IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions that should be followed
during the installation and maintenance of this product.
To reduce the risk of electrical shock, and to ensure the safe installation and
operation of this product, the following safety symbols have been placed
throughout this manual to indicate dangerous conditions and important safety
instructions.
WARNING - A dangerous voltage or condition exists in this area.
Use extreme caution when performing these tasks.
AVERTISSEMENT - Une tension ou condition dangereuse existe dans
cette zone. Faire preuve dextrême prudence lors de la réalisation de
ces tâches.
CAUTION - This procedure is critical to the safe installation or
operation of the unit. Follow these instructions closely.
ATTENTION - Cette procédure est essentielle à linstallation ou
lutilisation de lunité en toute sécurité. Suivre ces instructions de
près.
NOTE - This statement is important. Follow instructions closely.
NOTE - Cette déclaration est importante. Suivre les instructions de
près.
All electrical work must be done in accordance with local, national,
and/or international electrical codes.
Before installing or using this device, read all instructions and cautionary
markings located in (or on) the VO-DPM, the manual, the batteries, the
inverter, etc.
Do not expose this unit to rain, snow or liquids of any type. This product is
designed only for indoor mounting.
To reduce the chance of short-circuits when installing or working with the
inverter or the batteries, use insulated tools.
Remove all jewelry such as rings, bracelets, necklaces, etc., while
installing this system. This will greatly reduce the chance of accidental
exposure to live circuits.
The inverter contains more than one live circuit (batteries and AC). Power
may be present at more than one source.
This product contains no user-serviceable parts. Do not attempt to repair
this unit.
ii
BATTERY SAFETY INFORMATION
Always wear eye protection, such as safety glasses, when working with
batteries.
Remove all loose jewelry before working with batteries.
Never work alone. Have someone assist you with the installation or be
close enough to come to your aid when working with batteries.
NEVER smoke in the vicinity of a battery or generator.
Always connect the batteries first, then connect the cables to the inverter
via a DC disconnect switched OFF. This will greatly reduce the chance of
spark in the vicinity of the batteries.
Use insulated tools when working with batteries.
When connecting batteries, always verify proper voltage and polarity.
Do not short-circuit battery cables. Fire or explosion can occur.
In the event of exposure to battery electrolyte, wash the area with soap
and water. If acid enters the eyes, flood them with running cold water for
at least 15 minutes and get immediate medical attention.

1.0 INTRODUCTION
The VO-DMP Features
The Vesta Online-Digital Power Monitor (VO-DPM) features six data
monitoring functions and two indicators including:
State of charge/amp-hour content (full or percent of capacity)
State of charge/voltage (real-time voltage level, historical high and low
system voltage)
Low Battery indicator
Full-charge indicator
Real-time power meter of load and charge
The unit is configurable for specific system or application functions such
as setting the CHARGED indication parameters, battery capacity, charging
efficiency, low-battery warning conditions. The VO-DPM can monitor any
battery supply from approximately 8 to 65volts, track energy consumption
and estimate remaining battery life.
In addition to its status monitoring features, the unit can act as a remote
control, switching the inverter OFF or ON (only on DR inverters).
The VO-DPM operates on 12-, 24-, or 48-volt battery systems.
NOTE: If the remote control feature is desired in the PDC, the RC8
remote in the Power Module must be disconnected. This feature is
only applicable of DR inverters.

2.0 CONFIGURATION
Setup
The VO-DPM is configured at the factory for monitoring a 24 VDC
system. These settings can be changed to meet specific system parameters.
The default settings are:
Charge Efficiency 94 %
%
Voltage (full-charge) 28.8 volts DC
V
KW
Amperage DC 35 amps
Amp Hours 400 Hours
LO
Low-Voltage Indicator 22.0 volts DC
Restoring the Factory Defaults
The factory defaults can be restored to their original settings if desired.
The default values will return to those listed above and are for a 24 VDC
system.
To restore the factory defaults:
1. Set the VO-DPM into the power saving mode by repeatedly pressing
the SELECT button until the LED display goes blank.
2. Press and hold the RESET button. The display will indicate ALL
flashing in the display. Continue to hold the RESET button until the LED
display remains blank.
The factory defaults are now restored.
Step 2 = ALL then blank

2.0 CONFIGURATION
Setting Parameters
Individual system parameters can be set by the following procedure:
1. Press the SELECT button until the mode selection indicator to be set is
illuminated.
2. Press the SELECT and RESET buttons simulataniously. Release both
buttons when the LED display flashes.
3. Press and release the RESET button to scroll through the selections (or
values) slowly, or hold the RESET button to scroll rapidly.
4. When the desired value is shown in the LED display, press the SELECT
button to accept it.

Charge Efficiency
Since batteries are not 100 percent efficient, more energy is required to
charge them than can be extracted. Some of this energy is lost in the form of
heat and gassing. An efficiency factor of 94 to 98% is typical for lead-acid
batteries. Consult the battery manufacturers specifications for other
batterytypes.
Set this value to 96% for new batteries and 94% (or lower) for batteries
already in service. The default setting is 94%. Changing this setting affects
the % State-of-Charge meter. The setting range is from 60 to 100%.
%
Setting the Charge Efficiency Factor
If the charge efficiency factor is not known and lead-acid batteries are
used in the system, set the charge efficiency factor to 94%. After the
batteries have been discharged and then fully recharged, the battery level
reading should be approximately full. If this reading is less than full when the
CHARGED LED ( ) flashes, increase the efficiency factor. If the battery
level is full before the CHARGED LED flashes, decrease the efficiency factor.
The setting is correct when the CHARGED LED flashes and the battery
level% is full.
1. Press the SELECT button until the BATTERY LEVEL LED (%) is
illuminated.
2. Press the SELECT and RESET buttons simulataniously until the LED
display flashes.
3. Press the RESET button to change the displayed efficiency factor.
4. Press the SELECT button to accept the value.
