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 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. Failure to

do so may result in serious or even fatal injury and/or equipment

damage.

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 and

communication protocol for your application.

Under no circumstances should the instrument 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 made

through shorting switches and is secured using an external strain relief to

reduce mechanical strain on the screw terminals, if necessary.

Setup procedures must be performed only by qualified personnel

familiar with the instrument and its associated electrical equipment.

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.
