Installation
Field Serviceability
Field Serviceability
The SEL-2414 firmware may be upgraded in the field; refer to Appendix B: Firm-
ware Upgrade Instructions. Configure an output contact to create a diagnostic
alarm for a self-test failure as explained in Section 4: Logic Functions. Use the
metering functions to determine if the analog front-end (not monitored by self-
testing) is functional. Refer to Section 10: Testing and Troubleshooting for
detailed testing and troubleshooting information.
The only field replaceable components are the power supply fuse and the real-
time clock battery. A lithium battery powers the clock (date and time) if the exter-
nal power source is lost or removed. The battery is a 3 V lithium coin cell, Ray-
O-Vac
®
BR2335 or equivalent. At room temperature (25°C), the battery will
operate nominally for 10 years at rated load. When the device is powered from an
external source, the battery experiences a low self-discharge rate. Thus, battery
life may extend well beyond 10 years. The battery cannot be recharged.
Fuse Replacement
To replace the power supply fuse, perform the following steps:
Disconnect or de-energize all
external connections before opening
this device. Contact with hazardous
voltages and currents inside this
device can cause electrical shock
resulting in injury or death.

DANGER
Step 1. De-energize the device.
Step 2. Remove the eight rear-panel screws, ground screw, plug-in
connectors, and the device rear panel.
Step 3. Remove the Slot A printed circuit board.
Step 4. Locate the fuse on the board.
Step 5. Remove the fuse from the fuse holder.
Step 6. Ensure fuse holder has not been damaged, bent, or deformed.
Step 7. Be sure to reform the fuse holder to ensure proper contact with the
new fuse.
Step 8. Replace the fuse with a time delay, 5 x 20 mm, 3.15 A, high
breaking capacity, 250 V fuse (T315H 250 V).
Step 9. Insert the printed circuit board into Slot A.
Step 10. Replace the device rear panel, reinstall all screws and connectors,
and energize the unit.
Real-Time Clock
Battery Replacement
To replace the real-time clock battery, perform the following steps:
Step 1. De-energize the device.
Step 2. Remove the eight rear-panel screws, ground screw, plug-in
connectors, and the device rear panel.

CAUTION
Step 3. Remove the Slot B printed circuit board.
Step 4. Locate the battery clip (holder) on the board.
Step 5. Carefully remove the battery from beneath the clip. Properly
dispose of the old battery.
Step 6. Install the new battery with the positive (+) side facing up.
Step 7. Insert the printed circuit board into Slot B.
Step 8. Replace the device rear panel, reinstall all screws and connectors,
and energize the unit.
Step 9. Set the device date and time.
The device contains devices sensitive
to Electrostatic Discharge (ESD).
When working on the device with the
front panel removed, work surfaces
and personnel must be properly
grounded or equipment damage may
result.
