ABB ACSM1 Hardware Manual page 29

Arrange the cooling of the modules so that the requirements given in chapter
Technical data are met:
• cooling air flow
Note: See the values in
• allowed ambient temperature
• cold plate specification (for ACSM1-204Cx-xxxx-x only).
Make sure the air inlets and outlets are sufficient in size. Note that in addition to the
power loss of the regen supply module and the WFU-xx regen filter module, the heat
dissipated by cables and other additional equipment must also be ventilated.
The internal cooling fans of the modules are usually sufficient to keep the component
temperatures low enough in IP22 cabinets.
In IP54 cabinets, thick filter mats are used to prevent water splashes from entering
the cabinet. This entails the installation of additional cooling equipment, such as a
hot air exhaust fan.
The installation site must be sufficiently ventilated.
