Installation Guidelines

• Ensure the relay is installed in a clean, dry environment protected from excessive dust and moisture.
• Verify that the control power supply matches the specified voltage range (80-300 V DC or 70-265 V AC) before applying power.
• Use shielded cables for analog inputs and outputs to minimize electromagnetic interference (EMI).
• Ensure proper grounding of the relay chassis to the panel ground bus to maintain signal integrity and safety.
• Perform all wiring connections while the system is de-energized to prevent accidental short circuits or damage to the internal electronics.
• Maintain adequate clearance around the unit to allow for proper heat dissipation and airflow.
