4 Mechanical Installation
4.1 Tools Needed
• I-beam and hooks rated to lift the weight of the drive. Refer to the Power Ratings, Weights, and Dimensions section.
• Crane or other lifting aid to place the unit into position.
• Drill with 10 mm or 12-mm drill bits.
• Tape measurer.
• Various sizes of Phillips and flat bladed screwdrivers.
• Wrench with relevant metric sockets (7–17 mm).
• Wrench extensions.
• Torx drives (T25 and T50).
• Sheet metal punch for cable entry plate.
4.2 Storing the Drive
Store the drive in a dry location. Keep the equipment sealed in its packaging until installation. Refer to the Ambient Conditions section
for recommended ambient temperature.
Periodic forming (capacitor charging) is not necessary during storage unless storage exceeds 12 months.
4.3 Operating Environment
4.3.1 Overview
In environments with airborne liquids, particles, or corrosive gases, ensure that the IP/NEMA protection rating of the equipment
matches the installation environment. Refer to the Ambient Conditions section.
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 unit 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 unit 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. Also, temperature feedback is not shown when temperatures are below 0 °C (32 °F).
-
Provide extra air conditioning for the cabinet or installation site when the temperature exceeds ambient temperature limits.
