Precautions for Safe Use and Installation
Consult the operating instructions before using the equipment. Following these precautions is a must for an error-
free operation and maintaining the eligibility for a warranty.
Therefore, please read this manual carefully before commissioning and using the RG3-12C/CS.

ATTENTION!
No responsibility is assured by the manufacturer or any of its subsidiaries for any consequences rising out of
disregarding these precautions while handling the RG3-12C/CS.
Important Note for System Connection.
First, connection type of auxiliary supply, voltage measurement and current measurement input must be 3 phase-
neutral. The device will not operate properly if these connections are not done.
A 3-phase capacitor must always be connected to the first step. Providing that this connection is followed for the
first capacitor step, 3-phase or single phase capacitor banks can be connected to the other steps in any order
according to your systems needs.

2)
Do not energise the device before verifying terminal connections.

Maintenance, installation and operation of RG3-12C/CS must be performed only by the qualified electricians.
Do not operate the device in undervoltage conditions.
Do not open the RG3-12C/CSs housing. There are no user servicable parts inside it.
RG3-12C/CS is connected to the network by means of a current transformer. Do not disconnect the current transformer
terminals. If you disconnect them, be sure to short-circuit the terminals or connect them to another parallel load which
has a low impedance. Otherwise, dangerously high voltage at the secondary side of current transformer may cause
an electric shock.
Do not use this product for any other purpose than its original task.
When device is connected to the network, do not remove the front panel.
Do not clean the device with solvent or similar items. Only clean with a dried cloth.
Verify terminal connections before commissioning.
Electrical equipment should be serviced only by your competent seller.
Device is only suitable for panel mounting.
Generator Input Connection
The connection to the generator input of the device must be done in a way that the energy comes to the system after the
generator connection to the network has been established. Otherwise, the device will switch to generator mode when the
generator is started for maintanence purposes.
If there is a voltage between 110-250 VAC present on the generator inputs of the device, the target set on the deviceCos j
is deactivated and target is activated. Then the device starts the compensation according to target Cos 2. This Cos 2j j
operation mode continues until the voltage on the generator input is disappeared.
Monitoring the measured temperature
In order make a correct measurement, J type (Fe/Cu-Ni) thermocouple must be connected to TEMP terminal and keep
worked at least 30 min. In order to observing the measured environmental temperature, press UP/DOWN buttons untill the
displaying the xxx.x  value.
NOTE: RG3-12C/CS temperature measurement feature is optional.
1.2 Front Panel
On the front panel; 3 display lines with four digits which consist of 7
segments, 4 buttons, alarm, capacitor step and display LEDs exist.
Measured parameters are observed in the related displays. Displayed
values for related parameters are selected via indicator leds. When an
alarm occurs, related alarm LED blinks. 12 capacitor step LEDs indicate
which capacitor step is switched on. Detailled information about buttons,
display, alarm and capacitor step LEDs will be explained in the coming
sections.

UP
DOWN :
In the observation mode, they are used for
switching between observed parameters. In
the programming mode, they are used for
browsing the menu choices and changing
the parameter values.
In the observation mode, it is used to switch
between harmonic measurement mode and
instant value measurement mode. In the
programming mode, it is used to return to
the previous menu or exit without saving any
committed changes.
In the observation mode, it is used to show
the harmonic value of the measured
parameter. If it is pressed for 3 seconds,
programming mode appears. In the
programming mode, it is used to enter to a
menu or confirm the data entry.
1. INTRODUCTION
1. Gene l Information1 ra
In todays world, the reactive loads on a network continue to increase with
the contracted power rise. The increase of the power on transformers,
transmission lines and generators caused a rise in the reactive power levels
just as much and maybe more than the active power levels. To prevent any
overloads and under voltage conditions, the compensation of the reactive
loads became a necessity in todays energy network.
Power factor controllers monitor the reactive power of a plant and try to
match the power factor value which is defined as the ratio of the active
power(W) to the apparent power(VA) to a power factor valuewhich is defined
on the device by the user.
RG3-12C/CS power factor controller is designed for reactive power
compensation in single phase and 3-phase systems.
RG3-12C/CS compensates each phase separately and so, this makes
RG3-12C/CS series a unique solution for unbalanced load compensation.
In order to achieve this feat, single phase and 3-phase capacitor steps
must be connected to the device at the same time.

1) Panel cut-out dimension must be 139 mm x 139 mm
(Type PR16).
2) Before installation, remove the mounting brackets.
3) Mount the device to the front panel.
4) Insert the mounting brackets.
5) Voltage and current terminals are designed for cables
with a cross-section of 2,5 mm2 but these terminals are
suitable for cables with cross-sections up to 4 mm 2.
6) CAT5 cable is recommended for RS-485 input terminal.
Excessive force can damage the device.
Turn the screw into the terminals and tighten until the
RG3-12C/CS is secured in place.
