4.1 Installation conditions
● 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.
● FSE, IP20: Only use cables that are certified for temperatures of 75 °C to connect the
braking resistor.
● FSE, PT: Only use cables that are certified for temperatures of 75 °C to connect the line
supply, motor and braking resistor.
● The inverters are Open Type devices.
● The push-through FSD ... FSF inverters are Open Type devices. At the rear of the control
cabinet they fulfil Enclosure Type 1.
● The DC-link terminals, DCP and DCN, were not investigated regarding conformance with
UL/cUL.
Additional requirements for CSA compliance, frame sizes FSA ... FSC
Install the inverter with an external suppression device with the following properties:
● Surge protection device with the appropriate certification (category checking numbers
VZCA and VZCA7)
● Rated supply voltage
– 240 V (phase with respect to ground), 240 V (phase to phase) for 200 V inverters
– 480 V (phase to phase) for 400 V inverters
● Terminal voltage, V
– max. 2000 V for 200 V inverters
– max. 2500 V for 400 V inverters
● Overvoltage category III
● Pollution degree 2
● Suitable for SPD applications, type 1 or type 2
Alternatively, use a surge protection device, article number 5SD7 424-1 from Siemens AG.
