1)
Used only as an AC fuse. An external DC fuse must be used with DC supply.
2)
Internal limitation via a second control loop, deactivation of power supply, automatic restart
3)
The voltage must not be exceeded due to power feedback.
4)
Configurable; see section
8
“Latching Shutdown on Thermal Overload” Mode [
5)
The circuit breaker can be used for activation during installation. In this case, the circuit breaker must meet
all the requirements on this shutdown device. If an additional switch is used, it must have the same electrical
load capacity as the circuit breaker.
