Nexus® 1450 Meter Quickstart Guide
IMPORTANT! Basic installation, wiring, and programming instructions are given in this Quickstart Guide. For
detailed information, see the Nexus® 1450 Meter User Manual and the CommunicatorPQATM, MeterManager-
PQATM, and EnergyPQA.comTM Software User Manual (both are available on the Nexus® Series CD which came
with your meter and on the electroind.com website - https://electroind.com/).
Mechanical Installation:
Mount the Nexus® 1450 Meter against any firm, flat surface. Use a #10 screw in each of the four slots on the
flange to ensure that the unit is installed securely. For safety reasons, mount the meter in an enclosed and pro-
tected environment, such as in a switchgear cabinet. Install a switch or circuit breaker nearby; label it clearly
as the meter’s disconnecting mechanism.
Installing an External Display:
The LED display P40N+ (shown above) and the LCD touchscreen display P70N mount using a standard ANSI
C39.1 drill plan.
• For the P40N+, secure the four mounting studs to the back of the panel with the supplied nuts.
• For the P70N, use the SMKP70N ANSI Mounting kit.

The recommended order of assembly for the ANSI Mounting kit is:
a. Attach the top bracket (5a) with its stud to the top back of the P70N display (1) - the bracket has two
hooks that fit into the slots on the top of the display.
b. Slide the top of the display with attached bracket under the front lip of the ANSI Mounting unit (2) and
tighten stud snugly - torque is to 3.1 in-lb.
c. Attach the bottom bracket (5b) with its stud to the bottom back of the P70N display - the bracket has
two hooks that fit into the slots on the bottom of the display; tighten stud snugly - torque is 3.1 in-lb.
d. Once the display is secured inside the ANSI Mounting unit, attach the studs and washers from the ANSI
Mounting kit (4) to the back of the unit.
e. Use the washers and nuts from the ANSI Mounting kit (6) to attach the ANSI Mounting unit with P70N
display to the panel (3) - torque is 3.5 in-lb.
Insert one end of the supplied RS485 cable into one of the meter’s RS485 ports set to Modbus RTU, Slave,
Address 1, and Baud Rate of 9600. Insert the other end of the cable into the back of the P40N+ or P70N
display (see below). See the meter’s user manual for detailed information and alternate P70N mounting.
Installing Input Output (I/O) Modules:
1. Secure the mounting brackets to the I/O module using the supplied screws
(#440 pan-head screws).
2. Secure the brackets to a flat surface using a #8 screw with a lock washer.
• Six feet of RS485 cable harness is supplied. Using the cable, connect the I/O
module’s male RS485 side port to the meter’s Port 4.
• If multiple I/O modules are connected together, secure a mounting bracket to
both ends of the group. (See figure below.) Connect multiple I/O modules by
connecting the male RS485 port on one module to the female RS485 port on
the next module.
See Chapter 10 of the meter’s User Manual for more information.
