Mounting position changed
QUESTION:
Which technical consequences shall be considered if mounting position other than standard is used?
ANSWER:
Operating the contactor at other than standard mounting position is subject to following restrictions:
- drop out voltage of contactor is reduced.
- shock resistance in OFF position is a little lower
- mechanical lifetime is slightly reduced
- electrical lifetime is not or neglectible influenced
- risk of contact welding is increased by "slow" opening (under incidence of residual currents or under use of free wheeling diode) and by voltage drops.

Multimotor Applications
-
Many applications require more than one motor. In some instances, one drive
can supply two or more motors. When this happens, the current rating of the
mot...
