For 24V isolated enable, tie +24V of external power supply to AECOM2 at any axis D-sub, tie common return to
AECOM1. Replace RPAE2 with a 4.7 kΩ resistor pack. AECOM1 and AECOM2 are located on any 15-pin axis D-subs
(JX, JY, JZ, or JW). All pins labeled AECOM1 are connected. All pins Labeled AECOM2 are connected.
