DANGER
General safety notes
Failure to observe the following instructions may result in serious injury or
death!
! DANGER
There is a risk of electric shock during installation!
Therefore, electrical devices may only be installed, operated, serviced and
maintained by qualified professionals. A professional is someone who has the
ability, experience and knowledge required for the construction, installation
and operation of electrical equipment and who has been instructed in
identification and avoidance of possible hazards.
During installation and maintenance, the relevant regulations for the
installation of switchgear and accident prevention must be observed and
adhered to. Devices with damaged or open housings or terminals must not be
operated on the power grid and must be
disconnected immediately.
After disconnecting the device, 10 minutes must be waited until the capacitors
have been discharged. Subsequently, doors or covers may be removed. It must be
checked whether the disconnected area is voltage-free using a standardized
measuring instrument.
Ther BELUK GmbH assumes no responsibility or warranty for damage to persons
and equipment caused by improper installation and use.

Connection diagram: CX plus -12R
NOTE: The CX plus is designed to control capacitive or inductive stages. Operating both stage types simultaneously is not possible.
Installation and commissioning
The working area must be de-energised and secured against unauthorised and
unintentional reconnection. The absence of voltage must be determined with a
standardised measuring device.
The de-energised system must be earthed and short-circuited. Neighbouring live
parts must be covered and/or cordoned off.
-
Before installation, the connection specifications of the CX plus must be compared with the data of the power grid.
-
The current transformer must be short-circuited.
NOTE: A current transformer which has been open-circuited generates a life-threatening voltage. This can lead to a destruction of the current transformer. -
Insert the CX plus into the panel cut-out and fix it by using both fixing clamps.
-
Connect the grounding cable to the intended terminal on the backside of the device.
-
All cables must be connected as it is depicted in the connection diagram.
-
Fuse protection of the unit with 6A
-
Remove the short-circuit bridge at the current transformer.
-
The voltage can now be switched on.
-
If the device is connected correctly, the display will light up for one second and all symbols will be displayed during a display test.

Un Nominal voltage
Ct Current transformer factor
External current transformer in the supply. Primary and secondary windings
result in the factor e.g., 150 | 750/5A.
Pt Voltage transformer factor
In the case that no voltage transformer is connected | 1
Ai Automatic initialization
The phase angle between voltage and current is determined and which stage
outputs are used.
YES: ALL stages are connected 3x
All connected stages “AUTO” unused outputs “OFF
