External Battery Temperature Dry Contacts

You can use the external battery temperature dry contacts (BT1, BT2, BT3 and BT4) to
detect at maximum four external battery cabinets' temperatures. You need to purchase the
battery cabinet temperature sensor cable (optional).
For connection to the external battery temperature dry contacts, the signal cable routing is
the same as the REPO dry contacts' signal cable routing.
