Installation Preparation

Before you get started make sure you have the following:

• CE Transducer CE42 Meter

• The power source of +12V DC to power the Galooli RTU (Elara)/CE Transducer CE42

• Power cables for the Elara/CE Transducer CE42 gateway - two cables with a thickness of 0.5mm. The length of the cables is determined by the distance between the power source of 220VAC to power the AC CE42 meter

• Electrical wires

• and the Elara/CE Transducer CE42 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 CE42 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, Multimetermultimeter, & 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

• Galooli Software Solution link

• Power Center installed - Click here to download.

• 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.

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 SW configurations, we can start with the actual phase line installment.

• The AC power meter is designed to operate on a 1 to a 3-phase system

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

• For single-phase installations, only one load cable passes through the AC meter to the load

1. Disconnect the phase wires from the circuit breakers.

2. Insert the phase power lines through the designated holes on the AC meter

a. IA = phase 1

b. IB = phase 2

c. IC = phase 3

Note - If the phase cables do not fit through the holes, refer to the CT rings sections at the bottom of this page.3.

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

3. For each phase line, append a wire and connect it to the designated voltage terminal on the AC meter

a. Phase 1 to terminal 1

b. Phase 2 to terminal 2

c. Phase 3 to terminal 3

5. Append the neutral wire to terminal 4 on the AC meter.

Please note the following:

1. Observe the polarity arrows that show the direction of the current flow on the side of the meter.

2. Reversed polarity will result in a disconnection of the meter.

3. AC Load lines pass through the CT rings provided to the load as shown below.  

1. Voltage lines are connected to the lower inputs 1, 2, 3, and 4 terminals.

CT Rings Installation

In a situation where the phase wires do not fit in the AC holes, we will need to use the CT rings to view the current information from the phases.

1. Unscrew the top of the CT ring with a small screwdriver.
   

2. Cable dimensions:

a. Minimum cable thickness 4[mm] or 0.04.”

b. Maximum cable length 30[cm] or 1.18.”
