Sense Connector J2 (and P2 for the FinQPAC):
n Sense connections do not have to be made if either the Local Sense option was
ordered (older units) or if Autosense is present (see previous note on Autosense.)
n Attach opposite ends of Sense lines to point where regulation is desired.
n Verify that Sense lines are not cross-connected before applying input power.
n For the QPAC, J2-7 is the +Sense and J2-6 is the -Sense.
n For the FinQPAC, P2-7 is the + Sense and P2-6 is the -Sense.
n Use Molex mating receptacle #39-01-0073 with #39-00-0031 terminals provided
n Attach terminals to 22-28 AWG stranded wire using Molex tool #57005-5000.
Sense Connections on DualQPACs:
n Sense connections do not have to be made either if the Local Sense option has
been ordered or Autosense is present (refer to note on Autosense).
n Sense connections are available on the J2 connector (P2 for the FinQPAC)
or the J1A (M2) and J1B (M1) connectors.
n If using J2 or P2 connector, see instructions on Page 12.
n On J1A and J1B, Pin 3 is the +Sense and Pin 6 is the -Sense.
n Use Molex mating receptacle #39-01-2060 with #39-00-0039 terminals provided.
n Attach terminals to 18-24 AWG twisted pair wire using Molex tool #11-01-0197.
n Verify that Sense lines are not cross connected before applying input power.
Trim Pin Connection J2 for QPACs (and P2 for FinQPAC)
n The Trim J2 connection should only be made if the Trim option has not been
installed. (A “T” or an “F” in the ConverterPAC part number means the Trim option is
installed; ex. M5V/40AT.)
n For the QPAC, refer to J2 Connector. J2-5 provides Trim Access.
n For the FinQPAC, refer to P2 Connector. P2-5 provides Trim Access.
n Use Molex mating receptacle #39-01-0073 with #39-00-0031 terminals provided.
n Attach terminals to 22-28 AWG stranded wire using Molex tool #57005-5000.
Trim Pin Connection J2 for DualQPACs
n The Trim J2 connection should only be made if the Trim option has not
been installed.
n J2-7 is Trim B and J2-6 is Trim A.
n Use Molex mating receptacle #39-01-0073 and #39-00-0031 terminals provided.
n Attach terminals to 22-28 AWG twisted pair wire using Molex tool #57005-5000.
