Materials And Special Tools Needed - Johnson Controls PCA2513 Installation Instructions Manual

• One installation instructions sheet

Materials and special tools needed

• Three fasteners appropriate for the mounting surface (M4 screws or #8 screws)
• One 20 cm (8 in.) or longer piece of 35 mm DIN rail and appropriate hardware for DIN rail mount
(only)
• Small straight-blade screwdriver for securing wires in the terminal blocks
Mounting
Observe the following guidelines when mounting a PCA controller:
• Ensure the mounting surface can support the controller, DIN rail, and any user-supplied
enclosure.
• Mount the controller horizontally on 35 mm DIN rail whenever possible.
• Mount the controller in the proper mounting position (Figure 1).
• Mount the controller on a hard, even surface whenever possible in wall-mount applications.
• Use shims or washers to mount the controller securely and evenly on the mounting surface.
• Mount the controller in an area free of corrosive vapors and observe the Ambient Conditions
requirements in Technical
• Provide for sufficient space around the controller for cable and wire connections for easy cover
removal and good ventilation through the controller (50 mm [2 in.] minimum on the top, bottom,
and front of the controller).
• Do not mount the controller on surfaces prone to vibration, such as duct work.
• Do not mount the controller in areas where electromagnetic emissions from other devices or
wiring can interfere with controller communication.
Observe these additional guidelines when mounting a PCA controller in a panel or enclosure:
• Mount the controller so that the enclosure walls do not obstruct cover removal or ventilation
through the controller.
• Mount the controller so that the power transformer and other devices do not radiate excessive
heat to the controller.
• Do not install the controller in an airtight enclosure.
