Protecting the line voltage supply
To protect the line voltage supply, proceed as follows:
The feeder must be protected using an external overcurrent protection
device.
It must be possible to switch off the feeder using a separator (external
switch).
The separator must be located near the supplied device.
The way in which the supplied device is arranged must not compromise
the operation of the separator.
The isolator must be identified so that the assignment to the supplied
device is clearly visible.
Note the built-in fuses in the junction box.
