Battery String
Disconnect Switch
The battery stand is provided with four battery string disconnect
switches. One switch is provided for each shelf of batteries, and is
intended to serve as a means to disconnect a string(s) of batteries from
the plant for service. NO OVERCURRENT PROTECTION IS
PROVIDED. Each disconnect switch is connected in parallel to the
battery stand terminal plate. See Figure 5-10.
The disconnect switch alarm should be brought to the plant controller as
an open string alarm. This is a resistive battery open string alarm that
can be used with Millennium, Vector, and ECS controllers. Refer to
Drawing T-83280-30 for connection to the Vector controller.
The maximum rating for the disconnect switch is 125A, providing the
battery stand maximum output rating of 500A at either 24 or 48 volts.
DO NOT EXCEED THE MAXIMUM STAND OUTPUT/INPUT
RATING OF 500A OR SWITCH RATING OF 125A.
Other Connections
Input, output, and open string alarm connections are already made on the
stand. Connections for an optional remote disconnect feature are
available (see Section 9, Remote Power Off Switch (J85504C-1 List D).
