MTR 52 420 2. Installation and dismantling of actuator 2.1 Installation Abide by safety measures! Before starting of mounting the EA onto the valve: • Check again whether the EA was not damaged during storing. • Check whether the adjusted operation angle and connecting dimensions of the actuator (see the nameplate) are in compliance with the valve parameters. - Page 17 MTR 52 420 a) Terminal board connection Connecting of the motor. Electric connection should be made through 2 cable glands M25 x 1,5. The recommended diameter of the connecting cable is 12,5 up to 19mm. Excitation winding, control winding and capacitor have to be connected in accordance with the recommended motor wiring diagram Z-296a.
