1. INTRODUCTION
1.1 About User Manual
This User Manual is designed to help you for quick installation of RG-T. Before
installation and operation, please read this section very carefully.
1.2 Precautions for Safe Use and Installation
- Failure to follow those instructions will result in death or serious injury.
- Disconnect all power before working on equipment.
- When the device is connected to the network, do not remove the back panel.
- Do not try to clean the device with solvent or the like. Only clean the device
with dried cloth.
- Verify correct terminal connections when wiring.
- Electrical equipment should be serviced only by your component seller.
- Only for rack panel mounting.
- An F type fuse must be used and its current limit value must be 6A.
- No responsibility is assured by ENTES A.S or any of its subsidiaries
for any consequences arising out of the use of this material.
2. GENERAL
Power Factor Controllers are used for measurement and control of power
factor control units for central reactive power compensation. The Power Factor
measured by RG-T is compared with the set point values and in order to provide
necessary compensation, Power Factor Controller switches capacitor banks
ON and OFF automatically. RG-T is a microcontroller relay, designed for above
application in 144x144 case for flush mounting with rear plug-in connectors.
In addition to displaying the system's Cos
displays the RMS values of Voltage(V) and Current (I), Active Power (W), Reactive
Power (VAr) and Apparent Power (VA) of measuring phase.
