Installation Guidelines

• Ensure the control system is powered down before installing or removing the IOTA or associated I/O modules.
• Mount the assembly securely on a standard DIN rail or via panel mounting points as specified in the system cabinet layout.
• Maintain proper grounding practices to minimize electromagnetic interference (EMI) and ensure signal integrity.
• Verify that all field wiring connections are tightened to the specified torque to prevent intermittent signal loss.
• Ensure adequate ventilation within the cabinet to maintain the operating temperature within the -20 to 70 deg C range.
• Handle with care to avoid electrostatic discharge (ESD) damage to the module interface pins.
