3. Notes
1. If smoke or flame is suspected or observed when working inside ESS container,
immediately activate emergency stop function of the ESS, disconnect main and
secondary circuit breakers and the fire extinguishers should be prepared to put out
the fire. If there is no open fire, after ensuring safety of personal and equipment,
FAT test may be continued.
2. Electric shock risk exits during the entire duration of the tests; Onsite Test
Engineers should be aware of safe operation and always keep a safe distance.
During the test, always follow the principle of one person conducting tests and
the other monitoring situation.
3. Faulty wiring during the test may damage instruments and equipment; before
commencement of test, all cables should be checked for defects.
4. Residual voltage in the equipment or instruments may lead to electric shock,
equipment must be discharged of stored energy before accessing. All operation
should only be conducted after verification that dangerous voltage is not present
5. Make sure that the ESS is not operated when test equipment are installed or
connected to system.
6. During the test, warning and safety signs should displayed at the site if
necessary.
