Installation Guidelines

• Ensure control power is completely disconnected before mounting or wiring the basic unit.
• Mount the unit securely on standard industrial mounting rails inside a protected control cabinet, ensuring adequate vertical clearance for thermal dissipation.
• Connect the PROFIBUS DP network cable using proper shielding and termination practices to maintain signal integrity.
• Route low-level sensor and thermistor wiring strictly apart from high-voltage motor power cables to mitigate electromagnetic interference.
