9 Mechanical Installation Considerations

9.1 Storage

Store the drive in a dry location. Keep the equipment
sealed in its packaging until installation. Refer to
chapter 7.5 Ambient Conditions for recommended ambient
temperature.
Periodic forming (capacitor charging) is not necessary
during storage unless storage exceeds 12 months.

9.2 Lifting the Unit

Always lift the drive using the dedicated lifting eyes. To
avoid bending the lifting holes, use a bar.
WARNING
RISK OF INJURY OR DEATH
Follow local safety regulations for lifting heavy weights.
Failure to follow recommendations and local safety
regulations can result in death or serious injury.

•
Ensure that the lifting equipment is in proper
working condition.
•
See chapter 4 Product Overview for the weight
of the different enclosure sizes.
•
Maximum diameter for bar: 20 mm (0.8 in).
•
The angle from the top of the drive to the
lifting cable: 60° or greater.

9.3 Operating Environment

In environments with airborne liquids, particles, or
corrosive gases, ensure that the IP/Type rating of the
equipment matches the installation environment. For
specifications regarding ambient conditions, see
chapter 7.5 Ambient Conditions.
NOTICE
CONDENSATION
Moisture can condense on the electronic components
and cause short circuits. Avoid installation in areas
subject to frost. Install an optional space heater when
the drive is colder than the ambient air. Operating in
standby mode reduces the risk of condensation as long
as the power dissipation keeps the circuitry free of
moisture.
NOTICE
EXTREME AMBIENT CONDITIONS
Hot or cold temperatures compromise unit performance
and longevity.

9.3.1 Gases
Aggressive gases, such as hydrogen sulphide, chlorine, or
ammonia can damage the electrical and mechanical
components. The unit uses conformal-coated circuit boards
to reduce the effects of aggressive gases. For conformal-
coating class specifications and ratings, see
chapter 7.5 Ambient Conditions.
9.3.2 Dust
When installing the drive in dusty environments, pay
attention to the following:
Periodic maintenance
When dust accumulates on electronic components, it acts
as a layer of insulation. This layer reduces the cooling
capacity of the components, and the components become

Do not operate in environments where the
ambient temperature exceeds 55 °C (131 °F).
The drive can operate at temperatures down to
-10 °C (14 °F). However, proper operation at
rated load is only guaranteed at 0 °C (32 °F) or
higher.
If temperature exceeds ambient temperature
limits, extra air conditioning of the cabinet or
installation site is required.
