Warnings Hazardous Voltages The INPUT AND OUTPUT POWER connectors and cables of the SynQor UPS may have voltages that are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate safety precautions should be taken. All connections should be made in accordance with LOCAL ELECTRICAL CODES.
Hazardous Energies The INPUT AND OUTPUT POWER connectors and cables of the SynQor UPS 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 UPS’s chassis or ground.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. Always use the proper SynQor battery pack. See the battery replacement chart on page 36. Protection from the Environment The SynQor UPS is a ruggedly built product having its electronics and battery contained in sealed chambers.

“effective wire diameter”. This second approach gives a more flexible cable. For 10 ft long cables, SynQor recommends that for the UPS-1250 DC Output Series: • The AC INPUT cable has 3 wires (one for the ground) of 12 AWG •...
• Move the AC BREAKER on the rear panel of the UPS to the ON position. Note: Be careful to not toggle the ON/OFF switch during the setup. Doing so could cause the UPS to turn on and present a hazardous voltage at its output. 006-0007097 02/14/2019 Rev E 23 of 52 UPS-1250DC Guide www.synqor.com...
(if no power sources are present). • It is not necessary to move the AC BREAKER on the rear panel of the UPS to the OFF position. 006-0007097 02/14/2019 Rev E 24 of 52 UPS-1250DC Guide www.synqor.com...
UPS. However, the SynQor UPS is capable of having any of its input or output power cables connected at any time (if safely done), including when the UPS is turned on and delivering power to the load.
Operation Cooling System The SynQor UPS-1250 DC Output Series products are cooled by fans that draw air into the intake below the battery pack on the front panel and exhaust it out the two fan ports on the rear panel.
Each battery pack has 16 LEDs, as shown below, that indicated the status of the battery pack and of the operation of the UPS. LED A1 is permanently disabled. There is no AC outlet on the unit.

Of course, if there is no source of input power available and the UPS is therefore drawing power from the battery, then the removal of the battery pack would cause the UPS’s outputs to shut down until a recharged battery pack is inserted. 006-0007097 02/14/2019 Rev E 32 of 52 UPS-1250DC Guide www.synqor.com...
Operation Operating Environment The SynQor UPS-1250 DC Output Series is designed for the extreme environmental conditions of military and aerospace applications. All the electronic circuitry and the battery pack are contained in a sealed, weather-proof, shock-proof chamber constructed of die-cast aluminum.
In a normal battery configuration, the failure of a single cell would disable the entire battery. The SynQor battery packs are designed with their battery cells arranged in segments that can be disconnected from the other segments by the internal electronic circuitry.
Battery Pack Battery Capacity The SynQor UPS battery packs come in two versions: a Standard Battery Pack and a thicker, heavier Extended Battery Pack that provides a longer battery run-time. The Standard battery pack fits into the UPS-1250-S-1U and UPS-1250-S-2S units. It has approximately 200 watt-hours of energy storage and a recharge time of <2 hours.
(200 Watt Hours) BAT-0500-E-2U-000 Extended Battery Pack (500 Watt Hours) Other Options also available, check the website or contact power@synqor.com for further information. Always use the proper SynQor battery pack. 006-0007097 02/14/2019 Rev E 36 of 52 UPS-1250DC Guide www.synqor.com...
Federal DOT Requirements. A UPS may be shipped using standard shipping methods if it does not contain a battery pack. Please contact SynQor for further assistance. The battery pack should be disposed in accordance with applicable regulations of the locality or returned to a factory-authorized Service Center.

The RS232 port provides readback of UPS’s state, as well as the configuration and control of the UPS’s operation. The port can be used from a standard terminal interface, or from a custom computer application. 006-0007097 02/14/2019 Rev E 40 of 52 UPS-1250DC Guide www.synqor.com...
IP address assignment can be done via DHCP or user entry of a static address. The interface also supports a direct connection between the UPS and a host computer by including a DHCP server internal to the UPS.

CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. Always use the proper SynQor battery pack. See the battery replacement chart on page 36. Fans The fans on the rear panel have sealed bearings that do not require any maintenance. Fan assemblies are user replaceable with kits available from SynQor.
Trouble-Shooting Guide Fault Conditions The SynQor UPS has no user-serviceable parts within it (other than the fans). If it has an internal malfunction only a factory trained personnel should attempt to repair it. There are, however, several external conditions that could cause the UPS to not operate as desired.
