4.- DESCRIPTION OF THE UNIT
The figure shows the description and location of the analyzer's components.
Connector B is used to connect the voltage references of the unit. Connector B is used to
connect the voltage references of each phase (marked with VL1, VL2 and VL3), the
neutral reference (marked with N) and two additional pins (5 and 6) used to power the
unit, as shown in the figure. Terminals 5 and 6 are used to power the unit independently
from the measurement, in order to guarantee a permanent recording flow when powering
the analyzer with an uninterruptible power supply system. More information about the
unit's measurement and power supply features in section 4.1 Electrical Features.
SD card slot is used to insert the removable SD memory card to record the electrical
parameters measured by the unit. Read chapter 6.2 Insert SD card to see the position of
the SD card.
