Installation Guidelines
-
Power Down: Always disconnect system power before installing or removing the module from the backplane.
-
Placement: For optimal performance, the module should be located within 8 slots of the system power supply.
-
Grounding: Ensure the DIN rail or panel is properly grounded to provide a low-impedance path for electrical noise.
-
Wiring: Use the 1769-RTBN18 terminal block. Ensure all field wiring is routed away from high-voltage AC power lines to prevent induced noise.
-
ESD Handling: Use standard electrostatic discharge (ESD) precautions when handling the module to prevent damage to internal circuitry.
