Test battery
This pocket battery connects to the Micrologic test connector. It powers up the
Micrologic and the Ready LED. It supplies the screen and allows settings to be made
via the keypad.
Battery module
The battery module is a back-up supply for the external power-supply module. The
input/output voltages are 24 V DC and it can supply power for approximately three
hours (100 mA).
24 V DC power-supply terminal block
The 24 V DC power-supply terminal block can be installed only on Micrologic 5/6 trip
units. It is required to power the trip unit when the trip unit is not connected to an
FDM121 display unit or to the communication system. When used, it excludes
connection of an NSX cord.
