LIMITED WARRANTY
The manufacturer offers the customer a 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.
Only a duly authorized representative of the manufacturer may open your instrument. 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.
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.
WARNING
Read the instructions in this manual before performing installation and take note of the following precautions:
Ensure that all incoming AC power and other power sources are turned OFF before performing any work on the instrument. Protect the measurement AC Inputs voltage (V1, V2, V3) with 2A external overcurrent protection device and the power supply source inputs with 5A external overcurrent protection device, located close to the equipment.
Before connecting the instrument to the power source, check the labels on the back of the instrument to ensure that your instrument is equipped with the appropriate power supply voltage, input voltages and currents. Failure to do so may result in serious or even fatal injury and/or equipment damage.
Under no c ircu mstanc es should the instrum ent be connected to a power source if it is damaged.
To prevent potential fire or shock hazard, do not expose the instrument to rain or moisture.
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 secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.
Only qualified personnel familiar with the instrument and its associated electrical equipment must perform setup procedures.
Do not open the instrument under any circumstances when it is connected to a pow er source.
Do not use the instrument for primary protection functions where failure of the device can cause fire, injury or death. The instrument can only be used for secondary protection if needed.
Read this manual thoroughly before connecting the device to the current carrying circuits. During operation of the device, hazardous voltages are present on input terminals. Failure to observe precautions can result in serious or even fatal injury or damage to equipment.

To connect the internal CT to the high current external CT, pass the external CT wire through the meter CT core, see Figure 2-8a for details and observe the arrow that indicates the current direction.
In case of a retrofit application where each external CT ends with two wires:
1. Pass one wire through the meter CT core.
2. Connect the wire to one of the meter termination screws.
3. Connect the second wire from the external CT to the termination screw to close the loop.
