Mounting
• PCM4 components are sensitive to electrostatic fields. Avoid
contact with the circuit board directly.
• Protect the PCM4 from dirt, moisture, and accidental
contact. Provide sufficient room for access to the terminal
block.
• Mount the PCM4 away from other heat sources. Operate
within the specified ambient operating temperature range.
The operating temperature range for the PCM4 is 0°C
through 50°C.
• Prevent loose connections by avoiding excessive vibration of
the process control module board.
• Mount the PCM4 in either a horizontal or vertical plane.
• The PCM4 is mounted using 4 – 0.25 inch [6mm] standoffs.
See Figure 1, page 2 for the physical locations of these
standoffs. Use #8 panhead screws to fasten the standoffs to
the mounting surface.
