Installation Guidelines

1. 1 Verify all power to the control panel or cabinet is disconnected and locked out.
2. 2 Securely mount the IM157 module onto the designated standard DIN rail within the enclosure, ensuring proper clearance for ventilation and wiring.
3. 3 Connect the incoming PROFIBUS DP cable to the appropriate terminals on the module. Ensure the cable shield is properly terminated at one end to a low-impedance ground point to minimize noise.
4. 4 Connect the module to the associated DP/PA coupler(s) using the specified cabling. Maintain signal integrity by adhering to maximum cable length and routing guidelines.
5. 5 Connect the 24 VDC power supply to the designated terminals, observing correct polarity.
6. 6 After verifying all connections, remove the LOTO device and re-energize the system. Commission the module according to project-specific network configuration procedures.
