CCS WattNode Pulse WNB-3D-240-P, Reference Manual

Page: 6 / 38

6 Overview
M, N, O: Current transformer (CT) inputs. These indicate CT screw terminals. Note the white
and black circles at the left edge of the label: these indicate the color of the CT wire that should
be inserted into the corresponding screw terminal. The terminals marked with black circles are
connected together internally.
P: Pulse output common (COM). This is the common terminal for all three pulse output chan-
nels. This terminal should be more negative than the
P1
,
P2
, and
P3
terminals (unless the
meter was ordered with Option SSR ).
Q, R, S: Pulse outputs (P1, P2, P3). These are the pulse output channels. Different models use
one, two, or three channels. They should always be positive relative to the common terminal.
T: Serial number. This shows the meter serial number and options if any are selected. The
barcode contains the serial number in Code 128C format.
U: Mains supply rated voltage. This is the rated supply voltage for this model. The
V ~
indicates
AC voltage. For wye models, this voltage should appear between the
N
and
Ø A
terminals. For
delta models, this voltage should appear between the
Ø A
and
Ø B
terminals.
V: Mains frequencies. This indicates the rated mains frequencies for the meter.
W: Maximum rated power. This is the maximum power consumption (watts) for this model.
X: Manufacture date. This is the date of manufacture for the WattNode meter.
Y: Caution, risk of electrical shock. This symbol indicates that there is a risk of electric shock
when installing and operating the meter if the installation instructions are not followed correctly.
Z: Attention - consult Manual. This symbol indicates that there can be danger when installing
and operating the meter if the installation instructions are not followed correctly.
