There is no standard backfeed protection inside, please isolate the UPS before working according to this
circuit. The isolation device must be able to carry the UPS input current.
•
This UPS should be connected with
TN
grounding system.
•
The input power supply rating must be in accordance with your equipment (i.e., 3-phase or single-phase.) It
also must be suitably grounded.
•
Use of this equipment in life support applications where failure of this equipment can reasonably be expected
to cause the failure of the life support equipment or to significantly affect its safety or effectiveness is not
recommended. Do not use this equipment in the presence of a flammable anesthetic mixture with air, oxygen
or nitrous oxide.
•
Connect your UPS power module’s grounding terminal to a grounding electrode conductor.
•
The UPS is connected to a DC energy source (battery). The output terminals may be live when the UPS is not
connected to an AC supply.
1-5. Operation
⚠
Do not disconnect the earth conductor cable on the UPS or the building wiring terminals in any time
since this would cancel the protective earth of the UPS system and of all connected loads.
⚠
If the external battery cabinet is connected, the UPS output Anderson connector may be electrically live
even if the UPS system is not connected to the building wiring outlet.
⚠
In order to fully disconnect the UPS system, first press the “OFF” button and then disconnect the mains.
⚠
Ensure that no liquid or other foreign objects can enter into the UPS system.
⚠
The UPS can be operated by any individuals with no previous experience.

prevent disturbances.
Before working on this circuit
•
Isolate Uninterruptible Power System (UPS)
•
Then check for Hazardous Voltage between all
terminals including the protective earth.
