Application • For valve attachments according to EN ISO 5211
• For rotating, non-rising valve stem
5.3.1.1 Actuator (with coupling): mount
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the actuator to the valve (e.g. with bore and keyway, two-flat or
square bore).
Assemble valve and actuator in the same end position. As standard, the actu-
ator is supplied in end position CLOSED.
a) Recommended mounting position for butterfly valves: End position CLOSED.
b) Recommended mounting position for ball valves: End position OPEN.
We recommend applying liquid thread sealing material to the screws to avoid
contact corrosion.
Assembly steps 1. If required, move actuator in same end position as valve using the handwheel.
2. Clean mounting faces, thoroughly degrease uncoated mounting surfaces.
3. Apply a small quantity of grease to the valve shaft [2].
4. Place coupling [1] onto valve shaft [2] and secure against axial slipping by using a
grub screw [3] or a clamping washer and a screw with curved spring lock washer
[4]. Observe dimensions X, Y or L. Refer to following picture and table Mounting

6.1 Basic information
WARNING Electric shock due to presence of hazardous voltage!
Failure to observe this warning could result in death, serious injury, or property dam-
age.
àThe electrical connection must be carried out exclusively by suitably qualified per-
sonnel.
àPrior to connection, heed basic information contained in this chapter.
Wiring diagram/terminal
plan
The pertaining wiring diagram/terminal plan (in German or English) is attached to the
device in a weather-proof bag, together with these operation instructions. It can also
be requested from AUMA when indicating the order number (refer to name plate) or
downloaded directly from our Website (http://www.auma.com).
NOTICE Valve damage when connecting to actuator controls!
àNORM actuators require actuator controls: Connect motor via actuator controls
only (reversing contactor circuit).
àRespect the type of seating specified by the valve manufacturer.
àThe torque switches also serve the purpose of valve overload protection and must,
therefore, also be connected for limit seating.
àHeed wiring diagram.
Delay time The delay time is the time from the tripping of the limit or torque switches to the motor
power being switched off. To protect the valve and the actuator, we recommend a
delay time < 50 ms. Longer delay times are possible provided operating time, output
drive type, valve type, and type of installation are considered. We recommend switch-
ing off the corresponding contactor directly by limit or torque switch.
Limit and torque switches Limit and torque switches can be provided as single, tandem, or triple switches. Only
the same potential can be switched on the two circuits (NC/NO contact) of each single
switch. If different potentials are to be switched simultaneously, tandem switches or
triple switches are required. When using tandem/triple switches:
• For signalling use the leading contacts DSR1/TSC1, DOEL1/TSO1, WSR1/LSC1,
WOEL1/LSO1.
• For switching off use the lagging contacts DSR/TSC, DOEL/TSO, WSR/LSC,
WOEL/LSO.
Current type, mains
voltage, mains frequency
Type of current, mains voltage and mains frequency must match the data on the motor
name plate. Refer to Motor name plate [}9].
Figure12: Motor name plate (example)

[3] Mains frequency
Protection and sizing on
site
For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches or circuit breakers have to be provided by the customer.

Electrical connection
18
The current value for sizing the protection is derived from the current consumption of
the motor (refer to Motor name plate [}9]).
We recommend adapting the switchgear sizing to the max. current (Imax) and selecting
and setting the overcurrent protection device in compliance with the indications in the
electrical data sheet.
Safety standards Safety measures and safety equipment must comply with the respectively valid na-
tional on site specifications. All externally connected devices shall comply with the rel-
evant safety standards applicable for the place of installation.
Connecting cables, cable
glands, reducers, blanking
plugs
• We recommend using connecting cables and connecting terminals according to
nominal current (IN). (Refer to Motor name plate [}9] or electrical data sheet.)
• For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
• To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
• Use connecting cable with appropriate minimum rated temperature.
• For connecting cables exposed to UV radiation (outdoor installation), use UV res-
istant cables.
• For connecting position transmitters, only use screened cables.
