Installation - YASKAWA VS-616 Series Option Instruction Manual

INSTALLATION

1. Before attempting to install or use the Isolated Analog Monitor Card AO-12B2, read the follow-
ing instructions.
2. After unpacking the card, verify that you have received the correct code number and that no dam-
age 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/
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-
tom on each side of the cover. While lifting the cover, pivot the cover's bottom upward.
b) Larger inverters have screws to hold their covers in place that must be removed.
(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 Terminal No.12
(G) ground terminal screw.
