Mechanical installation
Electric welding
It is not recommended to fasten the cabinet by welding.
Cabinets without flat bars at the base
• Connect the return conductor of the welding equipment to the cabinet frame at
the bottom within 0.5 m (20 in) of the welding point.
Cabinets with flat bars at the base
• Weld only the flat bar under the cabinet, never the cabinet frame itself.
• Clamp the welding electrode onto the flat bar about to be welded or onto the floor
within 0.5 m (20 in) of the welding point.
WARNING!
If the welding return wire is connected improperly, the welding circuit
may damage electronic circuits in the cabinet. The thickness of the zinc coating of
the cabinet frame is 100 to 200 micrometers (3.9 to 7.9 mil); on the flat bars the
coating is approximately 20 micrometers (0.8 mil). Ensure that the welding fumes
are not inhaled.
