Installation
Observe the safety instructions in Ch. Safety, from page 6 on.
Please refer to the brochure for weights and dimensions.
Important: For NEA/NEG with housing size 101 to 120 the terminal box is
Fastening
integrated in the housing foot. These vibrators must be electrically con-
the NEA/NEG
nected before fastening.
The NEA/NEG can be operated in any position.

Notice: The feet of the NEA/NEG 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. The
mounting surface has to be flat (±0.1 mm flatness) and clean with no
paint residues or burn-ins.
The vibrators can be fastened with fastening screws of quality 8.8
(DIN 931 or 933). These must be secured with appropriate locking de-
vices and checked and retightened at regular intervals (usually month-
ly). For safe fastening
tening kits NBS consisting of a screw, a special lock washer and (for
NBS D) a nut.
Fasten the NEA/NEG with the fastening screws on the mounting sur-
face. Use a torque wrench and tighten the screws crosswise. Observe
the recommended values for screw sizes and tightening torques, see
chap. Technical data, from page 11. Higher tightening torques may
cause fracture of screws or tearing of threads.
Warning: Unsuitable screw connections may cause loosening of the
NEA/NEG by vibration. This can cause damage to persons and mate-
rial.
Use an additional safety device for critical
installation situations, e.g. steel cable NSE.
Use the wire cable clamps to set the safety
cable to the shortest possible cable length.
The safety cable must always be ten-
sioned.
