swing. This can result in death, serious injury, or material damage.
•Use additional, suitable lifting equipment for transport and during installation.
•Two cables alone must be able to carry the complete load.
•Prevent the lifting equipment from sliding by appropriately securing it.
WARNING
Toppling over or slipping of the motor
The motor can slide or topple over if it is not correctly lifted or transported. This can
result in death, serious injury, or material damage.
•Use all the lifting eyes on the machine.
•When using the lifting eyes on the machine, do not attach any additional loads
or weight. The lifting eyes are only designed for the weight of the machine itself.
•Any eyes that are screwed in must be tightly fastened.
•Eyebolts must be screwed in right up to their supporting surface.
•Comply with the permissible eyebolt loads.
•When necessary, use suitably dimensioned transport equipment, for example
hoisting straps (EN1492-1) and load restraints (EN12195-2).
Note

56100000002002, 01/2016 91
4.4.1 Storage
Storing outdoors
NOTICE
Damage to the motor
Damage can occur if incorrectly stored.
Take all precautions to protect the motor under extreme climatic conditions, e.g.
salt-laden and/or dusty, moist/humid atmospheres.
Choose a dry storage location which is safe from flooding and free from vibration.
Repair any damage to the packaging before putting the equipment into storage if this
is necessary to ensure proper storage conditions. In order to ensure protection
against ground moisture, locate machines, equipment and crates on pallets, wooden
beams or foundations. Prevent equipment from sinking into the ground. Do not
impede air circulation under the stored items.
Covers or tarpaulins used to protect the equipment against the weather must not
come into contact with the surfaces of the equipment. Use wooden spacer elements
to ensure that air can circulate freely around the equipment.
Storing indoors
The storage rooms must provide protection against extreme weather conditions.
They must be dry, free from dust, frost and vibration and well ventilated.
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges)
should be coated with an anti-corrosion agent which will last for a limited amount of
time (<6 months). Apply suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the
environmental conditions, every six months at the latest.

Preparing for use
Explosion-protected machines
92 56100000002002, 01/2016
4.5 Explosion hazard during commissioning, if
stored incorrectly
WARNING
Risk of explosion due to damaged sealing materials
Storing the machine at temperatures that do not fall within the specified limits can
damage the material of the seals and cause them to fail. As a result, a potentially
explosive gaseous atmosphere can enter the machine and be ignited during
commissioning. Explosions can occur. This can result in death, serious injury or
material damage.
The materials used are specially designed for the temperature range required by
the customer. Do not store the motor in conditions that lie outside the specified
temperature limits. The relevant temperature limits are specified on the rating plate.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
The relative humidity of the air should be less than 60 %.
For machines that have a special design regarding the coolant temperature in the
operating state or the installation altitude, other conditions could apply regarding the
storage temperature. In this case, refer to the machine rating plate for data on the
coolant temperature and installation altitude.
Storage time
Turn the shafts 1x every year to avoid bearing brinelling. Prolonged storage periods
reduce the useful life of the bearing grease (aging).
Open bearings
●For open bearings, e.g. 1Z, check the status of the grease when stored for longer
than 12 months.
●Replace the grease if it is identified that the grease has lost its lubricating
properties or is polluted. The consistency of the grease will change if
condensation is allowed to enter.
