Section 3: Installation
Terminate the ground connections to the stud marked "ground".
One internal ground stud and one external ground stud are provided.
Before performing service or maintenance operations (unless otherwise indicated), ensure
that power is turned off to the unit to avoid injury or damage to equipment.
Check the wiring diagram (always included with the actuator) and the layout displayed on
the back of the terminal enclosure cover to ensure a correct electrical connection.
All terminations should be made with an insulated ring, or spade connectors using the
appropriate crimping tool. This operation will ensure an easily-made and correct electrical
connection.
Connect the motor supply cable previously sized in accordance with:
•
The absorbed current corresponding to the actuator nominal torque with the
torque-limiting device set at 100% (see the test certificate attached to
the actuator).
•
The applicable plant and safety norms.
Assemble the power terminal protective barrier located in the terminal board
compartment, using the enclosed screws. The control circuit (controls and signals) must
be connected by means of a multicore cable to the corresponding numbered terminals
according to the wiring diagram.
The internal cables of the actuator are also numbered according to the wiring diagram.
Actuators are always delivered with the motors wound and connected in accordance with
customer requests. Voltage and frequency values are stated on the motor nameplate.
