DANGER
Life-threatening danger due to electric shock
Circuit breaker systems that are not connected or attached incorrectly can generate hazardous voltages
and electric shock and cause severe accidents.
 Work on electrical connections must be carried out exclusively by trained, qualified electricians.
 Circuit breakers systems must be provided in accordance with DIN EN 60204-1, chapter 8.2.
 Each element of electrical equipment must be connected to the circuit breaker system.
 Never interrupt the circuit breaker system if electrical equipment is attached to covers, doors or cover
panels.
 If parts are removed, e.g. for maintenance work, ensure that the circuit breaker system is not
interrupted for the remaining parts.
