Control I/O wiring
Motor feedback cables
Always separate all low voltage signal
wiring from high voltage power wiring to
reduce affects of EMI and RFI.
7. Open the front door of the shunt module.
8. Insert the wire from the system module terminal block labeled
9. Insert the wire from the system module terminal block labeled

DANGER
RISK OF ELECTRICAL SHOCK. HIGH VOLTAGE MAY
EXIST UP TO FIVE MINUTES AFTER REMOVING POWER.
ATTENTION: To avoid burn hazard and ignition of
flammable material, be sure to provide appropriate
!
guarding. The resistors inside the 1394 shunt module
can reach temperatures in excess of 350° C (662° F).
Install per local codes.
