Maintenance
Preventive Maintenance
No scheduled or preventive maintenance (other than battery replacement for TOU/Load
Profile versions) is necessary for the CENTRON Polyphase meter.
Line potential may exist on the battery terminals. Follow these
precautions:
•
Never short-circuit batteries (such as by measuring current
capability with an ammeter).
•
Do not recharge batteries.
•
Do not store or transport batteries in metal or other
electrically conductive containers.
•
Keep batteries separated. If stored in a container where
they can contact each other, face them in the same
direction to prevent short circuits.
•
Do not operate batteries at temperatures above 85°C
(185°F).
•
Dispose of batteries where they will not be punctured,
crushed, or incinerated.
•
Discard the battery using proper hazardous waste
procedures.
Corrective Maintenance
Because of the high level of integrated packaging and surface-mount components, on-board
component repairs are not recommended. The entire meter should be returned to Itron, Inc.
Customer Service for repair.
