Preparation

Installation Preparation

Before you get started make sure you have the following:

• CE Transducer CE42CT Meter

• The power source of +12V DC to power the Galooli RTU and CE Transducer CE42CT

• Power cables for the Elara/CE Transducer CE42CT gateway - two cables with a thickness of 0.5mm. The length of the cables is determined by the distance between the power source and the Elara/CE Transducer CE42CT Meter gateway

• RS485 To USB Converter & two 0.5mm thick communication cables. The length of the cables is determined by the distance between the RS485 to the USB converter and the computer

• Screwdriver (Slotted & Phillips)

• Communication cables for the CE Transducer CE42CT inputs and outputs. Cables with a thickness of 0.5mm. The length of the cables is determined by the distance between the sensors and the surrounding environment

• Electronic tools – screwdriver, multimeter, & f-crimp tool

 Additional information:

• The device is designed to be installed on a din rail

• Make sure that you have sufficient space for its mounting

• We recommend mounting the AC meter next to phase breakers - this act can simplify the process of disconnecting the cables from the breakers, passing the load cables through the meter, and then connecting them back to the breakers

Configuration Preparation

• PC or laptop computer

• Power Center installed - Click here to download.

• Galooli Solution Link - Click here to login.

• RS485 to USB converter - Refer here for driver installation instructions.

• Technical Booklet - Provided by Galooli Support team.

Note! Make sure your computer recognizes the COM port at the “Device Manager”. Otherwise, install the proper driver.

ID Configuration

After everything is connected, we can start the process of changing the ID of the AC meter, according to the wiring diagram.

1. Open PowerCenter.

2. Open the “Active Device” drop-down menu, and select the “Power Device”.

Phase Lines Installation

Safety: 

• Before installing the load cables and connecting the voltage lines, it is necessary to cut off the AC power. Once the wiring procedure is completed, you may turn the AC power back on

• Any electrical installment should be carried out only by a certified high-voltage electrician

After setting up all the configurations, we can start with the actual phase line installment.

• The AC power meter is designed to operate on a 3-phase system, but we will demonstrate how it can also be used with a 2-phase system in this document.

• For three-phase installations, all three load cables should pass through the AC meter to the load

3-Phase Installation

1. Disconnect the phase wires from the circuit breakers.

2. Connect each phase line to the designated voltage terminal on the AC meter

3. Reconnect the phase power lines to the original circuit breaker location.

Image Added

2-Phase Installation

1. Disconnect the phase wires from the circuit breakers.

2. Connect each phase line to the designated voltage terminal on the AC meter
   

3. Reconnect the phase power lines to the original circuit breaker location.

 CT Rings Installation

CE Transducer CE42 Ac meter works only with a CT ring. We found that the most suitable current rings are https://galooli.atlassian.net/wiki/spaces/KP/pages/2441969800/AC+Current+Transformer+Rings+CT#CE-CTH-Split-Core%5BhardBreak%5D

3-Phase Installation

1. Connect the cables from the CT ring to the AC meter according to the relevant phase.

2-Phase Installation

2. The AC power cable should be threaded through the ring as shown in the picture below. Ensure that the cable is threaded correctly by remembering that it enters from the opposite side to the phase cables.
