Reactive Factor Controller CX plus
5
2 Installation and commissioning
1)
Before installation, the connection data of the CX plus must be compared with the data of the
supply network and of the installation.
2)
The working area must be disconnected from voltage and secured against unauthorised and
unintentional restart. The absence of voltage must be verified with a standardised instrument /
testing device. The voltage-free system must be grounded and short-circuited. Adjacent live
parts must be covered and / or placed behind barriers.
3)
The current transformer must be short-circuited. A current transformer that has NOT been
short-circuited generates very high voltages posing a danger to persons and equipment. The
current transformer can thereby be destroyed.
4)
Disconnect and remove the old reactive power controller.
5)
Plug the CX plus into the switch panel section and fix it with the two mounting brackets.
(Section 138 x 138 mm)
6)
Connect the protective conductor at the PE terminal of the metal back of the CX plus.
7)
Connect the connecting lines as per the wiring diagram (current transformer: K to power plant,
L to load).
8)
Remove the current transformer jumper.
9)
Switch on voltage.
10)
With a proper connection and correct connection data, the display lights and all symbols are
visualised on the LCD in the course of a display test for 1 second.
11)
The current transformer factor must be entered.
12)
If necessary, also enter the correct nominal voltage and the voltage transformer factor.
13)
Execute the “Automatic initialisation” (AI).
14)
If the “Automatic initialisation” was successfully finished, the message AUTO appears on the
display. Control starts after the discharge time lock (default: 75 s).
