Connecting Your Shunt Module
(required for 22 kW system)
The procedures in this section assume that your shunt module is
already mounted. Wiring the shunt module consists of connecting
power from the system module and, depending on the shunt module
you ordered, connecting power to the fan inside the module.
Required Tools and Equipment
The required tools and equipment are:
• A small, flathead screwdriver
• User-supplied power wiring
• The two fan jumpers that came with your 1394-SR36AF shunt
module.
