Chapter 3 Mounting the controller
Mounting recommendations
Mounting recommendations are as follows:
CAUTION
Mount the Tracer ZN521 zone controller with the cover on to avoid the possibility of damaging the circuit board during installation.
•Mount the controller in any position, other than with the front of the cover facing downward.
•Mount using the two 3/16 in. (4.8 mm) radius mounting holes provided (see Figure 4). Mounting fasteners are not included.
•Attach the controller securely so it can withstand vibrations of associ- ated HVAC equipment.
•When the controller is mounted in a small enclosed compartment, complete all wiring connections before securing the controller in the compartment.
