6. ELECTRICAL CONNECTIONS

CAUTION: Observe safety regulations. Check whether the power supply (voltage, phase and
frequency) complies with the motor nameplate.

Terminal Access

• Take off the terminal compartment cover.
• Loosen cheese head screws inside the cover and remove multi- socket carrier.
• Attach conduit to terminal compartment cover.
CAUTION: Appropriate conduit and sealing methods must be followed to ensure the type of
enclosure furnished.

Wiring Connections

NOTE: The drawing contains the required information for correct actuator electrical connection.
Typical customer controls are also shown.
• Connect motor wires to the designated terminals. Connect ground to designated terminal.
• Connect control wires to designated terminals in accordance with drawing.
CAUTION: The following must be considered when wiring an AUMA actuator:
♦ The time delay (i.e., from limit or torque switch tripping until the motor is switched off) should not
exceed 20 ms. We strongly recommend switching off the motor directly by installing the
corresponding switches in the control wiring to the contactor. This concern is especially important
when using PLC's. Switch output to a PLC should be for indication only.
♦ Each switch has contacts which are not completely isolated and therefore are suitable only for the
same voltage potential. (See drawing for detailed information.)
♦ The valve manufacturer decides whether switching off in the end position should be by limit switch
(limit seating) or torque switch (torque seating).
