Introduction
The IPSi505MW series of Intelligent Pure Sinewave Inverters are designed specically for
powering computers and other sensitive AC loads in mobile, off-grid environments. They
produce pure sinewave AC power, identical to a conventional AC outlet.
Built for service in rugged, high moisture environments this unit features upgrades including
expanded operating temperature, MIL-spec connectors, water-tight seals and enhanced shock
and vibration protection.
Internally, the IPSi505MW is controlled by a sophisticated Digital Signal Processor (DSP) for
optimal control and the most efcient operation possible. The heavy-duty Toroidal Power
Transformer steps the low voltage AC produced by the Power MOSFET Transistors to 220
VAC at 50 Hz. Additional ltering on the AC output reduces or eliminates EMI noise that can
interfere with sensitive communications equipment.
Built for the safest operation possible, this unit features low voltage warning with shutdown
circuitry to protect the DC power source. While the inverter is safeguarded by high voltage
and over temperature protection both with shutdown circuitry. All the alarm conditions can
be monitored on the bright LED indicator display which can also be mirrored on the optional
remote control panel.
Using the free-to-download InverterWizard software from Analytic Systems, you can change
the output frequency, adjust the voltage shutdown thresholds and view and record operating
data from any PC with a standard USB interface.
The box you have received should contain the following:
• 1 IPSi505MW Intelligent Pure Sine Inverter
• 1 compatible USB cable
• 1 Warranty Card

• Blinks red when the input voltage nears the minimum limit for proper operation.
• Glows red when the input voltage is too low for proper operation. The Bypass
LED will also glow red and the Invert LED will turn off.
HIGH
VOLTAGE
• Blinks red when the input voltage nears the maximum limit for proper operation.
• Glows red when the input voltage is too high for proper operation. The Bypass
LED will also glow red and the Invert LED will turn off.
OVER TEMP • Blinks red when the unit’s internal temperature nears the safe limit. The
inverter will automatically derate its maximum power rating to try to
maintain a safe operating temperature.
• Glows red when the inverter is too hot to operate. The Bypass LED will
also glow red and the Invert LED will turn off.
OVER LOAD • Blinks red when the current being drawn reaches the unit’s continuous rating.
• Glows red when the current being drawn reaches the unit’s peak rating.
50 HZ • Glows green if the inverter’s output frequency is set to 50.00 Hz. This
setting can be changed using InverterWizard,
60 HZ • Glows green if the inverter’s output frequency is set to 60.00 Hz. This set-
ting can be changed using InverterWizard.

failure, sparks may be generated inside the unit.
Installation
IMPORTANT: BEFORE CONNECTING OR DISCONNECTING ANYTHING TO THE
INVERTER, MAKE THE UNIT IS OFF.
GROUNDING
The unit case is connected to AC Ground and AC Neutral in order to meet regulatory
requirements and reduce the possibility of it generating any radio frequency interference.
The unit case must be bonded appropriately to the grounding system of the vehicle or marine
vessel. On a vehicle, bond the case to the vehicle’s frame. On a marine vessel, bond the case
to the vessel’s hull. A grounding stud is provided on the front panel for this purpose.
To ensure proper grounding, check the connection with an ohmmeter. The case is isolated from
the DC input, so the DC power can be connected to a different ground from the AC output.
DISCONNECTING
If you need to disconnect the Inverter for service or storage:
1. Move the power switch to OFF and disconnect the DC power source.
2. With power disconnected, move the power switch to ON.
3. Leave the switch in this position for one minute to discharge the storage capacitors.
4. Return the power switch to the OFF position. Disconnect the load(s).
5. The inverter is ready for service or storage.

Off-line UPS Option
The Off-line UPS (Uninterruptible Power Source) option allows the inverter to function as a
backup power source in the event of external AC power failure. Units with the ofine UPS
feature are constructed with an AC Input connection and internal off-line AC Bypass circuit.

