3. Connect the wires coming from the power
source and the external device, following these
guidelines. See Figure 152 for further clarification.
a. If the application requires less than 3 amps, the
terminal block on the Crosswind V control board can be
used to drive power to the external device.
b. For applications over 3-amps, use a field-supplied
relay rated to the amperage and voltage of your
application, connected in cascade to the Auxiliary
output of the heater. See Figure 153.
4. Ensure that you follow the wire gauge and wire length
requirements specified for the external device. Use
the appropriate power source for your application. If
you are using field-supplied relays, make certain that
the coil is rated for the voltage of the external power
source.
