Notes for System Wiring
1. All signal and control wire must be 22-18 AWG wire. If 16 AWG is desired, use Molex #39-00-
0078 crimp pins (not supplied) instead of the parts supplied.
2. Resolver must be wired with three (3) sets of 2-conductor shielded pairs as shown.
Thermostat wiring must be a twisted pair.
3. Caution, the screws in the power terminal blocks are captive. Do not attempt to remove them
for using ring terminals. Use locking type spring spade terminals such as Hollingsworth
#XSS20954S or #SS20947SF for 16/14 AWG wire and #XSS20836 or #SS20832F for 12/10
AWG wire.
4. Wire gauge is dependent on application. For total axis currents less than 9-amps, use 16
AWG. For total axis currents greater than 20-amps, use 10 AWG.
5. Wire the power supply fault contact (rated 115 VAC 1 amp) to drop main 3-phase power (L
a
,
L
b
, L
c
) in fault conditions. (This contact is normally open, closed on power-up (approx. 0.250
ms) and opens in fault conditions.)
6. Fuse or circuit breaker sizing dependent on application.
PSR4
Recommended Fuse
12-amp
Buss #FAN-A-12 or equivalent
20-amp
Buss #FAN-A-20 or equivalent
7. Resistor must be mounted away from any flammable material. A 400 VDC potential is
present (maintain electrical isolation for this voltage rating).
8. All AC lines should be twisted cables.
