Mechanical Installation Considerations
5.1
Storing the System Module
If it is necessary to store the product before installing it, follow these instructions. Keep the equipment sealed in its packaging until
installation.
1.
Make sure that the ambient conditions correspond to these:
Temperature: -40...+70 °C (-40...+158°F)
Humidity: 0...95%, no condensation
2.
If the package is kept in storage for more than 2 months, keep it in controlled conditions.
a.
Make sure that the temperature variation is small.
b.
Make sure that the humidity is less than 50%.
3.
If the package is kept in storage for more than 12 months, connect power to the drive.
a.
Connect power to the drive.
b.
Keep the power on for a minimum of 2 hours.
c.
Disconnect the power.
d.
Wait for the correct discharge time before removing the drive and storing it again.
4.
If the package is kept in storage for several years, reform the capacitors to prevent damage to the capacitors.
a.
Connect a DC supply with adjustable current limit to the DC+ and DC- terminals.
b.
Set the current limit (250 mA). If there are parallel power units, multiply the value with the number of power units.
c.
Set DC voltage (1.35 * U
n
AC), where U
n
is the drive nominal voltage.
d.
Keep the power on for a minimum of 1 hour.
e.
Disconnect the DC supply from the DC+ and DC- terminals.
5.2
Requirements for the Cabinet
The system modules that are described in this guide have the protection rating IP00/Open Type and do not have an enclosure. They
must be installed in a cabinet or other enclosure that has a correct level of protection against the ambient conditions in the installation
area. Make sure that the cabinet gives protection against water, humidity, dust, and other contaminations. The protection rating of the
cabinet must be at least IP21/UL Type 1. The mounting surface of the cabinet must be non-combustible.
The cabinet must also be sufficiently strong to carry the weight of the system module and other devices. It is recommended to use a free-
standing, floor-mounted cabinet made of sheet metal.
The maximum temperature of the air inside the cabinet is +60 °C (+140 °F).
When preparing the installation, obey the local regulations.
5.3
Installation Direction
The system modules can be installed in different directions.
NOTICE
The inverter modules (IM11 and IR11) use a heat pipe technology that limits the installation direction. The heat pipes rely on
gravitation, thus do not operate fully in certain orientations. Do not install the inverter module on its right side.
