4.1 Installation conditions
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
● Suitable for SPD applications, type 1 or type 2
Alternatively, use a surge protection device, article number 5SD7 424-1 from Siemens AG.
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.
