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.
