Choose a location away from sources of dust, debris
or construction activities which may cause impact or
damage to the assembly or its components.
Ensure all components are covered with at least two
layers of plastic:
Secure plastic in case of strong winds.
Ensure drainage exists within the plastic envelope.
Form a sloped surface to prevent the pooling of water,
snow, or debris.
Protect all machined surfaces with anti-rust coating.
Ensure space heaters are energized.
Place the motor on platforms or foundations which ensure
protection against land humidity and keep the motor
from sinking into the soil. Free air circulation underneath
the motor must be assured.
ATTENTION
Never place the motor or any sub-
assemblies directly on the ground.
Always use wooden or other
appropriate blocking.
6.4 LONG-TERM STORAGE
If the unit is to be stored for more than thirty (30) days prior
to installation, the instructions below must be followed. In
addition, if a unit is to be decommissioned or removed from
service for maintenance, overhaul, or repair, the instructions
below should also be followed.
6.4.1 General Guidelines
It is critical during long-term storage to protect the critical
features of the unit (windings, bearing surfaces, and
electrical connections) to prevent the need for costly repairs
not covered by warranty. It is the responsibility of the end
user to ensure that the motor is stored in a location which
will not subject it to any contamination, vibration, extreme
temperatures, or other conditions which may have a
negative impact on the lift of the unit.
In general, a well-covered unit with energized space
heaters stored in a dry area, free from strong winds or
other environmental factors will not suffer significant
deterioration during long-term storage. It is impossible to
predict all possible sources of contamination at a particular
site, and it is strongly recommended to have WEG Electric
Machinery Field Engineering support when organizing and
implementing a long-term storage plan.
ATTENTION
To ensure compliance with warranty,
all long-term storage procedures
must be followed and documented
by the end user.
6.4.2 Storage Location
In order to ensure the best storage conditions for the motor
during long periods of time, the chosen location must strictly
meet the following criteria described.
6.4.2.1 Long-Term Indoor Storage
The storage location must include a fully-intact roof.
The storage location must be protected against high
humidity, harmful vapors, rapid changes in temperature,
rodents and insects.
Corrosive gases such as Chlorine, Sulfur Dioxide or acid
must not present.
The storage location must be free from any vibration.
The storage location must include filtered incoming air.
The storage location ambient temperature must be
between 0°C and 40°C (32°F and 100°F).
The storage location relative air humidity must be below
50%. If this is not possible, the unit must be completely
covered and the space heaters fully-energized to prevent
moisture ingress.
The storage location must be clean.
The storage location must have a fire detection system.
The storage location must include a reliable electrical
supply for space heaters and monitoring using a light or
other easily visible means.
If one or more of the requirements above cannot be met,
it is required that additional protection, such as wooden
crating, external heat sources, or third-party storage be
used to protect the integrity of the unit. Contact WEG
Electric Machinery to review the long-term storage plan.
6.4.2.2 Long-Term Outdoor Storage
ATTENTION
Long-term outdoor storage of
motors is not recommended.
If outdoor storage cannot be avoided, the motor should be
well-protected for the local conditions as described below.
The unit must be placed well off the ground on heavy
wood or other blocking.
The unit must be placed on stable ground, where flooding,
sinking, blowing snow or dust will not contaminate or
damage the unit.
An adequate shelter of wood and multiple layers of
plastic must be constructed to protect the exterior of the
unit during storage and this structure should be designed
to shed rain and snow as well as protect the unit from
contamination and excessive changes in temperature.
Insulating tarpaulins used for concrete insulation may be
required to thermally insulate the unit.
The space heaters must be energized and a visible
means of inspection the condition of the circuit such as a
light bulb must be used.
Ensure bearing protective paper is in place prior to lifting
(if applicable).
