DANGER!
Risk of fatal injury from electrical current!
When using an external ballast resistor, you must remove the wire bridge between
RBint and BA-. Otherwise, the ballast transistor is overloaded and destroyed.
ZK+, ZK- Connections for DC link
BUM 60: Connections for DC link
Discharging the DC Link capacitor takes at least one minute.
If necessary, the DC Link can be rapidly discharged via a resistor.
Connect an external ballast resistor between ZK+ and BA-.
If UL508C has to be observed:
The external ballast resistor must protect itself from overheating.
BUS 60: Connections for DC link power supply
DANGER!
Risk of fatal injury from electrical current!
Parallel switching several devices via the DC Link connections is not allowed. This
overloads the starting current limitation device and destroys it.
