9. Potective devices
9.1 End-user protective devices
9.1.1 Earth leakage switch
The switch protects the user from unsafe situations related to the 230V
output.
It prevents the end user from being exposed to 230V, which can be deadly.
If there is a unwanted current leaking through the user’s body, the earth
leakage switch will interrupt the current.
9.1.2 Situation in an isolated environment (in a vehicle)
A standard earth leakage circuit breaker does not work in an isolated
environment in case of an insulation error. To prevent the shortcomings of
an earth leakage circuit breaker in this situation, an insulation monitor has
been installed in the Zeliox Compact.
9.1.3 Isolation monitor
In some cases, the earth leak switch cannot function, for example in the
field when the Zeliox Compact is not connected to the mains and the end
user is in the harness (vehicle/vessel). In that case, an isolation monitor is
required. The Zeliox Compact contains an insulation monitor and is only
active when the Zeliox Compact is not connected to the mains.
9.1.4 Fuses
The Zeliox Compact contains a number of fuses to prevent short circuits
and/or fires. If a fuse has melted, the Zeliox Compact will have to be
checked for damage. The fuses may only be replaced by the experts of
Zeliox®.
