6. INSTALLATION GUIDELINE
6.1 Safety/Warning Precautions
Safety Precautions
Dangerous voltages capable of causing death are sometimes present in this instrument.
Before installation or beginning of any troubleshooting procedures the power to all
equipment must be switched off and isolated. Units suspected of being faulty must be
disconnected and removed first and brought to a properly equipped workshop for testing
and repair. Component replacement and interval adjustments must be made by a company
person only.
Warning Precautions
Read the instructions in this manual before performing installation and take note of the
following precautions:
All wiring must confirm to appropriate standards of good practice and local codes and
regulations. Wiring must be suitable for voltage, current, and temperature rating of the
system.
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 over current protection device and the power supply source inputs with
5A external over current protection device, located close to the equipment.
Before connecting the instrument to the power source, check the labels on 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 circumstances
don’t connect instrument 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.
Beware not to over-tighten the terminal screws.
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.
Upon receipt of the shipment remove the unit from the carton and inspect the unit for shipping
damage. If any damage due to transit, report and claim with the carrier. Write down the model
