LIMITED WARRANTY

The manufacturer offers the customer an 24-month functional warranty on the instrument for faulty

workmanship or parts from date of dispatch from the distributor. In all cases, this warranty is valid for 36

months from the date of production. This warranty is on a return to factory basis.

The manufacturer does not accept liability for any damage caused by instrument malfunction. The

manufacturer accepts no responsibility for the suitability of the instrument to the application for which it was

purchased.

Failure to install, set up or operate the instrument according to the instructions herein will void the warranty.

Your instrument may be opened only by a duly authorized representative of the manufacturer. The unit should

only be opened in a fully anti-static environment. Failure to do so may damage the electronic components and

will void the warranty.

NOTE

The greatest care has been taken to manufacture and calibrate your instrument. However, these instructions

do not cover all possible contingencies that may arise during installation, operation or maintenance, and all

details and variations of this equipment are not covered by these instructions.

For additional information regarding installation, operation or maintenance of this instrument, contact the

manufacturer or your local representative or distributor.

IMPORTANT

Please read the instructions in this manual before performing installation, and take note of the

following precautions:

1. Ensure that all incoming AC power and other power sources are turned OFF before performing any

work on the instrument. Failure to do so may result in serious or even fatal injury and/or equipment

damage.

2. Before connecting the instrument to the power source, check the labels on the side of the

instrument to ensure that your instrument is equipped with the appropriate power supply voltage, input

voltages, currents, analog output and communication protocol for your application.

3. Do not connect the instrument to a power source if it is damaged.

4. Do not expose the instrument to rain or moisture.

5. The secondary of an external current transformer must never be allowed to be open circuit when the

primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage,

fire and even serious or fatal injury. Ensure that the current transformer wiring is made through shorting

switches and is secured using an external strain relief to reduce mechanical strain on the screw

terminals, if necessary.

6. Setup procedures must be performed only by qualified personnel familiar with the instrument and

its associated electrical equipment.

7. DO NOT insert or remove I/O modules if the instrument is ON.

8. DO NOT open the instrument under any circumstances.

)Read this manual thoroughly before connecting the meter to the current carrying circuits. During

operation of the meter, hazardous voltages are present on input terminals. Failure to observe

precautions can result in serious or even fatal injury or damage to equipment.

Remote Displays

The SA300 can be ordered with an optional LED Remote Display Module (RDM) or LCD Remote Graphical

Module (RGM). Both have a fast RS-485 port and communicate with the SA300 through the Modbus RTU

protocol. Remote displays can be located at distances of up to 0.5 km from the device. The RGM can also be

ordered with an Ethernet 10Base-T port and can communicate with the SA300 through a local network.

The RDM has three six-digit windows with bright red LEDs well suited for dark areas. It allows the user to view

real-time RMS and harmonics measurements, status indication parameters, and perform basic setup

operations when installing and servicing the device.

The RGM is equipped with a color graphics LCD display and has extensive dialog capabilities, allowing the

user to view different fault and power quality information in a graphical form, such as waveforms, harmonic

spectrum, phasor and data trends, review latest fault and power quality reports for fast fault analysis, and

much more.

Upgradeable Firmware

The SA300 uses flash memory for storing device firmware that allows future upgrading of the device without

replacing any hardware component. The new features can be easily added to your device by simply replacing

the firmware through a local RS-232 port or Ethernet port.

2.2 Electrical Installation

2.2.1 Power Source Connection

The SA300 unit has two independent power supplies: main and backup. The standard power supplies may be

connected to an 85-265V AC or 88-290V DC power source. Lower voltage DC power supply options are also

available (see Appendix: Technical Specifications).

The main power supply connections are:

AC power: line to terminal J10 5; neutral to terminal J10 6.

DC power: positive to terminal J10 5; negative to terminal J10 6.

The backup power supply connections:

AC power: line to terminal J10 3; neutral to terminal J10 4.

DC power: positive to terminal J10 3; negative to terminal J10 4.

Copper wiring 1.5-2.5 mm2 (15 -13 AWG) should be used.

2.2.2 Current Inputs

SA310 and SA320 models have 4 current inputs up to 150A, connected to Relay Protection CT’s via J12

connector. Copper wiring 2.5 – 6 mm2 (10 AWG) should be used.

SA330 model has 4 additional current inputs up to 20A (ANSI) or 10A (IEC), connected to metering CTs via J14

connector. Copper wiring 1.5 – 3.5 mm2 (12 AWG) should be used.

2.2.3 Ground

Connect the chassis ground of the SA300 to the switchgear earth ground using dedicated wire greater than 2

mm2/14 AWG.

2.2.4 Voltage Inputs

SA300 models have 3 AC Y-connected voltage inputs of 690V (phase-to-phase) and neutral, and one separate

isolated AC voltage input of 400V.

2.2.5 Wiring Configurations

For models SA310, SA320, use any of the seven wiring configurations shown in Figures 2-3, 2-4, 2-5, 2-6, 2-7,

2-8 or 2-9; for model SA330, use any of the four wiring configurations shown in Figures 2-5a, 2-6a, 2-7a or 2-
