Chapter 4 | Installing a Remote Battery Disconnect |
The remote battery disconnect is crated separately for shipping. The enclosure is designed to be free‐standing. You can install a remote battery disconnect anywhere between the remote DC supply and the UPS, according to national and local codes. Figure 4‐1 shows a typical remote battery disconnect enclosure.
The remote battery disconnect is set according to the operation procedures in Chapter 9, “UPS Operating Instructions.” When service personnel are performing maintenance on the UPS or battery string, the disconnect should be set to the OFF position.
