ATTENTION
※
This Automatic Voltage Regulator is not equipped with loss-Sensing Protection / Over Excitation
Protection. An additional Over-Voltage Protection device for load may be required to avoid possible
damage to the equipment or severe personal injury or death.
※
The connection wire for VR1, VR2 and A1, A2 must be shielded wire, the grounding wire of shielded
wire should be as close as possible to the AVR.
※
The A1 and A2 signal must be isolated from the power.
※
All the power of EA200A protection system were supplied by 24Vdc, the B+ and B- terminal must be
connected correctly, otherwise all the protection, Self-Excited, and the Field Current meter cannot be
used.
