Safety
If ASPMETER products are used in installations with circuits
higher than the product ratings, the circuits must be kept
segregated per UL 508A Sec. 17.5.
NOTE: 277/480 V AC wye-connected (center-grounded) power
systems operate within the 300 V AC line to neutral safety
rating of the ASPMETER series, and the operational voltage
limit (single-phase connection) as the line to neutral voltage
is 277 V AC in such power systems. Corner-grounded delta
480 V AC systems would not qualify, because the actual line
to earth voltage is 480 V AC on each leg, exceeding the
ASPMETER ratings.
NOTE: ASPMETER internal circuitry (cables and CTs) are not
circuits as defined by UL 508A, because they do not extend
beyond the ASPMETER itself without further safety/fire
isolation.
• UL listed under UL 508 as an “open-type device.”
• Maximum ambient air temperature for use is 60 °C.
• Installation category: CAT III
• The ASPMETER series must be installed in an appropriate
electrical and fire enclosure per local regulations.
For use in a pollution degree 2 or better environment only.
A pollution degree 2 environment must control conductive
pollution and the possibility of condensation or high humidity.
Consideration must be given to the enclosure, the correct use
of ventilation, thermal properties of the equipment and the
relationship with the environment.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the device may
be impaired.

ASPMETER solid core
Operations
The ASPMETER series branch current monitor is a device
designed to measure the current, voltage and energy
consumption of up to 46 circuits (42 branch circuits, one
3-phase main and one neutral).
The ASPMETER consists of a data acquisition board and two
21-unit current sensor strips, with four auxiliary inputs. The
strips are mounted on each side of the panelboard along the
termination points of each breaker. The conductor passes
through the appropriate current sensor before terminating
at the breaker. Each strip transmits the current data to the
data acquisition board.
Data is transmitted using an RS-485 Modbus protocol.
Each data acquisition board requires one Modbus address
for the set of two current sensors and four auxiliary inputs.
Data is updated roughly every two seconds. As a circuit
approaches the user-defined threshold, the ASPMETER
activates the alarm indicators.
The ASPMETERA measures both current and power for the
mains and branch circuits. The ASPMETERB measures both
current and power for the mains, and current only in each
circuit. The ASPMETERC measures current only for the mains
and branch circuits.

NOTE: Connect CT strips to the correct ribbon cable
connectors for each panel. The top connector is for
strip A, and the bottom connector is for strip B.
2. Auxiliary inputs: These 0.333 V AC inputs are used for
monitoring the main breaker or other high amperage source.

Wiring
Power must be disconnected and locked
out before making any wiring connections.
Connect 2-wire or 4-wire Modbus RS-485 daisy chain network
(Figures 1 and 2).
Figure 1.
Figure 2.
2-wire
4-wire
1. Mechanically secure the RS-485 cable where it enters
the electrical panel.
2. Connect all RS-485 devices in a daisy-chain fashion,
and properly terminate the chain (Figure 3).
Figure 3.
2-wire example
3. Shield the RS-485 cable using twisted-pair wire, such as
Belden 1120A. The cable must be voltage-rated for the
installation.
4. When tightening terminals, ensure that the correct torque
is applied: 0.5 to 0.6 N·m (0.37 to 0.44 ft·lb ) for connectors
on main board, 0.22 to 0.26 N·m (0.16 to 0.19 ft·lb) for
connectors on adapter boards (Figure 4).
Figure 4.
WARNING: After wiring the RS-485 cable, remove
all scraps of wire or foil shield from the electrical
panel. Wire scraps coming into contact with high
voltage conductors could be DANGEROUS!

Configuration
1. Communications configuration: Communications
parameters for the ASPMETER series are field-selectable
for your convenience. Please see the product diagrams
section (page 6) for selector location. The following
parameters are configurable:
• Baud rate: 9600, 19200 or 38400
• Parity: on or off
• Parity: odd or even
• Wiring: two or four
Example: 2-wire 19200 baud, no parity (default only)
2. Address configuration: Each Modbus device on a single
network must have a unique address. Set the switch block
to assign a unique address before the device is connected
to the Modbus RS-485 network. If an address that conflicts
with that of another device is selected, neither device will
be able to communicate.
3. Address the ASPMETER as any whole number between and
