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.
● You can find the permissible conductor cross-sections for the terminals in:
● The following section describes how you can install the Power Modules in compliance
with EMC regulations:
● 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.
–
–
Converters for systems in the United States / Canada (UL/cUL)
● For a system configuration in conformance with UL/cUL, use the fuse types approved for
UL/cUL, specified in the Technical data, or the circuit breakers under the following
Internet address.

–
● The integrated semiconductor short-circuit protection does not provide cable protection.
● On the system side, provide cable protection in conformance with NEC or CEC, Part 1
and the local regulations.
