Jumper plug required If connector J29 is not used, you must install a jumper plug to maintain the
integrity of the interlocks. Use jumper plug PN 100-007-947B or jumper pins: 3-
4, 5-7, 8-13.
J43 Interlock
Connector J43 Interlock contains one optically isolated interlock input and one
relay contact interlock output.
Note The intlk out relay (Pin 6) is normally energized when no interlocks are
active. So even though Pin 6 is a NO (normally open) relay contact, it is
actually normally closed when no interlocks are active. Similarly, the intlk
out relay (Pin 8) is normally closed when no interlocks are active, so
even though Pin 8 is a NC (normally closed) relay, it is actually normally
open when no interlocks are active.

Cable specification
• 9 contact type D male EMI connector.
• Backshell–EMI metallized plastic.
• Cable–shielded twisted pairs (24 AWG minimum) with drain wire(s)
connected to the metallized backshell at the chassis.
Power characteristics Channel inputs can be 3 volts (minimum) and 26 volts (maximum) from an
external voltage source.
