use.
NOTICE
Damage due to moisture and humidity!
−
Protect the products from dampness and
corrosion.
−
Store them only in rainproof and dry rooms.
Additional measures have to taken upon commis-
sioning to ensure smooth functioning – irrespec-
tive of the storage time which may be longer than
the warranty period of our products. Warranty
extension is not a consequence.

●
●
●
Visual inspection of all parts to
be damage-free
●
●
●
Resurface the holding brake
●
●
Check the electric contacts to
verify that they are free from cor-
rosion
●
●
Let the motor run in without load
for one hour at 800 ...
1000
rpm.
●
●
Measure insulation resistance.
Dry the winding at a value of <
1kOhm per volt rated voltage.
