ATTENTION
Motor should only be lifted by the
eyebolts. These eyebolts have been
designed to hold motor weight only.
So avoid lifting additional loads.
Special care should be taken with the motor
package so as to avoid any damage to it.

removal.
RECEIVING INSPECTION
When receiving the motor, check if any damage has
occurred during transportation. Then remove the
shaft locking device and keep it in a safe room once
it needs to be used on future transportation.
If anything has been noticed, notify immediately the
carrier, the insurance company and WEG.
EX ATMOSPHERE INFORMATION
Failure in giving notice to the carrier,
to the insurance company and to
WEG may result in loosing the
warranty.
When lifting the boxes, it is important to observe the
appropriate locals for this purpose as well as to
check the weight of the box and the hoist capacity.
The motors shipped in wooden boxes must be
always lifted by the eyebolts or by forklift machines
and never by the shaft. The box must never be
turned around. Lifting and lowering of such boxes
must be done gently in order to avoid damage to the
bearings.
After being removed from the package, a complete
visual inspection on the motor should be made.
Do not remove the existing protecting grease from
the shaft end, nor the stoppers or plugs that close
the terminal box holes, if any. These protection
items must be kept in place until the final installation
has been concluded.
For motors supplied with roller bearings, shaft
should be rotated manually a few times for a uniform
grease distribution.
ATTENTION
To ensure the degree of protection,
the connection box should be kept
closed. Before energise the motor,
check the cleanliness and moisture
condition inside of the terminal box.

STORAGE
INDOOR STORAGE
When motors are not unpacked immediately after
receiving, they should be maintained in places
protected from humidity, vapors, sudden heat
changes and rodents. To avoid bearing damage,
motor should also be storage in places free of
vibrations. Any painting damage and protecting
grease absent areas should be fixed so as to avoid
future rusting.
For maintenance purposes, please refer to Table
3-4.
OUTDOOR STORAGE
A dry storage location, safe from flooding, dust-free
and free from vibrations, should be choosen. Repair
any damage to the packing before putting the
equipment in storage to ensure proper storage
conditions. Position machines, devices and crates
on pallets, wooden beams or foundations that
guarantee protection against ground dampness. It
also prevents the equipment from sinking into the
ground and allows the circulation of air underneath
the equipment.
Covers or tarpaulins used to protect the equipment
against the weather must not make contact with the
surfaces of the equipment. Ensure adequate air
circulation by positioning wooden spacer blocks
between the equipment and such covers.
For maintenance purposes, please refer to Table
3-5.
