4.1.3 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.
(Figure 4-10: External Battery Temperature Dry Contacts)
4.1.4 External Switch/ Breaker Status Dry Contacts
There are four sets of external switch/ breaker status dry contacts (S1, S2, S3 and S4),
which can be used to respectively detect the status of input, bypass, output and manual
bypass switches or breakers.
For connection to the external switch/ breaker status dry contacts, the signal cable routing
is the same as the REPO dry contacts’ signal cable routing.
NOTE:
Only trained Delta engineers can enable the function. Please contact Delta
customer service for implementation.
