CHAPTER 10: MAINTENANCE
2.
With power to the unit off, disconnect individually the connections from the module before removing the module from
the chassis.
3.
To properly remove a module, pull simultaneously the ejector/inserter clips, located at the top and bottom of the
module. Record the original location of the module to ensure that the same or replacement module is inserted into the
correct slot. Modules with current input provide automatic shorting of external CT circuits.
To properly insert a module, ensure that the correct module type is inserted into the correct slot position. The ejector/
inserter clips located at the top and at the bottom of each module must be in the disengaged position as the module is
smoothly inserted into the slot. Once the clips have cleared the raised edge of the chassis, engage the clips
simultaneously. When the clips have locked into position, the module is fully inserted.
10.6 Battery
A battery powers the real time clock on startup of the device.
When required, the battery can be replaced. Because the power supply module contains the battery and there are two
power supply options, two procedures are possible. To determine which procedure to use, check the power supply module
or use the photographs here.
