Installation
Observe the safety instructions in Ch. Safety, from page 5 on.
Please refer to the brochure for weights and dimensions.
The NED can be operated in any position.
1.
Notice:
The feet of the NED must lie completely on the surface so that
there is no tension in the housing when tightening the fastening
screw/screws, which could cause mechanical damage. The mounting
surface has to be flat (±0.1 mm flatness) and clean with no paint resi-
dues or burn-ins.
2. 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
Netter
Vibration
recommends the use of fas-
tening kits NBS consisting of a screw, a special lock washer and (for
NBS D) a nut.
Fasten the NED with the fastening screws on the mounting surface.
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 7. Higher tightening torques may
cause fracture of screws or tearing of threads.
Warning:
Unsuitable screw connections may cause loosening of the
NED by vibration. This can cause damage to persons and material.
3. 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.
