Start-up and operation
Observe the safety instructions in chap. Safety, from page 5 on.
Please refer to chap. Technical data, page 7 for permissible operating
conditions.
When commissioning the NED, the rules and regulations of the local
associations for electrical engineering (e.g. VDE) and the valid accident
prevention regulations must be observed.
The NED must always be switched on and off at the main switch.
The NED must not be operated without the covers for the unbalances.
The rotating unbalances cause a risk of injury.
On initial start-up, the current consumption must be measured and
must correspond to the specifications on the type plate.
The terminal box cover must never be opened in the presence of volt-
age.
Note that the models NED 50100 up to NED 601510 have a start delay of
approx. 1 second
Carry out the following measures before start-up:
1.
Check that the NED have been mounted correctly and are in perfect
condition.
2.
Check that the NED have been properly connected.
3.
Check that the cables are undamaged and laid according to the
known regulations and standards.
4.
Check that all permissible operating conditions have been observed.
5.
Check that all protective measures on the system have been ob-
served.
6.
Eliminate possible errors before start-up.
7.
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 7
