Form 6 rack mount substation battery power interface
accessory
The substation battery power interface accessory is
designed for the Form 6 Rack Mount Control only. For other
control applications, contact your Eaton representative.
The factory-installed accessory, located in the mechanism
cabinet, is powered by a 24, 48, or 125 Vdc substation
battery, as specified at time of order. It allows the recloser
to be located up to 150 m (500 ft) from the control (see
Table 9). The Form 6 Rack Mount Control cable is wired to
the accessory, which transforms the control signal to trip
and close the recloser. Refer to Figures 8 and 9.
