2–18 Regenerative DC Bus Supply Operation
Control and Signal Wiring Control Board Connections
All customer control and signal wiring is made to quick-connect
terminal blocks J15 and J16.
The maximum/minimum wire sizes accepted by J15 & J16 is 3.3/
0.6mm
2
(12/30AWG). Maximum torque is 0.79N-m (7lb.-in.).
Recommended control/signal wire is:
• Belden 8760 (or equivalent) — 0.750mm
2
(18AWG), Twisted Pair,
Shielded.
• Belden 8770 (or equivalent) — 0.750mm
2
(18AWG), 3-Conductor,
Shielded.
• Belden 9460 (or equivalent) — 0.750mm
2
(18AWG), Twisted Pair,
Shielded.
If the converter control connections are to be linked to an
electronic circuit or device, the common or 0V line should be
grounded at the drive end only.
Important: Signal common (DGND) puts the common or
negative side of the signal at earth ground potential.
Control schemes must be examined for possible
conflicts.
All customer control and signal wiring shields are terminated at
the TE terminal block shown on the previous page.
Cable Routing
If unshielded cable is used, control and signal circuits should not
run parallel to motor, DC bus, or unfiltered supply cables with a
spacing less than 0.3m (1ft.). Cable tray metal dividers or separate
conduit should be used.
Important: If user installed control and signal wiring with an
insulation rating of less than 600V is used, route the
wiring inside the converter enclosure such that is it
separate from any other wiring or uninsulated live
parts.
