Section I Warnings
Hazardous Voltages
The INPUT AND OUTPUT POWER connectors and cables of the SynQor MINV may have voltages
that are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate safety precauons
should be taken. All connecons should be made in accordance with LOCAL ELECTRICAL CODES.
• The MINV CHASSIS should be connected to earth or system ground with Ground Stud on the
rear panel, see mechanical diagrams.
• For the DC INPUT cable and connector:
▪ The rated DC input voltage of the MINV is below the level considered hazardous.
▪ The DC input terminals of the MINV are isolated from the AC output with reinforced safety
insulaon.
▪ However, never assume the terminals of the DC input connector or the wires of the DC input
cable are safe to contact, even if the MINV appears to be o.
• For the AC OUTPUT cable and connector:
▪ Do not assume that a hazardous voltage is not present at the terminals of the AC output
connector, even if the MINV appears to be o.
▪ Do not make contact with the terminals of the AC output connector.
▪ Connect the AC output cable to the MINV before the MINV is turned on.
▪ If connecon of the load to the AC output cable has exposed conductors, make this connecon
before connecng the AC output cable to the MINV.
▪ Connecons between the AC output cable and the AC load should not be accessible.
Hazardous Energies
The INPUT AND OUTPUT POWER connectors and cables of the SynQor MINV may be the source
of high levels of energy. Do not inappropriately make electrical contact between any terminal of
a connector and another, or between any wire of a cable and another, or between any terminal
or wire and the MINV’s chassis or ground. DAMAGING ELECTRICAL ARCS may result. Care should
be taken to avoid accidental electrical contacts of this sort.

Protecon from the Environment
The SynQor MINV is a ruggedly built product having its electronics contained in a sealed chamber.
It is capable of withstanding harsh levels of mechanical acceleraon, shock and vibraon,
temperature and pressure variaons, and exposure to water, salt, sand and dust within the levels
specied in the data sheet. THESE LEVELS SHOULD NOT BE EXCEEDED.
Do not obstruct the air intake in the front of the MINV or the fan exhausts in the rear panel of
the MINV while the MINV is operang.
User Serviceable Parts
The MINV fans are user replaceable with kits available from SynQor. Please contact the SynQor
factory for obtaining fan replacement kits and instrucons (Counter-Rotang Replaceable
Fan Module SYN-9452). The SynQor MINV has no other user serviceable parts inside of it. DO
NOT REMOVE the cover of the MINV or any of its connectors. Other than the fan assembly
replacement, only factory trained personnel should perform repairs.

Section II General Product Information
Product Descripon
SynQor’s Military Inverter units are designed for the extreme environmental and demanding
electrical condions of Military/Aerospace applicaons. SynQor’s MINV incorporates eld
proven high eciency designs and rugged packaging technologies. This MINV will accept a DC
input voltage while delivering a well-condioned connuous 4000 W, AC output to the load. It
is designed and manufactured in SynQor’s USA facilies to comply with a wide range of military
standards. Opons include a selecon of output voltage amplitudes, frequencies, and an
electronic breaker on the AC output to permit fault-tolerant parallel operaon for higher power
and/or N+M redundant systems.
A communicaon/control port is available to permit monitoring and control by a host computer
system. Front panel LEDs provide informaon on the status of the MINV.
The electronic circuitry within the MINV-4000 Series products is designed, qualied and
screened according to SynQor’s MIL-COTS Standards. It complies with the requirements of
MIL-STD-704F, MIL-STD-1399-300B, MIL-STD-1275D and MIL-STD-461F, as well as IEC-EN61000
specicaons for world-wide commercial ulity applicaons.
The MINV-4000 Series products are designed and manufactured to withstand the harsh
environments and use encountered in military applicaons. The electronic circuitry is contained
in a sealed chamber constructed from a die-cast aluminum chassis that is weather-proof and
shock-proof. Redundant, water-proof fans on the rear panel draw cooling air over the heat-sink
ns below the sealed chamber. Military-grade circular connectors are used, and oponal aached
connector covers are available for when the cables are not aached. The MINV-4000 Series products
comply with a wide range of tesng according to MIL-STD-810G.
The SynQor MINV-4000 Series products are designed and manufactured in the U.S.A.

Product Topology
The SynQor MINV-4000 Series products use an isolated topology that provides protecon to the
load from spikes, noise, surges, brownouts, blackouts, etc. in the input power sources. They also
provide smoothing of load transients and nonlinear load proles so that the input power source
is not subjected to these disturbances.
EMI lters are present at all external inputs and outputs.
Power ows from the DC INPUT through an isolated DC-DC converter. The AC OUTPUT is created
by an inverter that draws power from the mid-bus. The inverter provides high-frequency safety
isolaon and a pure-sinusoidal output voltage waveform. An oponal electronic breaker can be
added to the AC OUTPUT. This one pole hot side only electronic breaker allows for fault-tolerant,
glitch-free operaon when several MINV units are placed in parallel.
Bulk energy storage capacitors are connected to the mid-bus to help smooth imbalances in
power ow between the inputs and outputs of the MINV.
There is a communicaon/control port that provides a digital interface to a host computer system.
