Cleaning and greasing
the flanges
➭ Clean all horizontal flanges of the busbar housings and the grooves for the sealing rings
carefully with lint-free paper.
➭ Carefully check the external contact surfaces of the flanges and the grooves for scratches
and other damages or pollution. Damages and pollution will cause leaks.
➭ If any external contact surfaces or grooves are damaged: Inform the regional Siemens
representative and coordinate the elimination of damages.
➭ Apply a uniform film of the supplied mounting paste to the flanges and O-rings (sealing
rings). To do this, apply a grease strip of approx. 3 mm thickness on the external contact
surface of the flanges. Use the supplied Polylub GLY 801 mounting paste only.
➭ Lay the O-rings into the grooves of the flanges.
