Mounting
Safety guidelines
Follow these safety guidelines before mounting the controller:
Important:
When the air supply to the VAV box is below 10°C (50°F), make sure that
any condensation on the VAV box, particularly on the damper shaft, does not enter the
ZEC510 electronics. Mount the ZEC510 vertically above the damper shaft so that any shaft
condensation falls away from the ZEC510. Additional measures may be required in some
installations.
• Ensure that the mounting surface can support the ZEC510 and any user-supplied enclosure.
• Mount the ZEC510 on a hard, even surface.
• Use shims or washers to mount the ZEC510 securely and evenly on the mounting surface if
necessary.
• Mount the ZEC510 in an area free of corrosive vapors that matches the ambient conditions
specified in the
section.
• Provide at least 50 mm (2 in.) on the top, bottom, sides, and front of the controller for cable
and wire connections and adequate ventilation through the controller.
• Do not mount the ZEC510 in areas where electromagnetic emissions from other devices or
wiring can interfere with controller communication.
• Avoid mounting the ZEC510 on surfaces with excessive vibration.
• Wear the appropriate personal protective equipment (PPE). For example, a hard hat, safety
glasses, steel toe boots, and gloves.
Follow these additional guidelines when mounting the ZEC510 in a panel or enclosure:
• Do not install the ZEC510 in an airtight enclosure.
• Mount the ZEC510 so that the enclosure walls do not obstruct cover removal or ventilation
through the controller.
• Mount the ZEC510 so that the power transformer and other devices do not radiate excessive
heat to the controller.
Mounting the ZEC510
To mount the controller, complete the following steps:
1. Disconnect power from the controller transformer, the VAV box fan, and heater circuits if
applicable.
2. Set all the switches on the field controller to their known settings. See
