PEAK® IOM57 Input/Output Modules Installation Instructions

Mounting
Observe these guidelines when you mount a field controller:
•
Ensure the mounting surface can support the controller, DIN rail, and any user-supplied enclosure.
•
Mount the controller horizontally on a 35 mm DIN rail whenever possible.
•
Mount the controller in the proper mounting position Figure 1.
•
Mount the controller on hard, even surfaces 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 that is free of corrosive vapors, and observe the ambient conditions
requirements in
PEAK IOM57 Series technical specifications
•
Provide for sufficient space around the controller for cable and wire connections to ensure 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 vibrations, 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 you mount a field 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.
DIN rail mount applications
Mounting the controller horizontal on 35 mm DIN rail is the preferred mounting method.
To mount a field controller on a 35 mm DIN rail:
1. Securely mount a 20 cm (8 in.) or longer section of 35 mm DIN rail and mount the controller in the horizontal
and centered position, as shown in Figure 1.
2. Pull the bottom mounting clip outward from the controller to the extended position, as shown in Figure 2.
3. Hang the controller on the DIN rail through the hooks at the top of the DIN rail channel on the back of the
controller, and position the controller against the DIN rail. See Figure 2 for details.
