Battery Pack
The Mounting Hardware Set (Cat. No 1771-BX), which consists of two
mounting brackets with screws, is mounted to the left side plate of the I/O
Chassis (Figure 3-13). When mounted, the brackets provide tracks on which
the Battery Pack slides.
The two alkaline batteries are installed in the Battery Pack (Cat. No. 1771-BB)
with the polarity shown in Figure 3-14. It is best to position each battery with
the seam facing down in case the batteries leak.
An optional lithium battery (Cat. No. 177-XO) can be installed in the Battery
Pack in place of two alkaline batteries. Refer to Publication 1770-950 for
lithium battery information. Be sure to follow all cautions associated with these
batteries. To use a lithium battery, the battery contacts must be repositioned as
follows (Figure 3-15):
Disconnect the 3-pin connector from the Battery Pack and remove the
Battery pack from the I/O Chassis.
Remove the battery contacts from the center barrier in the Battery Pack.
Remove the end battery contact (furthest from the front of the Battery Pack)
and insert it at center barrier.
