User Line Connection
Overview
The User-line interface provides basic remote control and monitoring on
the Inverter using TTL logic signals. The available signals are an Inverter
on/off input, fault and Inverter-on flags as well as a configurable auxiliary
line. The aux output can only be configured when the Ethernet option
card is installed. The user lines are optically isolated with typical source/
sink capability of 10 mA. To prevent damage to this interface, do not
exceed 40 mA of source/sink current.
CAUTION
Do not bias this port more than 50 V DC to chassis.
