Information on the assembly is available on the website http://www.abb.com/abblibrary/DownloadCenter/, in
particular in the kit sheet 1SDH001000R0746 for fixed circuit-breakers and in the kit sheet 1SDH001000R0747
for withdrawable circuit breakers.
Grounding
The circuit-breakers in fixed version and the fixed part of withdrawable circuit-breakers are equipped with a
screw for the ground connection.
The connection must be implemented by means of a conductor of suitable cross-section according to the
IEC 61439-1 Standard.
Clean and degrease the area around the screw before making the connection.
After assembly of the conductor, tighten the screw with a torque of 2 Nm - 17.7 lb in.
