EU countries only – power line filter module installation
To enable regulator compliance with the European Union (EU) directives, a power line filter
module must be installed on the DC side of the power supply. This module may be ordered from
Cambium Networks (part number N000000L056A).
Procedure 11 Installing the power line filter (EU only)
1
Ensure that all equipment is disconnected from main power.

The filter may be mounted inside the CMM4 enclosure on the
upper shelf using two #6 pan-head screws, 3/8” long. (Top shelf
must be removed to complete this operation). Ensure that no
metal burrs are resident on the CMM circuit board after attaching
the filter to the top shelf. As an alternateive, adhesive-backed
industrialized Velcro (for example, 3M Scotchmate MP-3526N/27N
series) may be utilized to secure the filter (not included).
