2.4.2.9 Fan Power
WARNING
POWER TO THE FAN(S) MUST BE FUSED AT THE SOURCE
AT A LEVEL APPROPRIATE FOR THE SELECTED WIRING.
1. Connect input power (line or +) for the fan(s) to termi-
nal #1, shown in Figure 9, TC - Typical External Wiring
Diagram.
2. Connect input power (line2, neutral, or -) for the fan(s) to
terminal #2.
3. Connect the passed-through output power (line2, neutral
or -) to the fan(s) to terminal #3.
4. Connect the fused, switched output power to the fan(s)
to terminal #4.

The fuses built into the TC-100 are standard 1/4” x
1-1/4”, 250 Vac, 20 Amps maximum rating. Lower rat-
ings may be used, as required, based upon the appli-
cation’s power supply, wire size, and fan(s).
