Installation Instructions
Please Read Before Installing
P/N 041882 Rev. A
Important Notes:
• For installation by a qualified electrician in accordance with all local and national
electrical codes.
• Use copper conductors only.
• For indoor use only.
• For 277 V~ applications, a suitable barrier may be required between the non-Class 2
and Class 2 wiring, per local and national electrical wiring codes. For your
convenience, the power interface includes an optional barrier.
• DO NOT install if product has any visible damage.
• If moisture or condensation is evident, allow the product to dry completely
before installation.
• Operate between 32 °F (0 °C) and 104 °F (40 °C) ambient.
• 0% to 90% humidity, non-condensing.
• Four 8-32 × 3/8 in (9.5 mm), serrated lid screws provided.

1. Remove the top cover to access the multi-sided mounting key holes.
Input: 120 V~/277 V~ 50 / 60 Hz
2. Mount the power interface per the options shown below.
Output: 96 W 24 V-
Notes
• A minimum of 3 in (76 mm) is required between any two power interfaces.
• Mount the power interface in a position where it can be easily located and accessed if service
or troubleshooting is necessary.
• Any other mounting configurations will require additional mechanical support. Improper
installation may result in hazards to personnel or property.

Mounting Surface
A barrier (included) in the wiring compartment separates non-Class 2 and Class 2 wires.
Barrier can be placed between the control and the output terminals (Option 1) or between the
input and the control terminals (Option 2).

WARNING: Shock Hazard. May result in serious injury or death.
Turn off power at circuit breaker before installing the unit.
1. Remove the top cover to access the terminal blocks.
2. Open the necessary knockouts to pass wires into the wiring compartment.
3. Determine the length and wire gauge from the power interface to the wireless controller
using Table 1.
4. If wiring wireless controllers in a multi-zone application, wire as shown in Wiring Diagram A.
