7. Electrical connection
Work on the electrical system or equipment must only be
carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of
such an electrician and in accordance with the applicable
electrical engineering rules.
7.1 Connection with AUMA plug/socket connector
.
Check whether type of current, supply voltage, and frequency comply with
motor data (refer to name plate at motor).
.
Loosen bolts (50.01) (figure 3) and remove plug cover.
.
Loosen screws (51.01) and remove socket carrier (51.0) from plug cover
(50.0).
.
Insert cable glands or conduit fittings suitable for connecting cables
(The enclosure protection stated on the name plate is only ensured if
properly sealed connections are made).
.
Seal cable entries which are not used with sealed threaded plugs.
.
Connect cables according to order-related terminal plan.
.
The terminal plan applicable to the actuator is placed inside the terminal
compartment, the operation instructions are attached to the handwheel in
a weather-proof bag.
A special parking frame (figure C-2) for protection against touching the
uncoated contacts and against environmental influences is available.
7.2 Delay time The delay time is the time from the tripping of the limit or torque switches to
the motor power being removed. To protect the valve and the actuator, we
recommend a delay time < 50 ms. Longer delay times are possible provided
the operating time, output drive type, valve type, and the type of installation
are considered.
We recommend to switch off the corresponding contactor directly by the limit
or torque switch.
7.3 Reversal time Actuators operated via non AUMA supplied controls must include a
minimum reversal time delay of 100ms.
