7 ELECTRICAL CONNECTION
The power supply voltage and frequency are indica-
ted on the identification tag and (or) on the electric
wiring diagram. Only the cover of the connection box/compart-
ment requires to be open for electrical connection. The other
covers should not be removed at the risk of introducing mois-
ture into the electronic controls.
A wiring diagram is normally supplied with the actuator.
If this is not the case, please ask our customer service.
Operating procedure :
a) Check the power supply characteristics with respect
to the rating nameplate.
In 3 phase, the phases order is not important as the INTEL-
LI+ system corrects the direction of rotation automatically.
b) Open the terminal box (fig. 2), connect the power and
control circuits (ring tongue not supplied). The screw
diameters is 3mm for the control and 4mm for the power
c) Check the wiring and the cover seal position.
d) Close the compartment and make sure that the cover
screws and cable glands are properly tighten.
Wiring specifications on SQ6 & SQ15
On SQ6 & SQ15 actuators, it's necessary to use shielded cables.
The cable gland must propose an earth connection and the
cable shield must be connected to the earth as follow :
a) Strip the cable
b) Insert the cable through cable gland
c) Fold the shield of the cable to bring it into contact with
the inside of cable gland.
A quick-fuse must be installed on primary phase of the actuator.
The fuse, not supplied by Bernard Controls, can be placed inside
or outside the junction box. Size of quick-fuse :
1 x 230VAC 50Hz: ......................................... 6,3 x 32mm 1A
1 x 115VAC 60Hz: ........................................... 6 ,3 x 32mm 1.8A
3 x 400/460VAC 50Hz: ........................... 6,3 x 32mm 0,5A
1 x 24VAC 50-60Hz: ................................... 6,3 x 32mm 10A
8 ACTUATOR ON VALVE SETTING INTRODUCTION
Each INTELLI+ actuator is set and checked at the factory.
If the actuator is delivered mounted on top of a valve, the open and closed positions as well as the
maximum torque values should have been adjusted by the valve supplier.
If an actuator on valve setting has to be performed or optimised, it can be done by simply connec-
ting the power supply. All settings and configurations can then be performed in a non-intrusive way
using the blue and red rotating knobs together with the graphical display.
The following chapters of this document include all the information necessary to perform actuator
on valve settings:

9 REMOTE CONTROL
The INTELLI+ actuator's remote control system can be operated using an external or an integral
voltage supply. The input circuits are fully opto-isolated. The self-hold pulse command system re-
quires four connecting wires on the client terminal strip: Common, stop, open and close. If the stop
push-button is not used, do not connect the STOP wire, open (or close) contact must be maintained
to operate the actuator.
9.1 DRY CONTACT CONTROL
In case of dry contact control, a jumper must be fitted across customer terminal 5-6.

9.2 VOLTAGE CONTROL
Remote control can use either in AC or DC voltage.
Use common terminal 5 for low voltages from 10 to 55V.
Use common terminal 4 for voltages from 55 to 250V.
Caution: never connect voltage sources above 55V
on common terminal 5.
