"N" is most likely a neutral terminal for a "Y" configuration 3-phase input or a single phase control supply. Check the installation manual to be sure. The qualified installation electrician should
For multiple battery cabinets incorporating battery disconnects, the cabinets are bolted together, forming a single lineup with the UPS. The cabinet grounds are inherently connected to the UPS ground bus
Route the ground wire (from the field kit) from the ground stud in one battery cabinet, under the lower battery tray and through the cabinet-to-cabinet cable access area in the side of the cabinets, and
Installation or replacement of batteries must be located in a SERVICE ACCESS AREA: The service manual shall include the following instructions for battery replacement and disposal:
Clearly distinguish the final exposed positive and negative terminals to prevent incorrect connections; the positive terminal connects from the air switch to the terminal block, and the negative terminal
"N" is most likely a neutral terminal for a "Y" configuration 3-phase input or a single phase control supply. Check the installation manual to be sure. The qualified installation
To check for inadvertent grounding of the battery, use a digital multi-meter set to the DC Volts scale to measure the voltage between any battery terminal and either the cabinet framework or AC neutral.
In the above-mentioned instances, the UPS neutral output must be connected to the equipment grounding conductor in addition to the local grounding electrode connection (EGC).
During installation, the positive pole is connected to the negative pole and installed in series. The neutral wire is drawn from the negative pole or positive pole of the 8th battery in the
The results show that the battery pack with cell firstly connected in parallel and then assembled in series can better reduce the influence of cell parameters variation, achieve more performance and greatly
