890GTR Inverter Power Manual HA502996
System ground fault detection
Ground fault detection can be implemented using a third party leakage resistance device. Typical installation requires both AC and
DC connections to remain floating. Typical leakage resistance to ground is approximately 1.6 Meg Ohms for one 890GTR. Multiple
890GTR units on the same transformer winding will lower this resistance.

Ethernet connection
Control of the 890GTR is effected through a Ethernet based LAN. Connection to this LAN is using standard Cat5 Ethernet cable with
shield.
See Chapter 8 Ethernet.
