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.
