o
Remove the old battery from the snap-on connector using the plastic battery grip
shown in Figure 9-1.
o
Remove the battery grip from the old battery, and place the grip on the new battery.
o
Observing the polarity and firmly insert the new battery into the snap-on connector
shown in Figure 9-1.
o
Connect the ribbon-cable between the CPU (
¯
) board and the front panel. Be espe-
cially careful not to bend any of the connector pins! Do not use any force! Be sure that
the plug connectors latch.
o
Carefully replace the front panel being mindful of the ribbon-cable. Fasten the panel
to the case with the screws.
o
Replace the covers.
o
Close the protective switches to apply voltage to the power supply.
o
After the device is operating, data saved in DIGSI
®
4 can be loaded back into the de-
vice.
If the internal system clock is not automatically synchronized via a serial interface,
then the clock should be set at this point. Refer to Sub-section 7.2.1 if assistance is
needed to set the clock.
9.3.1.2 Battery Replacement for a Device with Detached Faceplate
The battery is located near the front edge of the CPU printed circuit board. If battery
replacement is necessary, this battery does not need to be replaced. In the faceplate
of the unit, there is a clamp fixture for a battery, labelled G2.
To replace the battery:
o
Save the waveform captures and the important data under the Annunciation sub-
menu (all items in this sub-menu). The records and data are lost when the battery is
removed. The simplest and fastest method for saving the records and data is to use
the save feature in DIGSI
®
4 when the program is on-line.
Note: All of the protective and control settings, including the input/output configuration
and the CFC logic, are not affected by a power supply interruption. The settings are
saved independently of the battery. The settings are not lost when the battery is re-
moved, nor are the settings affected if the device operates without a battery.
o
Have the replacement battery ready.
Warning!
The used battery contains Lithium. Do not throw the battery into the trash!
Do not reverse the polarity! Do not completely discharge! Do not throw the bat-
tery into a fire! Explosion hazard!
Caution!
Do not short the battery! Do not reverse the polarity of the battery! Do not lay the bat-
tery under the ground mat used to protect components from electrostatic discharges!
Do not recharge the battery!
