6.3 Operating Environment
6.3.1 Operating Environment Overview
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 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.
l Do not operate in environments where the ambient temperature exceeds 55 °C (131 °F).
l 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.
l If temperature exceeds ambient temperature limits, extra air conditioning of the cabinet or installation site is required.
6.3.2 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 Ambient Conditions.
6.3.3 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.
Cooling fans
Fans provide airflow 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 Configurations
The following table lists the available mounting configurations for each enclosure size of the drive.
NOTICE
Improper mounting can result in overheating and reduced performance.
