DANGER
Danger of electric voltage!
Products with extraction power control (frequency inverters) are
intended for protection by line protection fuses.
If the product is operated on a mains supply with a residual current
circuit breaker (RCCB) connected upstream, the following must be
observed.
Since the operation of the frequency inverter on the protective earth
conductor can cause a direct current, the residual current circuit breaker
(RCCB) connected in series with the mains must meet the following
requirements.
