This assembly and operating manual describes the AB 450/ 650 with a 400V drive unit. For the
AB
450/ 650
, the following items are different:
•
The assembly height is limited to 55m (otherwise the voltage drop in the power line would be to o
heavy).
•

Requirements at place of installation
Electrical connection (on site)
•
A building site main switch cabinet with residual 400V 50Hz current circuit breaker and fusing
fort he feedpoint with 3 x 16 A slow-to-blow is required on the construction site. For the
AB
450 with 230Vdrive unit
you need a building site main switch cabinet with a 230V 50Hz
feedpoint with a minimum fusing of1 x 16 A slow-to-blow.
-
Connect the feeder for the control to the building site main switch cabinet (for the 400V –unit a er
CEE plug 5x16 A, 6h, red
with phase inverter
).
•
You need a rubber insulated flexible cable of at least
5 x 2,5 mm
2
or
3 x 4 mm

respectively (fort
he 230V drive unit (see accessories), in order to avoid voltage drop and thereby any loss
concerning the motor power.
