WARNING
Before installation ensure that all incoming power
sources are shut OFF. Failure to observe this
practice can result in serious or even fatal injury
and damage to equipment.
IMPORTANT
USE ONLY WITH SUPPLIED BFM CURRENT
TRANSFORMERS.
Connect the wires to the + and - inlets according to the
following polarity colors:
It is recommended to mark the cables and CTs with the
supplied tie markers.
CTs stickers I1 through I36 correspond to the Multi-Mon
current inputs with matching labels. Cable stickers 1 through
12 correspond to the Multi-Mon current terminal blocks with
matching labels.
Use the table from Appendix B to annotate your input
assignments and wiring connections.
LABELING EXAMPLE:
Assume you want to connect three HACSs to the device
terminal block 3 so these three HACSs would be connected to
the device inputs I7, I8, and I9 respectively:
1.
Take a CT connection cable, attach a tie wrap marker to
each side of the cable and mark them as 3 to indicate
that it should be connected to the device terminal block 3.
2. Put the CT label stickers I7, I8, and I9 directly on
HACSs to indicate that these HACSs will be associated
with the device current terminals I7, I8, and I9.
Safety Requirements
To ensure safety requirements the Multi-Mon must be
grounded - the protective ground terminal should be
connected to protective earth with a copper conductor or strap
with minimal length (less than 1 m desirable) and cross-
section 5.3 mm2(AWG10) at least.
The properly marked external 3-pole disconnect device with
circuit-breaker and a fuse 6 A, 600 V in every pole should be
installed between voltage measurement terminals and power
lines, located as close as possible (less than 2 m
recommended) to the Multi-Mon, as shown in figure 2-5.

mode is used for testing the device energy measurement
accuracy. In test mode, the energy and demand accumulators
do not account for consumed energy.
See Device Options in Section 3 and General Meter Setup in
Section 4 on how to put the device into energy test mode and
how to select the LED pulse rate and a submeter for testing.
FRONT PANEL DISPLAY
The Multi-Mon is provided with an LCD display and four push
buttons that are used for local meter reading and setup. See
Multi-Mon Display Operations in Section 3 for information on
using the front panel display.
Device Settings
Before operating your Multi-Mon, provide the device with
information about your particular environment. The device
front display (see Display Operations (Multi-Mon)) and the
supplementary Power Software (see Power Software
Application Software) allow you to configure the Multi-Mon for
your particular use.
PASSWORD
The Multi-Mon configuration setups are secured by a factory-
preset password. Contact your dealer for your primary
password. Later, you will be able to change the password via
the device Access Menu (see Meter Security).
SUBMETER SYSTEM
The Multi-Mon provides up to 36 submeters with separate
measurement and energy registers. Each submeter can
service current inputs dedicated to a particular consumer
(metering submeter) or be used as a totalization meter for
automatic totalization of energy from different sub-consumers
(totalization submeter). Additionally, the Multi-Mon provides
four more totalization submeters (37 through 40) that you can
use for totalization purposes when all 36 metering submeters
have been utilized.
A submeter remains inactive while there are no current inputs
associated with the submeter (see Channel Assignments), or
until you link another submeter as a source to its energy
registers making it a totalization submeter (see Setting up
Total and Tariff Registers). The Channel Assignment setup
allows you to link one to three current inputs to each submeter
and to specify the primary rating of the current transformers. A
totalization submeter provides totalization of energy from any
number of metering and totalization submeters.
By default, your device is configured for 12 three-phase
metering submeters with 100 A (maximum) current inputs
(50 A nominal rating).
SUBMETER ADDRESSING
The Multi-Mon uses the Modbus communication protocol for
data transmission and accessing setups through
communications. A full description of the communications
protocol is found in the Multi-Mon Modbus Reference Guide
provided with your device.
Each active submeter in the Multi-Mon is assigned a unique
communication address that allows accessing its private
registers and setups. All submeter addresses are assigned
automatically in a sequential order starting with the device
base address that is programmed through the device
Communication Setup (see Setting Up Communication Ports).
The following table illustrates submeter addressing in the
device with the base address N.
Your device is factory preset to address 1 and occupies the
range of addresses 1 through 12, configured for 12 three-
phase submeters.
NOTES:
1. Device setup settings, excluding the alarm set-
points and data log setup,are shared across all
submeters. Though you can read or write them
using any submeter address, your changes affect
all submeters in the device.
2. When using the ExpertPower client, submeter
address 99 on the Ethernet port COM2 is
reserved for the Multi-Mon router and must not fall
inside the range of the submeter addresses for
this port.
Select your submeters (both metering and totalization) in a
sequence without gaps so that your device does not occupy
unnecessary network addresses.
If you connect a number of devices to a serial network,
allocate a range of addresses for each device so that they do
not overlap. For example, if you use three devices with 12
submeters in each one, assign the base address 1 to the first
device, the address 13 to the second, and the address 25 to
the third device so that they will occupy three non-overlapped
address ranges 1 through 12, 13 through 24, and 25 through
36.
BASIC DEVICE SETTINGS
For proper device operation, select the correct power
frequency (see Basic Device Settings) and set the correct
primary ratings for device current inputs (see Channel
Assignments) before you connect the device to your network.
ENERGY/TOU SYSTEM
The Multi-Mon provides 4 separate billing energy (total/
summary and parallel tariff and maximum demand) registers
for each individual submeter. Each register can be linked to
any internal energy source or another submeter. The first
billing register in your meter is linked to the kWh accumulator
by default. Other registers are not operational unless you
configure them through the Energy/TOU Setup (see
Configuring Billing Energy and TOU Registers).
Device Diagnostics
Device diagnostic messages may appear as a result of the
Multi-Mon built-in diagnostic tests performed during start-up
and device operation. See Device Diagnostic Codes in
Appendix F for the list of diagnostic codes and their meanings.

The device diagnostics status is stored in a non-volatile
register, which may be inspected and cleared via Power
Software, from the meter display or from a user application. All
diagnostic events with time stamps are also recorded in the
device Event log and can be inspected via Power Software
(see Retrieving the Event Log in Section 4).
See Diagnostics Display and Reset in Section 3 on how to
inspect and clear the device diagnostics status from the
display. See Viewing and Clearing Device Diagnostics in
Section 4 on how to inspect and clear the device diagnostics
status via Power Software. Refer to the Multi-Mon Modbus
Reference Guide for the diagnostic register address and
layout.
In the event of a device fault, check the fault reason and clear
the device diagnostics. In the event of a time fault, update the
device clock. In the event of a configuration reset, check the
setup affected by the fault via the device Event log, and then
verify the setup data.
Hardware failures are normally non-critical recoverable faults
that do not cause a system failure but may cause data loss.
Hardware failures are often caused by excessive electrical
noise in the region of the device.
If the device continuously resets itself, contact your local
distributor.
SECTION 3:
MULTI-MON DISPLAY OPERATIONS
Startup Diagnostics
