6.3 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
specications regarding ambient conditions, see
chapter 5.4 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.
•
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.
6.3.1 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 eects of aggressive gases. For conformal-
coating class specications and ratings, see
chapter 5.4 Ambient Conditions.
6.3.2 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
warmer. The hotter environment decreases the life of the
electronic components.
Keep the heat sink and fans free from dust build-up. For
more service and maintenance information, refer to the
operating guide.
Cooling fans
Fans provide airow to cool the drive. When fans are
exposed to dusty environments, the dust can damage the
fan bearings and cause premature fan failure. Also, dust
can accumulate on fan blades causing an imbalance which
prevents the fans from properly cooling the unit.
6.4 Mounting Congurations
Table 6.1 lists the available mounting congurations for
each enclosure. For specic panel/wall mounting or
pedestal mounting installation instructions, see the
operating guide. See also chapter 5.8 Exterior and Terminal
Dimensions.
NOTICE
Improper mounting can result in overheating and
reduced performance.

panel-mounted inside an enclosure due to its protection rating.
Mounting considerations:
•
Locate the unit as near to the motor as possible.
See chapter 5.5 Cable Specications for the
maximum motor cable length.
•
Ensure unit stability by mounting the unit to a
solid surface.
•
Ensure that the strength of the mounting location
supports the unit weight.
•
Ensure that there is enough space around the
unit for proper cooling. Refer to chapter 3.5 Back-
channel Cooling Overview.
•
Ensure enough access to open the door.
•
Ensure cable entry from the bottom.
