Notice: The feet of the NEG/NEH must lie completely on the surface
so that there is no tension in the housing when tightening the fas-
tening screw/screws, which could cause mechanical damage.
For NEH the bracket NVH 1 / NVH 4 must be welded over the entire
surface of the structure to be vibrated.
The mounting surface has to be flat (for NEG: ±0.1 mm flatness), and
clean with no paint residues or burn-ins.
Fastening depending on vibrator type:
•
Mount the NEG with fastening screws of quality 8.8 (DIN 931

NBS-fastening kits.
•
Mount the NEH onto the bracket NVH 1 / NVH 4 with the sup-

Use a torque wrench and observe the recommended values for bolt
sizes and tightening torques in chap. Technical data, from page 9.
Higher tightening torques can cause the screws/nuts to break or the
threads to tear out.
Warning: Unsuitable screw connections may cause loosening of the
NEG/NEH by vibration. This can cause damage to persons and mate-
rial.
In critical installation situations, use addi-
tional protection against falling down, e.g.
steel cable NSE.
