Mechanical connection for versions with flange TGL (Fig. 5)
Connection procedure:
•
Check the labels, whether the travel of electric actuator
and travel of armature are corresponding.
•
Set the armature (B) into position „closed“ and set electric
actuator (A) into half-position.
•
Put electric actuator (A) on the armature (B).
•
Unscrew the clutch bolts (3) and disassembly parts of the
clutch.
•
Screw the nut of clutch (3) on output shaft of armature (10)
in a way, that the flange of electric actuator (5) will fit to the
flange of armature (13).
•
Connect the flanges by tightening of central nut (11).
•
Check connecting dimension "L" between the clutch and the
flange (13) in the position of contact with pillars according to
dimensional drawing and a type number on the plate of
electric actuator.
•
Release the clutch nut (3) by one turn counter clockwise and
secure it by nut (12), thereby reaching pre-stress securing
proper seating of armature.
•
By hand wheel (2) approach output shaft of electric actuator
to the shaft of armature (10) and fasten parts of the clutch by
bolts.

2.1.2 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 professional qualification"!
2. 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 +80°C.
3. Cables to terminal boards or connectors lead through cable glands.
4. Before putting EA into operation it is necessary to connect inside and outside grounding
terminal.
5. Wires of input control signals to controller and output signals from current converter it is necessary to
lead them separately with thrust wires or it is necessary to use shielded wires.
6. To prevent moisture from entering the actuator around the connecting cables, the cables must be sealed with
silicone material at the point of penetration through device shell.
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.
