Mounting the
TrueAlert Isolator +
Module
The TrueAlert Isolator + module mounts to the 4-inch square grounded metal electrical box via 2
screws. Box depth is dependent on the number and size of conductors used in a particular
application. The range extends from a minimum 2 1/8" deep box to a 1 1/2" deep box with a
minimum 1 1/2" extension ring.
Caution: Do not bring conduit through the rear of the electrical box.
1. Tighten mounting screws snugly (do not over-tighten).
2. For semi-flush mounting, install the box either flush with the wall or with a maximum ¼-
inch recess.
The TrueAlert Isolator + Module uses terminals to connect to each wire point. Each accepts 2
wires of gauges #12 through #18 AWG. The terminal screws at TB1 accommodate both slotted
and Philips drive.
Refer to the Field Wiring Diagrams, or applicable installation manuals, for detailed information on
maximum wire run distance.
