See note.
Note An automatic reset fuse is provided to protect output. If the fuse is activated for overcurrent, it
will automatically reset after a fixed period of time has lapsed without current flowing.
Backup Battery + Input (14: BAT)
■
Backup Battery − Input (15: BATGND)
• These are the connection terminals for a backup battery for when power to the absolute encoder is
interrupted.
• Normally a Backup Battery Unit is used and the battery is connected to the battery holder for the
absolute encoder battery cable, so do not connect anything to these terminals. (Absolutely do not
connect to both of them, or it will cause damage.)
• The battery voltage is 2.8 to 4.5 V.
