CHAPTER 1: INTRODUCTION MUST-READ INFORMATION
850 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 1–45
• In Power factor monitoring, SWITCH-IN and SWITCH-OUT are mutually exclusive
settings.
• The relay is not approved as, or intended to be, a revenue metering instrument. If used
in a peak load control system, consider the accuracy rating and method of
measurement employed, and the source VTs and CTs, in comparison with the
electrical utility revenue metering system.
• In bulk oil circuit breakers, the interrupting time for currents is less than 25% of the
interrupting rating and can be significantly longer than the normal interrupting time.
• For future reference, make a printout of the conversion report immediately after the
conversion in case conversion reports are removed or settings modified from the 8
Series Setup Software.
Storage
Store the unit indoors in a cool, dry place. If possible, store in the original packaging. Follow
the storage temperature range outlined in the Specifications.
Use the factory-provided dust caps on all Arc Flash sensor fiber and connectors when not
in use, to avoid dust contamination in the transceiver and sensor plugs.
