The “R” option adds a single pole electronic breaker to the hot wire of the AC OUTPUT. This breaker allows for fault-tolerant, glitch-free operation of up to 32 MINV Units in a redundant N+1 or N+M multi MINV system. Therefore, “R” option allows customers to build redundant, Single-phase, Split-phase, and 3-Phase with SynQor’s MINV units. Each of these MINV systems can also be configured to be N+1 or N+M redundant on each phase. The block diagrams below show a summary of the different system configuration that can be made using units with the “R” and “F” option. Please note that each multi-unit system requires its own unique system CONFIGURATION (Single-phase, Split-phase, and 3-Phase) cable. Configuration cables are the same for the “R”...

(meaning at a high potential relative to the neutral or PEGND). One will be phase-shifted by 180 degrees (one-half cycle) from the other, meaning that when one hot wire is at its positive peak the other is at its negative peak, and vice versa. The voltage between these two hot wires is therefore twice that of either hot wire compared to the neutral wire. This configuration is called “Split-Phase”. When ordering, select the “F: Floating” or “R: AC Output Electronic Breaker” option for the MINV Units. Contact the SynQor factory for N+1 redundant Split-Phase systems.

Page 30: Series 3-Phase Connection Of Ac Outputs
Three expanded or redundant parallel MINV-4000-270 Units can be setup so that their AC OUTPUTs can share a common “neutral” and deliver output voltages that are phased by 120 degrees (one-third cycle) from each other. This configuration delivers a 3-Phase output where the line-to-neutral voltage is the rated voltage of the individual MINV Units (e.g. 115 Vac or 230 Vac line-to-neutral) and the line-to-line voltage is 1.73 times higher (e.g. 200 Vac or 400 Vac line-to-line). When ordering units for this configuration, make sure you select the “F: Floating” or “R: AC Output Electronic Breaker” option for the MINV Units. Contact the SynQor factory for N+1 redundant 3-Phase systems. The wiring diagram for the AC OUTPUT cables and the CONFIGURATION cables for the 3-Phase configuration is shown below: CONFIGURATION cable SYN-9617 Line 2 Line 1 Line 3... -

Page 37: Trouble-Shooting Guide
Section VII Trouble-Shooting Guide Fault Conditions The SynQor MINV has no user-serviceable parts within it. If it has an internal malfunction only factory trained personnel should attempt to repair it. There are, however, several external conditions that could cause the MINV to not operate as desired. These external conditions can likely be corrected by the user. The 11 LEDs on the front panel are the best and first place to look to determine what might be wrong with the MINV. The table on the next several pages is therefore organized by what these LEDs indicate, and for each indication there is a listing of what might possibly be wrong. The front panel LED array is shown below. The designations of the 11 LEDs in this array are used in the following table. Indication Possible Problem(s) • The DC INPUT power source is not turned on. - Page 38 • To reset, the MINV must be turned OFF and then ON. • One or more fans have encountered a fault or degraded performance. Four tones • The MINV may still operate with degraded fan performance, but will require service. Ensure the fan blades are not obstructed. 006-0007361 12/08/2022 Rev A 35 of 41 MINV-4000-270 Guide www.synqor.com...

- Page 40 Section VII Trouble-Shooting Guide Several problems could arise with such a load: • Loads that draw a large surge of current at start-up: SynQor’s MINV-4000-270 is designed to try various start-up routines when it is first turned “ON” to overcome the problem of surge currents with some loads. There are three such routines, and each routine will be attempted three times. If the load is not started after these three routines (9 total attempts), the DC/AC section will latch off. This causes the AC output LED A0 to turn AMBER. To get the MINV to try again, the user should again push the “ON/OFF” switch on the front panel to the “OFF” position, then back to the “ON” position. If there is more than one load connected to the AC OUTPUT that displays this start-up surge...
- Page 41 MINV may determine that the DC input is out of range and proceed to shut down. After this occurs, no current is being drawn through the input cables and terminals once again, the MINV detects that the DC input voltage is back to normal, and begins the startup sequence once again after a 1 second delay. The cycle will continue to repeat over and over, until voltage drop in the input circuit is corrected. The following are possible solutions to this problem: 1) make sure that the cable diameter for the required length is sufficient to deliver the full amperage to the MINV Unit, 2) tighten the distribution panel/breaker terminals or 3) clean any contamination or corrosion buildup on all terminals and connectors. 006-0007361 12/08/2022 Rev A 38 of 41 MINV-4000-270 Guide www.synqor.com...
