Use of this equipment in
hazardous locations is prohibited
unless expressly provided for (refer to addi-
tional information).
Never
use equipment with system of protection IP 23 or below out of doors. If special cir-
cumstances apply, e.g. the equipment is used in a
non-commercial
situation where stricter requirements
must be met (such as special guards to protect children from moving parts, for example), these require-
ments must be met by the customer at setup. Motors
are rated for ambient temperatures of b
5° C and + 40° C
and site altitudes of
1,000 metres above sea level or less.
The permissible reference relative humidity levels in these cases are as follows: in the case of
indoor
setup,
between
20% and 75%
in the temperature range
+5° C to +40° C;
with
outdoor setup,
between
36% and 98%
in the temperature range
+5° C to +40° C.
In this connection, with outdoor setup, the
ab-
solute humidity
at more than
25° C must not rise above 23g/m
3
(this corresponds to a relativen humid-
ity of 95% at 27° C).
Observe any information that differs from the data on the rating plate. On-site conditions at the place of
use must correspond exactly with
all
the information on the rating plate.
Low-voltage machines are
components
for installation in machines in the sense of machine guideline
89/392/EWG.
Commissioning
may not be carried out until it has been determined that the end product
conforms to this guideline
(observe EN 60204-I
).
1.3 Transportation, Storage
Immediately
report any
damage
that you may have found after delivery to the carrier. If necessary,
commissioning should be postponed.
Tighten screwed-in transportation rings. These are designed to
bear the weight of the low-voltage machine and you should not subject them to any
additional loading.
If
appropriate, use suitable, adequately rated means of transportation, e.g. rope guides.
Before carrying out commissioning, remove the
transportation safety devices.
Use them again if the
equipment is to be removed, or, if you do not need them any longer, return them to Baumüller GmbH in
Nuremberg.
If the motors are to be kept in storage, ensure that the local conditions are
dry, dust-free and low-
vibration
(v
eff
≤
0.2 mm/s) to avoid damage due to bearings being idle. Before commissioning, measure
the insulation resistance. With values of
1 M
Ω
or less, dry the coil.
1.4 Long-term storage
If it is likely that the DC motors will be in storage for longer than 6 months or transported by sea and
then subsequently stored for longer than 3 months, the system manufacturer must fit safety guards be-
tween the collector and the carbon brushes.
Grinding the collector
Once the units reach their installation site, the layer of oxide on the collector’s bearing surface must be
ground away with a corundum stone (“fine”) or a carbon brush. Do not grind away more material than
is absolutely necessary.
Draw off or blow away all traces of grinding dust.
Notice! - Do not use abrasive cloths.
These will smooth the disks and damage the collector even before it has been put into operation.
