Alarms and failures can be transmitted to a superordinate position (building control
technology or permanently manned location) via potential-free contacts, the Moni-
toring System CMC, the IoT interface or via the Power Distribution Unit PDU (Rittal
products).
Network capability is established with one of the mentioned Rittal products.
The compact system with a space requirement of only one rack unit is intended for
installation in the upper third of the closed 19" cabinet to be protected.
