3.1.3 Electric connection and checking of function
Follow up with connecting the EA with mains or master system.
1. Follow instructions in the part "Requirements for specialized...."!

. While laying electrical line abide by the instructions for heavy current installations. Power supply
cables must be of the type approved. Minimum thermal resistance of power supply cables and wires
must be +90°C.
3. Cables to terminal boards or connectors lead through cable glands.
4. Before initiation ES into operation internal and external protection terminals are needed to be
connected.
5. While fixing the cable it is needed to count with allowed bend radius to avoid damaging or deformation of the
sealing element of the cable gland. The leads are to be fixed with the solid construction at most 150 mm from the
cable glands.
6. Wires of input control signals to controller and output signals it is necessary to lead them separately with thrust
wires or it is necessary to use shielded wires.
7. Reversation of the EA is sure, if the period between switching-off and switching-on of power supply for the
reversed movement of the output part is minimally 50 ms.
8. The EA are delivered with cable glands, which in case of tight putting on the leads assure protection enclosure
up to IP 68.
9. The face areas of the control part cover have to be before re-mounting clean, coated with grease without any
acid (e.g. vaseline) and sealing not damaged to avoid joint corrosion.
Connecting with the master system:
EA can be controlled by: - by analogue signals through the built-in controller
- by binary inputs 24 V DC
EA is connected according to wiring diagram under the cover of EA.
In version ULR PA it is necessary to do autocalibration in operation according by enclosure
assure the optimal function .
Abide by instructions of valve producers, whether switching-off end positions is to be realised with
position or thrust!
NOTE:
1. To connect the input control signals and output signals is needed to use shielded wires with steel wire
braid (Galvanised Steel Wire Braid GSWB
Ξ
), for example cable type "Bruflex ® HSLCH", 4x0, 5
(company Bruns Kabel).
2. Electrical installation of the actuator and its connection to switching, protection and safety devices can be
performed by a person with competent qualification only. All the respective standards and electric wiring
diagrams cited in the Manual must be kept.
3. The control of all the terminals must be realized after electrical connection of inlet cables. Junction
terminals must not be stressed by the connected cables neither by traction nor by bending. Performance
of the following measure is recommended in case alluminium wires are used:
Immediately before the installation of the aluminium wire the oxidized layer on the wire must be removed
and to prevent a new oxidation of the junction a neutral vaseline stall be aplied.
