• An overcurrent protection device must be fitted as a disconnecting device in all supply lines but must not interrupt the pro-
tective conductor. If fuses are used, all must have the same rated value and the same tripping characteristics and must be
installed side by side. They are preferably to be placed before the power switch. Radio interference control equipment
between the AC input and overcurrent protection device is allowed. Fuses and single-pole circuit breakers are not built into
the neutral conductor of multi-phase devices.
If the above-cited isolating devices are already in the system, these no longer need to be provided by the operator for the system.
Please see the chapter ‘Technical Data’ for the applicable values of the isolating devices.
