Battery-backed real-time clock keeps track of time in event of power failure
10-year Lithium CR123A battery ensures the following data is retained for a maximum
of 720 hours during power outages:
• Time
• Graphics
• Control programs
• Editable properties
• Schedules
• Trends
To conserve battery life, you can set the driver to turn off battery backup after a
specified number of days and depend on the archive function to restore data when the
power returns.
A low battery is indicated by the Battery Low LED or a low battery alarm in the i-Vu®
application, a touchscreen device, and Field Assistant.
Built-in surge and transient protection for power and communications in compliance
with EN61000-6-1.
Incoming power and network connections are protected by non-replaceable internal
solid-state polyswitches that reset themselves when the condition that causes a fault
returns to normal.
The power and network connections are also protected against transient excess
voltage/surge events lasting no more than 10 msec.
CAUTION To protect against large electrical surges on serial EIA-485 networks,
place a PROT485 at each place wire enters or exits the building.
