4. Components of the DSO cabinet.
The equipment of each DSO cabinet includes the elements necessary for the proper operation of the
system. These components, depending on their intended use, protect the electrical system against overvoltage or
short circuit, supply power to the receivers, and ensure proper signaling or cooling of the installed equipment in the
RACK cabinet.
If the device comes in several models, they are selected automatically by the CONFI-DSO program
supporting the DSO configuration.
4.1. The LZxxxx safety strip.
Safety strip is fitted with circuit breakers, surge arresters, and a dummy connector.
The main overcurrent circuit breaker disconnects the 230V/400V mains from all system devices. In
addition, the power supply circuit is fitted with an overcurrent circuit breaker allowing its disconnection, e.g. for
maintenance purposes, without disconnecting other devices of the DSO. In addition to the main switch, it is fitted
with "type 3" surge arresters compliant with the EN 61643-11 standard.
The dummy connector includes overcurrent circuit breaker which can be switched on regardless of the
status of the main switch.
