WARNING
PRECAUTIONS
1. Read this instruction manual in its entirety before installing the Isolated Monitor Card AO-12B2 or
operating the inverter with this card installed.
2. DO NOT connect or disconnect wiring, or perform signal checks while the electrical power is turned ON.
Failure to observe these and other precautions indicated in this manual will expose the user to high
voltages, resulting in serious injury or death. Damage to equipment may also occur.
!
CAUTION
NOTE
The Option Card uses CMOS IC chips. Therefore, the card could become damaged when physically
handled if static electricity is present. The person handling the card should wear a discharge strap to
eliminate the possibility of static charge (if present) affecting the card.
Failure to observe this precaution may result in equipment damage.

INTRODUCTION
The Isolated Analog Card AO-12B2 mounts to an inverter’s control board via connection to option port
3CN, and is used to output dual analog signals for monitoring the inverter’s status: output frequency, output current, etc. The signal level is jumper selectable for -10 to +10 VDC, 0-20mA, or 4-20mA ranges.
The channels are isolated from the inverter, but not from each other.

INSTALLATION
1. Before attempting to install or use the Isolated Analog Monitor Card AO-12B2, read the following instructions.
2. After unpacking the card, verify that you have received the correct code number and that no damage had occurred during shipping. Contact your YASKAWA representative should you require
any assistance.
3. Turn OFF the main electrical power to the inverter, and allow sufficient time (usually 5 minutes)
for the DC bus to decay to less than 50V DC. The DC bus voltage can be measured by removing
the terminal strip cover, and then using the B1/ and terminals located on the main terminal
strip.
4. Remove the inverter’s cover by first removing the digital operator.
a) For smaller inverters, push inward (on the cover) at the indented area located near the bot-
b) Larger inverters have screws to hold their covers in place that must be removed.

tom on each side of the cover. While lifting the cover, pivot the cover’s bottom upward.
(Refer to the VS-616/ VS-676 Series User’s Manual, if necessary).
5. Check that the indicator CHARGE lamp is OFF (power OFF indication).
6. Place the Monitor Card onto the standoff post in the Control Board, aligning the Monitor Card’s
connector with the Control Board’s 3CN connector. Refer to Fig. 1 Location of Isolated Analog
Monitor Card AO-12B2.
7. Gently, push the Monitor Card downward onto the standoff post until it protrudes through the
card’s mounting hole, while aligning and connecting the card’s female connector to the control
board’s 3CN male connector.
8. Connect the Monitor Card’ s grounding cable (green wire) to the control board’ s T erminal No.12
(G) ground terminal screw.
