Digital Ready Unit Electrical Connections
See Table 28, and Figure 113 and the job-specific electrical drawings
before proceeding with field power and control wiring. See also the wiring
diagram provided on the unit ventilator right front access panel.
In addition, those unit ventilators equipped with optional electric heating
coil have electric heating coil power connections at right end only.
Procedure
1. Provide power supply to right end compartment to match unit
nameplate.
2. Wire leads provided from unit ventilator electric connection box
to load side of unit power switch (switch provided by AAF).
The junction box has 1"(25mm) and 2"(51mm) knockouts, located
10-1/2"(267mm) from right end of unit.
3. Provide ground wire from grounding screw in switch junction box
to switch ground terminal.

Use copper conductors only. Use of aluminum conductors may
result in equipment failure and overheating hazards. All wiring
in right hand compartment must be class 1.
4. Wire field power supply to line side of unit power switch. Wire
ground conductor to switch ground terminal.
5. Mount unit power switch in switch junction box and install switch
cover plate (provided).
6. Figure 121 (A) shows switch location for valve control units and
(B), (C) and (D) show location for Face & Bypass control units.
(B) is for 208, 230 and 265 volt units.
7. See figure 116 & 120 for terminal strip designations.

Rigorously adhere to field wiring procedures regarding proper
lockout and tagout of components.
To avoid electrical shock, personal injury or death:
1. Installer must be qualified, experienced technician.
2. Disconnect power supply before installation to prevent
electrical shock and damage to equipment.
3. Make all connections in accordance with electrical wiring
diagrams, and in compliance with national and local codes.
Use copper conductors only.
4. Do not exceed ratings of the device. This is a low voltage
device: Never apply more than 12VAC/VDC to any lead or
damage will result.
5. Avoid locations where excessive moisture, corrosive fumes,
or vibrations are present.
