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. 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 back of the
instrument to ensure that your instrument is equipped with the appropriate power supply
voltage, input voltages and currents.
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 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 power
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.

Electrical Connection
The remote display is connected to the meter via a 3-wire or
5-wire communication cable provided with two 15-pin D-type
connectors.
At distances of up to 100 m, the display receives power
through the communication cable directly from the meter.
Connect pins 1 and 8 on both sides as shown in Figure 2-13.
At distances above 100 m, supply power from a separate 12V
DC power source (a 12V AC/DC adapter can be used).
Connect the positive wire to pin 1 and the negative wire to pin
8 as shown in Figure 2-14.

Power Source Connection
Before connecting your meter to the power source, check the
label on the back of the device to ensure that it is equipped
with the appropriate power supply.
The power source can be dedicated-fused, or from a
monitored voltage if it is within the instrument power supply
range.
AC power supply: connect the line wire to terminal 12 and the
neutral wire to terminal 10.
DC power supply: connect the positive wire to terminal 12 and
the negative wire to terminal 10.
