Wiring Shunt Module Fan Power

This procedure assumes that you have bonded, mounted, and wired
the power to your shunt module. The shunt fan can be wired for 115V
or 230V input. Use 16 AWG 1.3 mm
copper wire for all fan power wiring. The current draw of each shunt
module fan is shown in the table below.
For this input power:
115V AC
230V AC
Important: If you mount the shunt module outside the cabinet, the
shunt fan power wiring must be inside metal conduit to
minimize the levels of EMI and RFI.
To wire the shunt fan for 115V:
1. Verify that all 24V control or 360/480V input power is removed
from the system.
2. Open the front door of the shunt module.
3. Using a flat screw driver, remove the plate that covers the fan wire
access hole located on the bottom right side of the module.
4. Insert one wire from the 115V AC power supply into terminal 1.
5. Insert the other wire from the 115V AC power supply into
terminal 4.
6. Insert one of the jumper wires that came with your shunt module
into terminals 1 and 3. Refer to Figure 3.21 for the jumper's
location.
7. Insert the other jumper wire that came with your shunt module
into terminals 2 and 4. Refer to Figure 3.21 for the jumper's
location.
8. Tighten all screw terminals.
9. Gently pull on each wire to make sure it does not come out of its
terminal. Re-insert and tighten any loose wires.
To wire the shunt fan for 230V:
1. Verify that all 24V control or 360/480V input power is removed
from the system.
2. Open the front door of the shunt module.
3. Using a flat screw driver, remove the plate that covers the fan wire
access hole located on the bottom right side of the module.
4. Insert one wire from the 230V AC power supply into terminal 1.
