3. Installation
ATTENTION
•
Environmental influences such as high temperatures and high relative humidity are to be avoided as
well as dust, dirt and corrosive gases. The mounting location should be well ventilated and not
exposed to direct sunlight. Install the device on a non-flammable, vertical wall that does not transmit
any vibrations. Attention! Do not apply mains voltage to the output terminals U/T1, V/T2 and W/T3.
For heat convection reasons the Bulletin 161 drive must be installed vertically. Observe the specified minimum
distances to the side walls or other devices. Objects that come into contact with the inside of the drive may
result in the device being damaged.
If installed in normal environmental conditions (max. 40°C ambient) there must be a minimum of 20 mm
clearance around all sides of the drive to enable the user or installer to open the front cover to get access to the
terminals.
The figure below shows the minimum required clearances in case the Bulletin 161 is installed in an IP54
enclosure.
When carrying out work on the Bulletin 161 drive please ensure that no objects such as cable insulation, metal
filings or dust get into the enclosure. This can be avoided by covering up the non-energized AC drive.
Temperatures may not exceed or go below the permissible temperature range from -10 to +40°C (or to +50°C
in the following cases: reduction of the reference frequency to 2 kHz; reduction of the output current to 80%
Bulletin 161 drive rated current; removal of the top cover). The higher the ambient temperature, the shorter the
life of the drive.
Do not install the device in the vicinity of devices that radiate heat.
If installing the device in a control cabinet, pay attention to the size and heat transfer capability of the control
cabinet. A fan may have to be installed.
