5 Mechanical Installation
5.1 Storing the Enclosed Drive
5.1.1 Storage Requirements
If it is necessary to store the product before installing it, follow these instructions.
Keep the product in the original packaging. Make sure that the ambient storage conditions correspond to these requirements:
l Temperature: -40...+70 °C (-40...+158 °F)
l Humidity: 0...95%, no condensation
5.1.2 Storage of 2–12 Months
If the package is kept in storage for more than 2 months, keep it in controlled conditions.
1. Make sure that the temperature variation is small.
2. Make sure that the humidity is less than 50%.
5.1.3 Storage of over 12 Months (FE9 and FE10)
If the package is kept in storage for more than 12 months, do these steps every 12 months, to reform the capacitors to prevent damage
to the capacitors.
1. Connect power to the drive.
2. Keep the power on for a minimum of 2 hours.
3. Disconnect the power.
4. Wait for the correct discharge time before removing the drive and storing it again.
5.1.4 Storage of Several Years
If the package is kept in storage for several years, reform the capacitors every 12 months to prevent damage to the capacitors.
1. Connect a DC supply with adjustable current limit to the DC+ and DC- terminals.
2. Set the current limit (250 mA). In case of parallel power units, multiply the value with the number of power units.
3. Set DC voltage (1.35 x U
n
AC), where U
n
is the drive nominal voltage.
4. Keep the power on for a minimum of 1 hour.
5. Disconnect the DC supply from the DC+ and DC- terminals.
5.2 Installation Requirements
l Make sure that the ambient conditions at the installation location comply with the specifications in
9.8.3 Ambient Conditions.
l Install the drive on a solid and level surface.
l Make sure that the mounting surface can support the weight of the drive. See
4.4 Weights.
l Make sure that the mounting surface is non-combustible.
5.3 Installing the Enclosed Drive
1. Secure the enclosed drive to the floor and to the wall using all the mounting holes.
There are 2 mounting holes at the rear top, 6 mounting holes at the front bottom, and 6 mounting holes at the rear bottom.
