Grounding Connectors
All tangible surfaces of the 19-inch HIMA components (e.g., base racks, extension racks and
dummy front plates) are chromized and electrically conductive for ESD protection reasons.
Safe electrical connection between components and the control cabinet is ensured by cage nuts
with claw fasteners. The claw fasteners penetrate the surface of the pivoting frame [1], ensuring
safe electrical contact. Stainless steel screws and flat washers are used to prevent electrical
corrosion [2].
The components of the cabinet frame [3] are welded together and are considered an electrical
conductive construction element. Short grounding straps [5] with cross-sections of 16 mm

or
25 mm

are used to conductively connect the pivoting frames, door, mounting rails and
mounting plates to the cabinet frame.
