Keyscan Inc. A Member of the Kaba Group – CA150 Rev. B Installation Guide (07.15)
If terminating a RS-232 communication cable in the metal enclosure, ensure that the shield is insulated and
connected to the ground lug. Keyscan suggests Alpha PVC 10516 - #16 clear tubing or a comparable tubing to
insulate the shield. Do not connect the shield to GND on the RS-232 communication terminal block.
The metal enclosure includes 1 ground lug pre-mounted on the right side of the CA150.
Note
Keep all shield wires and cables away from the control board.
