PM130 PLUS Powermeter Series_Installation Operation and Manual 3
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 at the back of the instrument
to ensure that your instrument is equipped with the appropriate power supply voltages, input voltages and
currents. Failure to do so may result in serious or even fatal injury and/or equipment damage.
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.
This equipment does not require cleaning for proper operation
