MX15 65
3.14 Output Filter Box Accessory
An optional output filter box (P/N 7003-424-1) is available which may be used reduce the amount
of ripple and noise present at the output of the MX15-3Pi.
The filter must be connected between the single-phase output of the MX15 and the unit under
test. To access the connection terminal blocks, the top cover of the filter case must be removed.
Note: Make sure all power is off when connecting the filter accessory.
The output of the MX15 is connected to the input side of the filter. Use terminal blocks TB1A
(phases A and B) and TB1B (phase C and neutral) as indicated in Figure 3-17. For MX15
application, only phase A and Neutral connection will be made. The load can be connected to
the load side of the filter box using terminal blocks TB2A and TB2B. Do not swap phases through
the filter.
To compensate for voltage drop across the filter, the external sense connections can be made at
the load (load side of the filter).
Note: The filter box chassis must be connected to earth ground.
It is not recommended to use the ground connection on the MX15 itself for this purpose but
rather a ground point at the AC service to the MX15.
