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 Power Modules fulfill degree of protection IP20.
● 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:
Inverters 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.
● The inverters provide internal motor protection corresponding to UL61800-5-1. The
protection threshold is 115 % of the inverter full load current. When commissioning, you
can adapt the motor overload protection using parameter p0640.
● For frame size FSF, to connect the line supply and motor only use UL approved ring-type
cable lugs (ZMVV), which are certified for the particular voltage, with a permissible current
of at least 125 % of the input and output current. Use the higher value as basis.
● Carefully note that for plants and systems in conformance with UL/cUL, the line and output
voltage may not be higher than 600 V.
● Only use copper cables rated for 60 °C or 75 °C.
