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 Module is designed for installation in a control cabinet.
● The Power Module is certified for use in environments with degree of pollution 2 without
condensation; i.e. in environments where no conductive pollution/dirt occurs.
Condensation is not permissible.
● The Power Modules fulfill degree of protection IP20.
● Permissible cross-sections for terminals:
torques (Page 68) .
● EMC-compliant installation:
Inverters for systems in the United States / Canada (UL/cUL)
● For configurations in conformance with UL/cUL, use the UL/cUL-approved fuses, Class J
or Siemens 3NE1 semiconductor fuses, which are specified in this manual.
Fuse types and characteristic values are described in the following sections:
● Only use copper cables rated for 60°C or 75°C. For frame sizes FSE, only use cables
that are certified for temperatures of 75 °C to connect the braking resistor.
● For frame size FSF, to connect line and motors only use 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.
● 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.
● Carefully note that for plants and systems in conformance with UL/cUL, the line and
output voltage may not be higher than 600 V.
● The DC link terminals, DCP and DCN, were not investigated regarding conformance with
UL/cUL.
