3.3 Assembly
The installation guidance provided here takes into account building the
devices into suitable housing with degree of protection IP20 in accordance
with standard EN 60529 or other essential provisionsthat apply regionally.
•
The enclosures must be made of a material with high thermal conducti-
vity.
•
If a control panel with ventilation openings is used, the openings must
be located above and below the variable frequency drive in order to allow
for proper air circulation. Air should enter from the bottom and be
expelled through the top.
•
If the environment outside the control panel contains dirt particles
(e.g. dust), a suitable particle filter must be placed on the ventilation
openings and forced ventilation must be used.
The filters must be maintained and cleaned as necessary.
•
An appropriate enclosed control panel (without ventilation openings)
must be used in environments containing high levels of humidity, salt,
or chemicals.
3.3.1 Installation position
The DB1 variable frequency drive range can be built in where desired.
In doing so, you must ensure that the cooling system used in the installation
position is capable of removing lost heat without this causing the permitted
temperature on the variable frequency drive cooling surface to be exceeded.
