Applicable Industries: Small robotics, laboratory automation, medical devices, small CNC, 3D printers, pick-and-place, valve control, small conveyor systems

Installation Requirements:

• Mount on DIN rail (35 mm) or panel mount with M4 screws
• Ensure minimum 50 mm clearance above and below for natural convection airflow
• Connect EtherCAT cable (shielded, CAT5e or better) — Maximum segment length 100 m
• Connect braking resistor if bus voltage exceeds 310 VDC during deceleration
• Ground chassis to < 1 Ω earth

Precautions:

• Do not exceed 3 A continuous current without derating at elevated temperature
• Do not block airflow paths — Fanless design requires free convection
• Ensure braking resistor is connected when decelerating high-inertia loads
• Use shielded cables for all feedback connections
