Installation conditions

General installation conditions
When installing the Power Modules carefully observe the conditions listed below in order to
guarantee reliable, continuous and disturbance-free operation.
● The Power Modules are designed for installation in a control cabinet.
● The Power Modules are certified for use in environments with degree of pollution 2
without condensation; i.e. in environments where no conductive pollution/dirt occurs.
● The built-in units fulfill IP20 degree of protection at delivery status with the maximum
cross section for the connected cables.
● Fast temperature changes of the air drawn in (e.g. by using cooling units) are not
permitted due to the risk of condensation.
● Condensation is not permissible when switching on.
● You can find the permissible conductor cross-sections for the terminals in:
● The following section describes how you can install the Power Module in compliance with
EMC regulations:
● Devices in push-through technology – PT devices
– PT devices have IP20 degree of protection and at the rear of the control cabinet they
– PT devices, FSF: A pressure compensation valve is necessary for the cabinet in order
● For a system configuration in conformance with IEC, use the fuse types approved for IEC,
specified in the Technical data, or the circuit breakers under the following Internet
address.
