Technical Specifications

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.

Compliance and Certifications

• CE (Low Voltage Directive / EMC Directive)
• UL Listed
• cUL
• EAC
