STAR/DELTA VOLTAGE CONNECTION
Warning! Danger of death due to electric shock.
Before starting the assembly operations, exclude the voltage from the conductors and check that
they are equal to zero.
The commutability of the motor voltage makes it possible to use the gearmotor on both a 3 x 400 V
and 3 x 230 V power grid.
The motor is wired in the factory with star connection for a 3 x 400 V power grid.
For connection to a 230 V power grid, switch the motor onto a delta connection.
To commute the voltage onto the motor, wire the ends of the windings as illustrated in fig. 13-16.
When fixing the motor cables, pay attention that the cables are long enough to consent solid fixing,
to create a connection able to remain secure over time.
Pull the conductors to check if the connection is secure.
When switching over the motor for connection to a 3 x 230 V power grid, it is necessary to also adjust
the gearmotor.
3x 230V
3x 400V (default)
ANNUAL CHECK
BGR 232 directive “Windows, doors and main doors with mechanical
operation” is applied. It can be
obtained from the National Insurance Institute for Industrial Accidents of your trade association or
from us on request.
Maintenance interventions on windows, doors and main doors with mechanical operation must be
