Installation Guidelines
-
Mounting: Ensure vertical installation on a flat, non-combustible surface to maintain correct airflow alignment.
-
Clearance: Maintain minimum clearance space around the unit housing as specified by the OEM manual to prevent heat accumulation.
-
Grounding: Connect the ground terminal directly to an independent, low-impedance ground point to minimize electrical noise.
-
Wiring: Shielded cables must be used for control and analog signal lines to prevent electromagnetic coupling.
