We recommend that you use the optional mounting frames when installing PT Power
Modules in a control cabinet. This mounting frame includes the necessary seals and frame to
ensure compliance with degree of protection IP54.
If you do not use the optional mounting frames, then you must ensure that the required
degree of protection is complied with using other appropriate measures.
