The SS16A2 AVR is an update of the SS15A2 AVR. It is similar to the original SS15A2 in power and voltage
sensing capabilities but with new enhanced paralleling functions; the user can now select the CT inputs
either 1 & 5 Amp or use new A1 & A2 analogue signal inputs terminals for use with PLC paralleling
controls. It has new over-voltage excitation safety circuits to prevent damage caused by the accidental
detachment ofthe sensing wires or irregularities on the generator’s excitation circuits.

ATTENTION!!
Use an average-reading type voltmeter for voltage readings.
Do not use Meggers and high-potential test equipment that
could damage the AVR.
Secure all wiring connection. Do not install AVR at location
with too much vibration to avoid loose connections. Do not
touch the heat sink while operating.
