●
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.
●
For frame size FSE inverters, use only cables certified for temperatures of 75° C to
connect the braking resistor.
●
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 with respect to ground), 480 V (phase to phase) for 400 V inverters
●
Terminal voltage, V
PR
= 2000 V
●
Suitable for SPD applications, type 1 or type 2
Alternatively, use a surge protection device, article number 5SD7 424-1 from Siemens AG.
Additional requirements relating to CSA conformance, frame sizes FSD … FSF
Overvoltage category OVC III must be ensured for all connections of the power circuit. This
can mean that a surge suppressor must connected upstream on the line side. The rated
voltage of the surge suppressor must not exceed the line voltage, and must guarantee the
limit values (VPR) specified here.
