Grounding the structure and fixation of the structure to the floor
GRD01
At least every second column of a display wall has to be grounded! The connection
of the grounding wire to the power net of the building has to be done by a qualified
electrician of the customer!
The grounding kit R764734 comprises the green-yellow grounding cable (5m), the necessary fixation
material and the label.
The grounding kit includes a nippled hammer b olt which digs into the profile. In
addtion, the contact washer also has pins to provide proper contact.
The zinc plated nut is screwed about 10mm to the hammer bolt.
Grounding is done on the rear side of the structure. The grounding wire is mounted to the right vertical
profile of each column (in case of the Atlas C4 systems, on the shared vertical profile).
•
To ground a column, proceed as follows:
•
Arrange the fixation material in the correct order.
•
Unscrew the nut from the hammer bolt.
•
Insert the contact washer, pin side to hammer bolt head.
•
Subsequently insert the annular cable lug, then the plain washer.
•
Loosely attach the nut.
•
Insert the pre-assembled hammer bolt into the right vertical profile, turn it, and fix it in a distance of
approx. 13cm measured from the floor.
Make sure to tighten it fast to provide proper grounding!
•
Attach the grounding label about 20mm above the connection point.
