For overseas countries, also for countries within the EU, the mains volt-
age, the network configuration and the directives applicable there must
also be observed. In the case of deviations, the country, the standards, the
environmental conditions, as well as possible special features in the order,
must be agreed on in writing. If the NEA/NEG are operated and/or pow-
ered by another network configuration unknown to us, the guarantee ex-
pires completely and immediately.
Supply line
The supply line must be protected according to the cross-section and the
connection
nominal power of the NEA/NEG. The short circuit strength of this fuse
should be 25 kA.

Adjustment of
For all NEA/NEG there is the possibility of unbalance adjustment to direct-
unbalances
ly influence vibration amplitude, centrifugal force and current consumption.
Unless otherwise specified by you, the NEA/NEG were delivered with the
standard setting (100 %). If specifications have been made by the custom-
er, there are stickers with the current setting on the unbalance covers.
Notice: The unbalances may only be set mirror-symmetrically!

Check that the cables are undamaged and laid according to the
known regulations and standards.
Check that all permissible operating conditions have been observed.
Check that all protective measures on the system have been ob-
served.
Eliminate possible errors before start-up.
Screw connections must be checked and, if necessary, retightened
after 1 h operating time (after initial start-up) and thereafter regularly
(generally monthly). Observe the recommended values for screw siz-
es and tightening torques, see chap. Technical data, from page 11
