4.3.3 Connections and electrical diagrams
•
“DGT” drive units are equipped with self/braking electric motors, designed to be electrically
powered by a three-phase alternating current, at the voltage specifications indicated on the
motor’s nameplate.
•
The electrical connection diagram is indicated on the nameplate inside the terminal cover on
each motor.
Set the electrical connections on the motors as follows:
1. Check to make certain the voltage indicated on the nameplates on the motors for the sliding units corresponds
to the power voltage available.
2. Verify the suitability and correct operation of the electrical system and
grounding
.
3. Perform the electrical connections on the motor terminals, in relation to their type, as indicated in the electrical
diagram (fig. 15), i.e. connect the suitably sectioned four-pole cable to the respective terminals, connecting the
yellow/green conductor to the ground terminal and tightening the terminals to avoid bad contacts.
