Safety
FCC Compliance
This device has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at user’s own expense.

The following section illustrates the 12 channel model. The mounting components are slightly
different, but follow the same procedure.
STEP 1) Remove top cover screws (4x) and high voltage cover screws (2x) –provided
STEP 2) Locate, mark, and drill wall mounting points (2x–6x—customer supplied)
The plastic enclosure itself can be used as a template for marking the drill locations on the
wall.
If the meter is not available for use as a drill template, a drawing indicating the spacing between
mounting holes can be found in the appendix. The centerline holes are intended for fastening
to wall studs. If hollow wall fasteners are used, the outer 4 mounting points are recommended.

Connecting Voltage
Connect the voltage leads (L1, L2, L3, and N, as necessary) to the meter through a dedicated
disconnect or circuit breaker. A voltage lead of 14 AWG THHN Minimum 600VAC rating (or
equivalent) is required.
IMPORTANT: Verify the circuit breaker is marked as the disconnect
breaker for the meter.

Wiring the AcquiSuite™ Ally Meter in a 4-wire, 3 ɸService Panel
Illustrating the intended wiring configuration for each of the Service Types
available in the Service drop-down list under “Meter Setup”
Note: The AcquiSuite™Ally Meter Series uses the “Neutral” Terminal as a
voltage reference. For systems without a neutral conductor, Leviton
suggests connecting a ground wire to this terminal. If the neutral terminal
is left open, L-L measurements will be accurate, but L-N measurements
may not be symmetric. If a ground wire is connected to the Neutral
terminal, <2mA will flow into the ground wire.

Wiring the CTs to the AcquiSuite™ Ally Meter
The image below is the counterpart to the service panel illustration and indicates how to
connect CTs to the input terminals on the AcquiSuite™ Ally, for each service type. For service
types that are not specifically listed, it is recommended to choose “single phase” service and
configure each channel individually. Three phase loads are illustrated on the left and split phase
loads on the right as an example only. Elements are fully interchangeable on the meter.
•Current and voltage inputs must be installed ‘in phase’ for accurate readings (e.g. CT1
on Line 1, CT2 on Line 2) Orientation is critical: Ensure that all CTs are properly oriented
with the line and load, as marked. Failure to install CTs in the correct orientation and on
the correct phase will lead to inaccurate meter readings.

Communication Verification
Verification includes confirmation of BOTH the physical interface settings
(Serial or Ethernet) and the protocol (Modbus or BACnet) settings.
The LCD User interface can be used to quickly confirm the settings required for each
combination of interface and protocol. The interface is intuitive and groups together commonly
associated registers. The complete interface is presented in Appendix A as a navigational map.
Arrows indicate how to move from one menu display to the next. A Reverse Contrast entry in
the documentation indicates the active menu item in a list which corresponds to a blinking
character in the physical LCD. The ENTER button is used to select a property and up / down
buttons are used to select among the values supported by the meter. Note that changes to the
meter configuration are limited to the communication interface using the LCD. If additional
changes (such as CT type) are required they must be made using a software interface.

If your AcquiSuite™ Ally model does not include the LCD user interface or if you prefer to verify
the installation using software, then verification is facilitated through the AcquiSuite™ Ally

the section on Configuration Details in the full user manual, or the AcquiSuite™ Ally Web App.
Pulse Inputs
Ally ACM12 meters are equipped with 4 pulse inputs and Ally ACM48 meters (hardware version
I) are equipped with 2 pulse inputs. Pulse counting supports accumulation of consumption data
from any external meter using a dry contact (Form A Relay) or open collector outputs. The
AcquiSuite Ally pulse inputs are compatible with “low speed” meters. The pulse duration must
exceed 50mS in both the logic low and high state allowing for a maximum input frequency of 10
Hz.
Pulse scaling, resetting and accumulated values are accessed through registers and are “system”
in scope. Refer to the register list, Obvius Ally Configuration Console, or videos for more
information.
