For the purpose of this document, a circuit is defined as one to seventeen AC Unison modules connected in parallel to a
dedicated 20A branch circuit. An array refers to the entire installation of one or more strings connected to the structure’s AC
service equipment.
- The ideal installation path is to begin closest to the installed transition box and plug in each module as you move away
from the box. Depending on the configuration of your array and the location of the transition box, this path may not be
feasible. For example, in a 2-row configuration, we recommend installing the bottom row first and working up toward the
transition box, which is likely mounted higher up the roof.
- Before connecting AC Unison module system to any premises wiring, check the AC service panel where the AC Unison
module System breaker will be located. Is there enough physical space in the Panel enclosure for the breaker? Is there
enough electrical capacity remaining in the AC Service Panel to handle the AC Unison module system breaker?
- Where is the junction box located in relation to the module that will connect to it?
Whether the box is located to the left or right of the array (as viewed from the ground facing the installed array) determines
which transition cable you need (male or female) and what preparation is needed for the final module in the string. With
the junction or transition box to the left, the transition cable will connect to the plug at the end of the AC cable. Therefore, a
female transition cable is required. The final module in the string will require a protective cap be plugged into the mid-cable
receptacle. With the junction or transition box to the right of the array, a male transition cable is needed, which will plug
into the mid-cable receptacle, and the final module will require additional cable management to secure the end of the AC
cable. Before connecting the transition cable, calculate the distance from the transition box to the module plus the
distance under the module to reach the appropriate AC connector. This will determine the length of transition cable that
you will need.
- Do you need any extension cables? Will the extension cable reach from connector to connector or is it necessary to
modify the standard cable management of one or both modules to make the connection easier?
If the extension cable is running across open roof, another cable management system might be needed to keep the
extension cable off of the roof and protected from the sun. If the distance to be crossed is longer than the length of the
extension cable, you can use more extension cables or transition back to standard building wiring systems to span the
distance. Use a transition cable to connect the module into a junction or transition box and wire according to local and
NEC or CEC standards. The preparation and installation instructions included in this section are general instructions for
installing AC Unison modules on most mounting systems. In some cases, it might be necessary to modify these
instructions to accommodate specific installation requirements.
