Installation and Start-up Guide
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, network, input, and output 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.
You attach a BT485 (not included) to a controller at the beginning and end of a
network segment to add bias and to terminate a network segment.
LEDs indicate status of communications, running, errors, power, and digital
outputs
