Installation
12
• Maximum motor cable length for NOCH0xxx-6x filters (cumulative for several
parallel-connected motors):
• The filters cool by natural convection. The air space above the filter is hot (up to
70 °C (158 °F) depending on the installation and operating conditions). Take this
into account in the cabinet design.
• The following free space requirements apply for the AOCH0xxx-70 filters:
150 mm free space on each free side. Exception: 500 mm above the filter if
installed below the drive. Exception: 50 mm between the single phase filters
which are connected to the same drive.
If filters are mounted on top of each other with single drive types 0320-5,
0610-5 and 0610-7, the filters need a minimum of 700 m
3
/h of forced cooling.
Maximum of three filters can be mounted on top of each other.
