NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
Variant 2 – use of an optional power supply SK xU4-24V-...
Since the permissible load of terminal 44 is limited to 60 mA when using the AS interface, if there is an
increased power requirement it is possible to incorporate a power supply (e.g. SK CU4-24V-...) for
supplying the additional peripherals. However, under no circumstances must the 24 V voltage of
the power supply be connected to the frequency inverter (see also following connection example).
