Interface Connections J10

Use Molex mating receptacle #39-01-2120 with #39-00-0039 terminals provided.

J10-1 to 8 are Enable/Disable for slots 1-8.

J10-9 is Vcc, J10-10 is Signal Ground, J10-11 is AC Power OK, and J10-12

is General Shutdown.

Attach terminals to 18-24 AWG stranded wire using Molex tool #11-01-0197.

FlexPAC Connections J1

Use Molex mating receptacle #39-01-2120 with #39-00-0039 terminals provided.

Attach terminals to 18-24 AWG stranded wire using Molex tool #11-01-0197.

J1 pins 11, 5, 12 and 6 are for special trim options. Contact factory for use.

Local Sense only.
