Protection 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, and output connections are also protected against

transient excess voltage/surge events lasting no more than 10 msec.

Status indicators LED's indicate status of communications, running, errors, power, and digital
