Outputs 9 ~ 16 only accept the power from GV-AS400 circuit board. Check if your output
device meets the following absolute maximum ratings before connecting it to any of outputs
9 ~ 16.
Breakdown Voltage 350V DC / AC
Continuous Load Current 130mA

Note: Absolute Maximum Ratings are those values beyond which damage to GV-AS400
circuit board may occur. Continuous operation of GV-AS400 at the absolute rating level may
affect GV-AS400 reliability.
