Line protection and earth-leakage circuit breaker

• Install fuses at the beginning of the mains cable behind supply bus junction (see basic unit wiring diagram).
• SEW-EURODRIVE recommends that you do not use RCDs. However, if an earth-leakage circuit breaker is stipulated for direct or indirect protection against contact, observe the following:
• WARNING Wrong type of earth-leakage circuit breaker installed.
• Severe or fatal injuries
• MOVITRAC^® can cause direct current in the PE conductor. If a residual current device (RCD) or a residual current monitoring device (RCM) is used for protection in the event of a direct or indirect contact, only a type B RCD or RCM is permitted on the supply end of the MOVITRAC^®.
