3.4.1 General assembly requirements
Switch cabinet installation hazard due to assembly chips
When making the cooling unit cut-outs, assembly chips can fall into the switch cabinet.
When assembling the switch cabinet, protect against contaminants and use protective covers.
The following general requirements must be followed for safe and reliable operation of the cooling units:
The place where the switch cabinet is mounted must be selected so as to guarantee adequate ventilation of the
cooling unit. A minimum clearance of 200 mm between units and from the nearest wall must be observed.
Installed components in the switch cabinet must not impede air circulation.
Secure the switch cabinet against tipping.
Ensure that provided hinges can support the additional weight of the cooling unit.
Assembly of the cooling unit can take place with and without an external unit cover.
Protect the installation location from heavy contamination with covers.
