Observe the following when performing any work on the terminal box:
▪
Always use the original seal to close the terminal box so that it is dust- and
watertight.
▪
Do not damage components on the inside of the terminal box (e.g. terminal
board and cable connections).
▪
Ensure that no foreign bodies, contamination or moisture are present in the
terminal box. Terminal box cable entries to DIN 42925.
▪
Close additional open cable entries using O-rings or suitable gaskets.
▪ Observe prescribed tightening torques for cable glands and other screws/bolts.
▪ Secure keys for test runs without output elements.
▪ When retrofitting cable glands to safeguard the required level of enclosure
protection, ensure that the gasket is seated properly on the outside of the
terminal box.
NOTE
To establish a connection, only use the connecting cables included in the KSB
adapter kit with the conductor cross-section area required. If other cables are to be
fitted to establish a connection to the motor terminal board, always use cable lugs
that are compatible with the conductor cross-section and bolt size.
