Installation & Mounting Guidelines

• The 140NOM21200C fits standard Modicon Quantum racks and requires no special tools for insertion.
• Ensure the bus current supply provides at least 780 mA to guarantee proper startup and functionality.
• Use twisted-pair copper cables for both RS-485 and RS-232 connections to maintain signal integrity at 1 Mbps.
• Install the module in environments with ambient temperatures between 0 and 60 °C for optimal performance.
• The conformal coating protects against moisture, but avoid exposing the unit to condensing humidity during installation.

Frequently Asked Questions (FAQ)
