7. Open the front door of the shunt module.
8. Insert the wire from the system module terminal block labeled
COL in the top terminal on the left side of the shunt module.
Refer to Figure 3.20 for the terminal’s location.
9. Insert the wire from the system module terminal block labeled
DC+ in the bottom terminal on the left side of the shunt module.
Refer to Figure 3.20 for the terminal’s location.

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
°