NORMAL OPERATION
• The AC power source supplies AC power
to the load (Running to AC Output through
AC input and the inverter’s off-line bypass
circuit).
• A battery is connected to the inverter’s DC
Input Connection(s) on standby. While the
inverter detects normal AC voltage, power
is not drawn from the battery.
Legend

AC POWER FAILURE
• The inverter detects a drop in AC voltage on
the off-line and automatically turns on and
starts operation.
• The inverter draws DC power from the
connected battery which supplies AC power
to the load.
• The inverter continues operating until it
detects that the AC voltage is restored or
the battery is discharged.
TO SET UP THE OFF-LINE UPS:
1. Connect the AC power source to the AC Input Connection.
2. Connect the DC power source (batteries) to the DC Input Connection.
3. Connect the load to the AC Output Connection.
4. Power on the inverter. The Bypass LED will glow green indicating the load is being
supplied with AC power through the inverter’s off-line bypass circuit.
5. If the AC power fails, the Bypass LED will turn off and the Invert LED and 50/60Hz LED will
glow green indicating the Inverter is operating.
TIP: ENSURE THE BATTERIES HAVE ENOUGH CAPACITY TO POWER THE INVERTER
FOR THE EXPECTED LENGTH OF AC POWER FAILURE.
For example, a 2000-watt inverter running from 24 VDC input will draw ~100 amps. For 2 hours of
run time, the minimum required battery capacity is 280 amps-hours of capacity @ 24 VDC.

1110
InverterWizard (Optional)
InverterWizard is optional software that can be used to adjust the inverter’s operating
settings. InverterWizard is free-to-download from www.analyticsystems.com or available by
emailing [email protected]
Using InverterWizard, you can:
• Set the inverter’s output frequency to either 50.00 or 60.00 Hz.
• Adjust the inverter’s output voltage over a ±10% range in 1 VAC intervals.
• Set the voltage thresholds for the low voltage alarms.
• Set the voltage thresholds for UPS function to start and stop.This function is only available on
units with the UPS option. See Off-line UPS for more information.
• Update the inverter’s rmware.
• Monitor and record the inverter’s operating data.
ALTERNATE DC VOLTAGES AND LOW VOLTAGE SHUTDOWN
These inverters are factory-preset for the low voltage alarm/shutdown to trigger if the unit
detects an input voltage drop of:
• <12 VDC for a 12 volt model
• <24 VDC for a 20 volt model
• <48 VDC for a 40 volt model
If the inverter uses an alternate input voltage such as 32 VDC, 36 VDC, or 72 VDC (rail) battery
then the low voltage shutdown thresholds will need to be adjusted using InverterWizard.
NOTE: INVERTERWIZARD IS NOT REQUIRED TO OPERATE THE INVERTER.
The inverter can immediately be put into service if its default operating settings are suitable
for your needs. The inverter’s default settings are listed its label.

Troubleshooting
This unit features eight LED indicators and an alarm buzzer to help diagnose any malfunctions
during operation. In the event of malfunction, the alarm buzzer will sound prior to the inverter
shutting down. You should immediately check which LEDs are glowing to determine the cause
of the malfunction.
TIP: FOR QUICK REFERENCE, IF THE UNIT IS EXPERIENCING A MALFUNCTION: THE INVERT
LED WILL BE OFF AND THE BYPASS LED WILL BE GLOWING RED.
LED / Issue Meaning
LOW VOLTAGE LED is ON The input voltage is too low for normal operation.
Fix: Check that the power source is appropriately rated for use with the
inverter. If using InverterWizard, check the Low Voltage Alarm thresholds
are properly set for the battery voltage you are using to power the inverter,
for example: 21V for a 24V battery and 28V for a 32V battery.
If the above are all in working order, the cause is likely an internal compo-
nent failure and the unit must be returned for repair.
HIGH VOLTAGE LED is ON The input voltage is too high for normal operation.
Fix: Check that the power source is appropriately rated for use with the in-
verter. The inverter can be damaged if the input voltage exceeds the rating
indicated on the label. Over-voltage damage is not covered under warranty.
If the above are checked and in working order, the cause is likely an inter-
nal component failure and the unit must be returned for repair.
OVER TEMP LED is ON The unit’s internal temperature is too hot for normal operation.
Fix: Check that the unit’s cooling fans are functioning. If the fans are NOT run-
ning, the unit must be returned for repair. If the fans are running, you may
need to remount the inverter for improved ventilation.
The inverter will automatically derate its maximum power rating to
maintain a safe operating temperature. If the internal temperature exceeds
the safe maximum, the unit will shut off its outputs. When the temperature
drops to safe operating range, the inverter will automatically recover.
OVER LOAD LED is ON The load is drawing too much current from the inverter.
Fix: The load has been drawing the peak current from the inverter for
longer than its intended duty cycle. Reduce the load on the inverter by
disconnecting some devices from the output.
