Technical Specifications

Installation Guidelines

• Ensure the system is powered down before inserting or removing the module from the rack.
• Mark all existing wires with their connector IDs before detaching the old unit to ensure correct reconnection.
• Maintain physical separation between control/communication wiring and high-power input/motor cables to prevent electromagnetic interference (EMI).
• Route cables through designated cabinet grommets and ensure cable clamps are tightened on the stripped sections to maintain a secure, low-impedance ground.
• Handle the module using standard ESD (Electrostatic Discharge) precautions to prevent damage to sensitive internal circuitry.
